Some Notes From My Urban Farm

Hey everyone, I hope your gardens are coming along nicely despite the abnormal weather (characteristic of a fossil-fueled changing climate, of course). I decided to use today’s column to discuss a few observations, notes, thoughts, and updates from my own urban farm, as it has developed this year. I’ve never done something exactly like this before, but I think it might be helpful to share my experiences with my nearby urban farmers, who can hopefully relate and put them to good use.

This year has NOT been a good one for leafy greens in my garden. It was cold and wet pretty late in the winter, which delayed planting my spinach and lettuce until like April. And it’s been cloudy and cool far too often since then, so now that they are finally established, this onslaught of dry heat is making them bolt! It’s a shame because leafy greens are my favorite vegetables, in no small part because they are the most nutrient-packed plants you can eat. Hopefully you all are having better luck than I am.

It makes me particularly glad that I’m a member of Blue Skys Farm’s CSA program. Each week’s bag is packed with vegetables, including plenty of high-quality greens. Christina and the crew sure know how to grow them, even when the rest of us aren’t having such luck!

Gone are the days of a nice, gradual increase in temperature, and regular, light rain showers over the course of the spring. Climate change is already beginning to wreak havoc on our growing season in the Northeast US. While it’s intellectually irresponsible to attribute a particular weather event to increasing CO2 concentrations, it’s pretty safe to say that we are seeing the effects of climate change in the general shift of our day-to-day weather.

These torrential downpours, alternating with stretches of dry, oppressive heat…this weather is horrible for agriculture. It’s hard to make up for the heat with routine watering (especially if you don’t have 6 inches of mulch), and the massive downfall of rain is only beneficial if it’s followed by a kiss of sun, not another week of clouds. Until we get our act together and globally reduce carbon emissions, this unpredictability and extremeness is the new normal – and it’s only going to get worse from here.

With that said, I think the above-freezing temperatures are here to stay for the season, so I’m planning to plant my warm weather crops over the next few days. I put it off a week or two this year because of how busy I was in late May and early this month. But they’re hardened off and ready to go.

The tomatoes are a little leggy, probably because my house isn’t super temperature-controlled and my seed-starting setup isn’t heated, so they fell victim to the fluctuating temperatures over the past few months. But the eggplants and peppers are generally doing pretty well, so I’m excited for some home-grown, homemade melitzanosalata (a garlicky, Greek eggplant paste that I could eat at every meal) and meat-and-cheese-stuffed-peppers later this summer. Now, let’s hope the weather stays warmish and the rain comes a bit more regularly, so these babies can take off once they’re planted.

My raspberries, blackberries, and elderberries are doing great this year, which is hardly a surprise considering how closely related they are to their wild ancestors. They leafed-out beautifully, they’ve made a surprising number of new canes, and there is a good mix of buds, flowers, and immature fruits on the plants as I write this. This is great news, because bramble fruits are my second favorite foods from the plant kingdom after leafy greens, again and in no small part because of how nutrient (and fiber!) dense they are. Now, if only I could raise red meat animals in my yard, I would never have to buy food again! (Hmm, maybe it’s time for another change to Woonsocket’s Zoning Laws?)

My grapes, blueberries, and other fruiting bushes are doing moderately well this year. I’m hoping for a better crop than last year’s dismal one, so I’m trying to water them more than normal. But the strawberries: they’re doing awful. I’m not sure exactly what it is, but the general sentiment I’ve heard is that strawberries in our area are pretty bad this year. It’s likely the same abnormal weather patterns I discussed above, especially because groundcovers tend to like cooler, sunny weather and even moisture. I might dig them all up this fall and move them to a new location, being a little more methodical with the layout, and mulching like it’s my job. We’ll see. I’m enjoying what is being produced, but it isn’t much thus far.

This year was being forecast as the Gypsy moth apocalypse. I haven’t seen that much evidence of the larvae, not nearly as bad as a few years ago, but it may just be a function of my microclimate. Anyone else have a problem in their yard? I’ve talked to some people who live in the central part of RI, who said it’s bad down there. The one good thing that might come from this weather is that they don’t thrive like they were supposed to; that, or it’ll aid in the proliferation of those much-sought-after viruses and fungi that are said to keep the larvae populations in check. Time will tell.

Are you all aware of the origination of the Gypsy moth problem? They were indigenous to Europe, and brought over to Southern MA in the mid 1800s, by a scientist who wanted to experiment on them to produce cheaper silk. They escaped into the wild and spread like wildfire across the Northeast, because they didn’t (and, I believe, still don’t) have natural predators in our area. And now, they needlessly risk the health of our gardens and farms. Have you ever benefitted from cheaper silk prices? I sure as heck haven’t.

This should be a lesson for everyone who scoffs at the DEM and EPA for regulating the movement of plant and animal materials. Regulations like this are in place for a reason. Ecosystems are pretty resilient, but in a perfectly wild setting, they aren’t supposed to be constantly bombarded by species or populations from the other side of the world, or even from hundreds or thousands of miles away. And when they do, there is a significant possibility that the new organisms harm the natural environment.

Other than the Gypsy moths, I’ve always had a huge problem with winter moth larvae, on my apple trees in particular. I started to see it sometime in late April/early May this year, when the trees began budding out, so I made an executive decision: I used foliar Bt spray for the first time in my life. Bt is a soil-borne bacteria, which seems to have evolved to keep populations of destructive insect larvae in check. The spray is approved for use in organic farms, and of all crops, ultra-hybridized, grafted, non-well-adapted apple trees probably wouldn’t survive without a little extra help (but please let me know if you have proof to the contrary). I didn’t make the decision lightly, but the organic spray is certainly effective and is not harmful to human health and not persistent in the environment, so I deemed it acceptable.

Finally, here’s something I’ve been giving a lot of thought to. In the most general sense possible, we all have different personalities and drives and motivations, which mean that different approaches to the same problem work well for each of us as individuals. This is very true of how we approach creating and maintaining our gardens and urban farms.

In my case, looking specifically at the Myers-Briggs Type Index, I test as an ENFP (“Extroverted-iNtuitive- Feeling-Perceiving”), which explains why I get very enthusiastic about projects at the beginning, but often lose interest if they require a lot of repetitive, mundane maintenance tasks. Thus far, I have gardened in the typical way, which has produced a lot of mental fatigue around having to weed and water (especially if pests or other things beyond my control detract from the success of the garden), and often means I don’t keep up with that type of upkeep as well as I should.

I could certainly force myself to do these tasks, but it significantly detracts from the enjoyment of the garden. Armed with this knowledge, I have more incentive to create what I’m calling “passive maintenance systems”, that allow most of my mental effort associated with the garden to be used for creative pursuits (i.e. planting the next thing, reacting to good and bad weather events, harvesting) than routine maintenance (weeding and watering). These passive maintenance systems include things like drip irrigation to supplant direct watering, mulching to prevent weeds (and actually reduce the amount of water necessary), and permaculture design to make the whole thing function more like an independent ecosystem.

That’s my type. In general, it’s important to the success of our urban farming endeavors to tailor them to the way we think and behave, to maximize the likelihood of success and make it as fun and rewarding as possible. And in the end, there is nothing more enjoyable than a bowl of raspberries or tomato salad that was on the plant 20 minutes before.

I have one quick request. I have been writing this column for three and a half years now (!!!). I’ve written about a lot of exciting topics, and I have a long list of ideas for the future. But I want some input from you. If there is a topic you’d like me to discuss – anything from “hands-on” gardening ideas, to exposés on agricultural or environmental issues, to philosophical discussions about our place in the world – email me about it and I’ll try to make it happen!

The Call, Column 66 – Acting on Climate Change

26 02 2017

(February 26, 2017)

The Urban Farmer

Acting on Climate Change


This is the 21st century, and the science is beyond settled. Climate change is happening, it’s our fault, and we need to stop it. This is no longer up for debate. In the last two columns about this, I discussed the science of how climate change works, and gave you an idea of the grand scheme of society-level actions that need to occur in order to solve it.

Today, we’re going to narrow focus down to the radical individual action that is required of each of us, in order to prevent the disastrous effects of climate change and usher in an age of environmental sustainability.

Action on the individual/familial level. There are a variety of ways that we, as individuals, can reduce our carbon footprints and contribute to the remediation of climate change.

Energy efficiency is the first that comes to mind. It may seem mundane, but reducing our demand for energy not only literally prevents some of the carbon dioxide from being released into the atmosphere that otherwise would, but also eases the strain on our fossil-fuel-dominated energy sector, giving renewable energy sources an economic foothold to take over.

Change your light bulbs to LEDs as soon as you can get to Job Lot or Walgreens. National Grid heavily subsidizes LED light bulbs in our area, to the point where the difference in cost between them and incandescents (and even CFLs) can be made up by the electricity bill savings after a few months of use; that isn’t even counting the fact that LEDs last like 23 years, compared to incandescents’ 8 months. This change alone would reduce a normal household’s electricity consumption by almost 10%!

There are companies, like RISE Engineering, that you can bring in to do a free energy efficiency audit on your home. They determine if you are losing heat through your windows or air leaks or inadequately-insulated walls, and more generally look at your energy usage to find ways you can save. And then, they give you access to heavily discounted solutions.

It sounds cliché, but you can do a lot by simply paying attention to your energy usage, and working to reduce it. Turn off lights and electronic devices (like computers and TVs) when not in use. Lower your thermostat’s temperature (or turn off your air conditioner) when you aren’t home. Walk and bike and take public transportation wherever you can. In short, behave as if energy is a precious, limited commodity…because until we move to fully-renewable energy, it absolutely is.

The food we eat can also be a huge source of carbon emissions – or, if we source it right, it can actually remove carbon dioxide from the air. The basic idea is to eat foods that require as little fossil fuel input, and as little soil tillage, as possible, while encouraging perennial planting that sinks carbon dioxide into the soil.

Grains and legumes are the basis of non-sustainability in agriculture, as is anything that relies on them – like grain-fed animals. They uniquely require large amounts of fossil-fuel based fertilizers, and other fossil fuel inputs in the form of large farm machinery (to till, plant, spray, and harvest), not to mention the carbon dioxide released into the air during tillage. This immense release of greenhouse gas is to the tune of 10 units (i.e. Calories) of fossil fuel energy for each 1 unit of food energy produced!

The effect is exacerbated when livestock are fed mostly grains and legumes, especially ruminants like cows, which convert grains to meat less efficiently than other livestock (because they are supposed to eat grass!).

So what does this mean for our individual food choices? As urban farmers, I don’t need to tell you the benefits of growing your own. Generally speaking, growing your own anything is better for the environment than buying it as a product of conventional agriculture. It requires less fuel to transport and store, it takes basically no fossil fuel inputs (unless you have a backyard tractor you aren’t telling me about), and in the case of chickens, a portion of their conventionally grain-based diet is instead made up of pasture plants and insects.

Beyond that, sourcing food from the local foodshed, irrespective of growing methods, generally reduces carbon outputs from transportation; and buying from truly sustainable and/or organic farms means that artificial (carbon-based) fertilizers were not used, and the overall environmental impact is minimized. When it comes to meat, grass fed is a must whenever it is natural to the animal (cows, goats, sheep…any ruminant), and pasture- or forest-raised for any other animal (poultry, pigs) so their diet is maximally supplemented with foods other than grains. Extra points if you get these from the local foodshed, to reduce transportation outputs.

Finally, each time a piece of food is wasted, all of the carbon emissions associated with growing it were emitted for naught. We are all guilty of it – forgetting about something in the fridge, or in the pantry, and only finding it once it’s past its prime. By keeping animals (like chickens) that are perfectly willing to eat foods that are unpalatable for us but still “edible”, we can reduce the damage by a pretty big factor. But we should all practice better management to avoid food waste in general.

On a slightly higher grade of individual action, we all have the power to literally supplant dirty energy sources with clean ones. The easiest way to do this is to pay a little more for electricity to guarantee that it comes from 100% renewable sources. For National Grid, this is called the GreenUp program ( I only just discovered this, but will immediately be signing up for it. For a normal household’s energy use, $14 more per month means that 100% of your electricity comes from renewable resources!

In addition, a radically-active household can supplant the fossil fuels burned in their name by having renewable energy systems installed – whether that be solar panels on their roof to provide electricity, an electric car in their driveway, or passive solar heating to heat their water and home. This is a greater commitment of time and effort than paying the above, but it can actually cost less – renewable energy installers often have pricing structures available that allow you to pay off the loan for the system with no more than your electricity or heating bill would have been; this, on top of the subsidies available from the state and federal government for these types of systems.

Action on the community level. They say that change starts at home, and it’s certainly true in this case. If every person in the Western world woke up tomorrow and decided to implement the changes above, climate change would be solved. But we know that isn’t going to happen. The costs associated with these actions, the accessibility of renewable food and energy resources, the time to implement these changes, and knowledge about what to do are all reasonable roadblocks that make radical individual action difficult on a wide scale. There is also the nagging problem of science denial, which plagues a fraction of people in basically no other country but our own.

It is incredibly important to do as much of the above as possible, because the ultimate goal is for it to be the norm if we wish to solve climate change. With that said, solving the problem in an acceptable timeframe means using the government for what it’s for: protecting the common welfare, the valuable things (like environmental health!) that aren’t naturally protected by markets or individual action.

I promise, I will write more about this in the future as specific possibilities arise (I’m really running for that state-level carbon tax I wrote about last time!). But for right now, there are a few things you can do at the community level to foster change.

Call your representatives! Let them know you support comprehensive climate change legislation (cap and trade and a carbon tax), divesting from fossil fuels, and investing in renewable energy projects and sustainable agriculture. And when these types of projects are discussed at planning and zoning and city council meetings, be there to offer support.

Attend the March for Science ( on Earth Day, April 22nd. One of the central goals of this nationwide march is for action on climate change. By a happy accident, I had already planned a trip to Washington, DC for that weekend, so I will be attending the main movement. But I expect them to hold marches in Providence and Boston, so stay tuned for your opportunity to participate.

The last bit of advice I have seems minor, but I think it could stand to be the most powerful. We have to educate people. Our children. Our families. Our friends. We have to tell people that climate change is happening, that it’s because of fossil fuels, and that there are ways we can solve it together. Dispel the myths spread by politicians who don’t understand the science and industries who have a financial gain in denial. The time to act is now.

The Call, Column 65 – The Time to Act is Now!

12 02 2017

(February 12, 2017)

The Urban Farmer

The Time to Act is Now!

Back in December, I wrote a short column describing the basic scientific reasoning behind the fact of global climate change. The gist was this: human activity has thus far released unprecedented amounts of fossil greenhouse gases; this has raised the atmospheric concentration of those gases; they, in turn, are increasing the average global temperature; and within the next century, this warming will result in an ecologically dangerous situation, and a general threat to our comfortable existence on this planet. 1) Climate change IS happening, 2) it’s OUR fault, and 3) the outcome will NOT be fun. But there is a fourth piece to this, and that’s what today’s column is about.

4) We. Need. To. Act. On. Climate. Change. We need to act right now, on every level of action that exists – individual, familial, community, municipality, state, federal, international. Some elements of this action are achievable as individuals, and some by forming relationships with our representatives. But others are much grander, and will take a lot more work by the people smart enough to recognize the problem, passionate enough to want to help, and with adequate means to do so. Those aspects still need to be stated loud and clear, and this column is as good a place as any (or better). So don’t fret when “enact an international climate treaty” isn’t a reasonable thing to put on your monthly to-do list. As a community, a country, a world, and individuals, we will get it done. And here’s precisely how we do it.

We need to stop investing in climate change. Loads of taxpayer and shareholder capital are being irresponsibly dumped in order to prop up a dying energy system; a system based in the exploitation of finite, dwindling fossil fuel resources and the resulting destruction of the local and global environments. Oil and gas pipelines are being built as I write this, by private companies with embarrassing endorsement by our federal government. This infrastructure not only damages local environments, trespasses on protected lands, and poisons people, but encourages the use of the resources that cause climate change and therefore threatens our future.

Not only are private companies literally investing in fossil fuel infrastructure with the government’s blessing, though. The government itself is investing your hard-earned money into causing climate change. Fossil fuels are literally subsidized, of course. But environmentally-destructive projects are approved and endorsed by the government. And the might of the American military is also used – read: soldiers’ lives are sacrificed unnecessarily – to secure steady streams of fossil fuel resources from countries that don’t like us. This direct and indirect subsidization makes fossil fuels appear to be cheaper than they actually are, and keep us as far as possible from feeling financial pressure to adapt to alternative sources of energy.

We need to stop denying science, and start sharing it. This is the 21st century, and the science is beyond settled. Climate change is happening, it’s our fault, and we need to stop it. This is no longer up for debate, especially when the only debate comes from deniers whose logical reasoning is that they own the oil fields or pipelines. As smart, passionate urban farmers, it is our job to make these facts abundantly clear, and expose unscientific climate change denial for what it is: cleverly disguised corporate interest.

Now, I would be lying if I said that the federal government is generally a good source for scientific information. But their climate page ( is a good starting point. Also, the scientists at the EPA, the National Park Service, and NASA regularly share information about the latest climate science via their Twitter and Facebook accounts. Their twitter accounts can be found at,, and, respectively. It is incredibly important, both on the subject of climate change and elsewhere, that information is allowed to flow, unrestricted, between the scientific community and the public. In all countries but fascist regimes like North Korea, the internet is uncensored and allows this to happen.

We need to regulate carbon emissions. This one probably won’t make me any friends, but the future of our planet requires that some form of regulation be placed on carbon emissions. The basic idea is this: the greenhouse gases released by burning fossil fuels (and also clear cutting forests, tilling the land for grain and legume monocropping, and raising animals in feedlots) cause short- and long-term environmental damage. But because there is little regulation on this, that damage is charged to the people, the environment, and the future without needing to be accounted for by the company causing the damage (in economics, this is called a “negative externality”). By implementing a regulation structure, the government (as a representative of the people, the environment, and the future) can “internalize” this negative externality, forcing fossil fuel companies to factor the damage they cause to our climate into their business model.

There have been some ingenious ideas proposed for these much-needed regulations. The first is called Cap and Trade. This is a regulatory structure on the federal level, which basically makes the “right to pollute” into a commodity, whose amount decreases over time. The federal government starts out by limiting the total amount of carbon dioxide pollution that can be released (the “cap”) by the fossil fuel and other related industries, and creates pollution credits, which are essentially commodities that allow the holder to release x-amount of fossil carbon dioxide for one year. These credits are doled out to the applicable companies, and the companies are allowed to buy and sell credits (the “trade”) over the course of the year. This enables companies that make efforts to reduce their carbon pollution – by supplanting fossil fuel power plants with renewable ones, by planting forests, by adopting more efficient technologies or developing better processes – to benefit from this by selling their rights to pollute that they no longer need. Each year, the government ratchets down the total amount of credits (so each company has, say, 98% of the previous year’s credits), and the process continues. This cap and trade system forces the dirtiest, most polluting companies to shut their doors, and indirectly provides a huge incentive for the development and implementation of renewable energies and non-carbon-intensive processes.

Another, much simpler-to-understand solution is a carbon tax. This can be done on a state or even municipal level, and is therefore much more likely to come to fruition in the near future than any action on the federal level. Essentially, any fuel that releases fossil carbon dioxide is subject to a tax on its value, levied on the company that sells it (the gas station, power plant, or electricity distributor). In most versions, the collected tax money is used to fund renewable energy and given directly back to the taxpayers. This is the case with the carbon tax proposed by RI Representative Aaron Regunberg. Studies indicate that his bill’s tax structure would REDUCE energy expenses for the average RI taxpayer (, all while disincentivizing further use of fossil fuels and therefore promoting the use of alternative energies.

We need to fund climate science and subsidize renewable, clean energy sources. This, of course, is the direct result of a carbon tax structure, like the one discussed above. But as a nation, we need to continue to fund research into climate change and renewable energies – allowing scientific organizations like NASA, the EPA, NREL, etc to do their jobs. Because…

Eventually – sooner than we realize – we need to stop using fossil fuels. Every action item in this column points in that direction. Sometime, probably within the next century – but hopefully sooner – and by some economic or environmental pressure – but hopefully before we have no other option – we will no longer use fossil fuels for energy. That is a good thing, a necessary thing. It is the last page in the history book of our exploitive energy economy; the happily-ever-after written long before you or I were born, the moment that a human being burned their first lump of coal. This period in human history can’t last forever; it never could.

It’s going to take action on your part, and on my part, and on our leaders’ parts. It won’t consume our lives, but it’s something we’re going to have to care about. It’s something I hope we already do care about. Next column, we will talk about how to do that.

The Call, Column 64 – It Happens in Iceland

(January 29, 2017)

It Happens In Iceland

Last time, I started to tell you about my trip to the geological masterpiece that is the country of Iceland. I described the geysers and glaciers, volcanoes and black sand beaches, and the waterfalls. The country’s natural beauty is reason enough to talk and write about it, but what I found there inspired me on a much deeper level.

As I started to discuss, the country prides itself on local, sustainable agricultural production. They raise 90% of their own animal products – grass-fed, of course – and 80% of the vegetables that they eat the most, in geothermally-heated greenhouses. All this in part because of a government that has implemented policies that encourage sustainable production, and discourage imports of inferior-quality foods (read: American feedlot meat). As a point of example, the McDonald’s restaurants in the country were forced to close in 2009, because the company’s policy of sourcing its low-quality meat from American, grain-based feedlots instead of Iceland’s local product was against Icelandic law. Iceland kicked out the offender and replaced it with a local chain called “Metro”, effectively rejecting the overtly unsustainable American system and proudly substituting their own.

Because of the weather there, grain is very difficult and resource-intensive to grow, which is part of the reason that they graze their cows and sheep on pasture. They also eat a diet very similar to the one that I follow and have advocated for – plenty of grass-fed red meat and dairy, seafood, vegetables, and some eggs, with very little grains, legumes, sugars, and seed oils. As a result, the population has one of the highest lifespans in the world, with one of the greatest number of people over 100 years of age and an overall low incidence of chronic disease.

Their zeal for self-sufficiency goes way beyond food, as we quickly found out. The country’s freshwater comes from natural, renewable sources – glacial runoff for much of the cold water, and naturally-hot geothermal water for the hot. And they pride themselves on not only a healthful and renewable public water supply, but on being able to drink from almost any natural body of water without fear of contamination.

Their energy sector is no different. Other than gasoline for their cars, Iceland is very nearly self-sufficient in its energy production. Nearly all of their electricity comes from hydropower plants and geothermal generation, and all of their heat energy is geothermal. In fact, geothermal energy is so plentiful in the country, that they freely use it to heat the sidewalks in busy areas so ice does not build up.

Even within the bigger city of Reykjavik, the people have an intimate, affectionate understanding of their country’s food, fuel, and water production systems. It is clear that the Icelandic people take pride in their local products, which is one of their greatest motivators to work towards sustainable self-sufficiency.

Beyond that, though, is their passion for environmental protection and ecological preservation and growth. I described last time how there are not many trees in Iceland. This isn’t because there aren’t any species of trees that are capable of growing there, but with the year-round cool/cold weather, short growing season, and minimal biological exchange with any other landmasses, it’s not easy for forest ecosystems to get a foothold. The people have taken this as a challenge. Experimenting by planting trees is a hobby of many, and a form of volunteering for many others (sponsored, of course, by the government). Their passion for ecological health has actually allowed quite a few stands of evergreens to flourish throughout the country.

The reason, I think, that the Icelandic people are so passionate about environmental health is because they are painfully aware of the effects of global climate change. During our visit to the Solheimajökull glacier, our tour guide explained, in a somber tone, how it was receding…a predictable but very worrying effect of global climate change. Glaciers cover about 11% of the island, and are an important part of the ecological balance – not to mention a primary source of fresh water – in the country. Being an island nation, their ecosystem is particularly fragile, and I worry that increasing global temperatures will throw it completely out of whack. And I think they know it too, which is one of the reasons they care so much about renewable energies.

It’s fitting that, in the 2014 film “Noah”, the last scene where the family wakes up in a post-flood paradise was filmed on a black sand beach in Iceland. The country – from its geological marvels and ecological beauty, to its local and sustainable food, fuel, and water systems, to its kind, pleasant, conscientious people – is like paradise.

They are an almost arctic, island nation, that has nonetheless gotten very close to complete self-sufficiency in renewable energy, renewable agriculture, and renewable water. There are the environmental motivations, of course, and economic ones. But I think that obsession goes a little deeper. The people can see the whole production process laid out before them. They understand raw materials – seafood, pasture grass, fresh water, geothermal heat – to be the products of their environment; and they understand that the “away” where you throw garbage is also another word for “their environment”.

They have no choice but to view economic production as circular, to recognize that, no matter what we do, the environment is the only actual sink, and the only actual source, of every material and good that we use. Production is not linear; it is circular. And by finding renewable, infinitely-sustainable sources, the people of Iceland are able to manage the whole circle in a way that is good for them, good for the environment, and good for the future.

The thing is, we are not Iceland. We don’t have plentiful geothermal energy and uncontaminated waters; we don’t have a government remotely interested in investing in sustainable self-sufficiency, and we aren’t forced to work towards self-sufficiency at any level, because government-subsidized agriculture, trade, and warfare make it appear that resources are plentiful and inexhaustible. But they aren’t. You know that, and I know that, even if our government no longer does.

So maybe we should try to be like Iceland. We have access to plentiful sources of renewable energy – solar, wind, hydropower, and truly sustainable biofuels; we have a small but rapidly expanding sustainable agriculture sector; we have the financial resources to clean up public water supplies and improve our production systems. We may not live on an isolated island nation, but we – as humans – live on a spaceship Earth. This planet is a closed system, driven only by the light from the sun, and we have no choice but to implement production systems similar to Iceland’s if we hope for the Earth to continue to support life.

While we were on a tour of the Southern Coast of the island, our guide Julia was describing a geological process, concluding with, “It doesn’t happen very often in the world, but it happens in Iceland.” The scope of her comment was narrow, but it really punctuated the thoughts that I had had throughout the trip.

Every environmental, and agricultural, and energy-related issue that I care about – and I think you care about too – has a solution. These solutions aren’t always easy, but if we work together, they are achievable. Do you want to know how I know that for sure? While it may not happen in the rest of the world, it already happens in Iceland.

The Call, Column 63 – The Land of Ice and Fire

The Land of Ice and Fire


Faxi (Vatnsleysufoss) Waterfall, Southern Iceland

One week ago, I got back from what, I am now convinced, is the most geologically interesting place in the world. If you’d asked me six months ago where I want to travel in my life, I doubt Iceland would have made the list. But sometime last August, my sister decided that seeing the Northern Lights from the small, almost arctic European country was on her bucket list. She asked if I wanted to go sometime in the coming winter, and I promptly objected. I had big plans – albeit, pretty vague ones – for my vacation time, and it didn’t involve going to a country I knew next to nothing about.

But we are related, and we are Greek, so needless to say she didn’t let up. She sent me picture after picture of the Northern Lights, of course, but also of the extensive list of geological marvels that fill the terrain of the small island nation. And I started doing some research of my own, recalling tidbits I had heart about the culture’s sustainable-meat-based cuisine, their environmental awareness, and their reliance on renewable energies. And so, maybe three weeks later, and much to my surprise, our tickets were booked for the first week of the New Year. But it took until a few days before our trip, while we attempting to plan our itinerary, for me to get really pumped about the journey. And Iceland did not disappoint.

Let me tap the brakes for a second. This isn’t a travel column, and though I’d like nothing more, I’m not writing a Guide to Traveling to Iceland.

Rather, I’m writing this because I went to Iceland looking for natural beauty; and I found not only that, but a people, culture, and government so passionate about every issue and practice that we discuss in this column – sustainable agriculture and self-sufficiency, renewable energy, environmental protection, ecological preservation – that if we all approached life the same way they do, our environmental and agricultural (and probably political) problems would be solved.

First and foremost, the natural, geological beauty of the country is utterly astounding. You can’t drive for five minutes on a road without coming upon something – some river, or rock formation, or farm, or waterfall – that makes you want to stop. Because neither of us had ever been there, we took a couple of guided bus tours. With them, we saw the immense, thundering waterfalls, Gullfoss, Skógafoss, Faxi (Vatnsleysufoss) and Seljalandsfoss, the latter of which grants the wish of any traveler brave enough to venture behind it. We visited the hissing, boiling geothermal area, site of the Strokkur Geyser and the neighboring (currently inactive) Geysir from which the English word originates. We walked on the picturesque, black-sand beaches of Vík and Reynisfjara, with the unforgiving waves of the North Atlantic (almost Arctic) sea on one side, and the looming, volcanic caves of crystallized lava columns on the other.

We walked along the edge of the Keriđ Crater Lake, and stood in the shadow of the infamous Eyjafjallajökull volcano, whose eruption shut down most of Europe’s air traffic in 2010. We made the trek to the immense Solheimajökull Glacier, 600 meters (over 1/3 of a mile) at its tallest, and amid a valley of volcanic ash.  And, much to our unbelievable luck, we saw what was described as the best showing of the Northern Lights the guides had seen that season, in skies that not five minutes before, had been the overcast remnants of the day’s snowstorm. These sights are just the beginning, the major landmarks within one day’s driving distance from Iceland’s capital city, Reykjavik. The country is a naturalist’s dream, but not only for the geology.

Other than a redwood forest in the East, there are few trees in Iceland. The major flora is wild grasses and low-lying shrubbery. And because of its relatively harsh climate, the natural fauna of the country is limited to a few wild species – reindeer, minxes, mice, rabbits, and arctic foxes – along with the country’s farm animals. Most of these species have been introduced relatively recently, either by natural accident (crossing over a land-bridge) or with travelers.

One of the aspects of the country’s culture that really struck me was their passion for resource self-sufficiency. The government has actually – dare I say it – implemented policies to promote self-sufficiency in food, water, and energy. They levy a tariff on foreign imports of low-quality (think: American feedlot) meat and dairy, so the country raises something like 90% of the animals it consumes. And of course, with fishing as their main industry behind tourism, they keep themselves in seafood as well.

They are also incredibly proud of their produce. Geothermal greenhouses allow them to grow around 80% of their tomatoes, cucumbers, and peppers, the vegetables consumed most in the country. The farmers seem to make a sport of their craft, having taken on the challenge of growing more exotic plants like wasabi and bananas – yes, bananas – in their greenhouses.

Having finally hashed out this column on paper, I realize how much I need to say about this amazing country, this dream of urban farmers and environmentalists everywhere. I’ll end today’s column here, and we will pick up next time with more on their agriculture, energy, and environmental relations. Until then, as they say in Iceland, “Bless!”

A Reminder

The Earth’s climate is changing, and human activity is the primary cause.          

            This statement is scientific fact, with no reasonable evidence against it. But it is also a call to action. And with each day that passes, as another 207 billion pounds of carbon dioxide are released into the atmosphere by human activity, it becomes a more dire warning.

Climate change is one of the simplest-to-understand atmospheric phenomena that exist. The Earth’s atmosphere undergoes what is known as The Greenhouse Effect. This is where certain “greenhouse gases”, which make up a small part of the atmosphere, trap the sun’s light as heat, preventing it from escaping back into space and warming the planet in the process. This is directly observable by the fact that you are not currently frozen solid. The Greenhouse Effect holds the temperature of the Earth’s atmosphere stable around 58°F, quite a bit warmer than the -400°F of the surrounding space. It also prevents the temperature from changing significantly (by 100s of degrees) between the day and the night, as it does on the surface of the moon and celestial bodies without Earth’s type of atmosphere.

Despite being present in low concentrations, carbon dioxide has one of the most potent greenhouse gases in the atmosphere. Geological records indicate that the Earth’s average atmospheric temperature has moved in lockstep with its carbon dioxide concentration. This is due to another straightforward chemical mechanism: the molecular structure of carbon dioxide makes it very effective at absorbing heat energy.

Prior to the growth of human industrial activity, the atmospheric concentration of carbon dioxide would change by very, very small amounts, or on a very large timescale, and within a limited range if at all, so that it was effectively constant on a short time-scale, and cyclic on longer ones. There are natural events which produce carbon dioxide – like animals exhaling, decomposition of organic matter, volcanic activity – and those which sequester carbon dioxide – plants inhaling, the formation of topsoil, deposition of fossil carbon within the crust of the earth. In a stable, cyclic system like our Earth’s carbon cycle, these effects naturally balance each other over reasonable periods of time.

This is called a “steady state”, and the same, in fact, is true of the Earth’s atmospheric temperature. While temperature isn’t the same one day (or season) to the next, it has always moved cyclically and predictably; so for example, the temperature in the week around the summer solstice of 1000 BC would be expected to be roughly the same as it had been in 1001 BC, 1025 BC, and 8000 BC. And the same variation in carbon dioxide concentration and temperature is expected – and observed – through every Ice Age Cycle (take a look at this graph: A similar carbon dioxide concentration and temperature occur at the peak of every Ice Age Cycle, and at every trough.

As expected, historically any event that shifted the concentration of carbon dioxide in the Earth’s atmosphere, over any timescale, was met with a similar change in the average global temperature and, as a result, changes in the Earth’s climate.

Burning fossil fuels has increased the concentration of carbon dioxide in the Earth’s atmosphere. This is simple chemistry. When you burn any hydrocarbon – the type of chemicals that make up fossil fuels – it releases carbon dioxide as a direct result of combustion. In the past 150 or so years, we have burned the better part of all the fossil fuel stored beneath the Earth’s crust. The carbon stored in those hydrocarbons was taken out of the atmosphere millions of years ago, when the concentration was higher, the atmosphere was warmer, and the planet had a lot less animals. The Earth has since created a new steady-state with a lower concentration of carbon dioxide. By burning that stored fossil carbon, we are increasing the concentration of carbon dioxide in the atmosphere.

This fact is also demonstrated by empirical observations. Carbon dioxide made up 280 ppm (parts per million) of the Earth’s atmosphere prior to the start of the industrial revolution, and has since increased by over 40%, to 400 ppm. This is likely the highest concentration in the last 20 million years, also shown in that graph I linked to above.

And that increased concentration of carbon dioxide over the past 150 years occurred simultaneously with an increase in average global temperature in the same timeframe.

Let’s review: The Earth’s atmospheric temperature is regulated by the Greenhouse Effect, which is driven by atmospheric greenhouse gases. Carbon dioxide is one of the most important greenhouse gases. Global temperature has historically moved in lockstep with carbon dioxide concentration, which itself has moved cyclically and predictably over large timescales. Burning fossil fuels releases enormous amounts of carbon dioxide, which was out of circulation for long enough that the atmosphere adjusted to its absence. Our use of fossil fuels over the past 150 years has been accompanied with a significant increase in carbon dioxide concentration – a 20-million-year maximum, well beyond natural geological cycles – and a similar increase in average global temperature.

Ipso facto…the Earth’s climate is changing, and human activity is the primary cause. This is the only logical conclusion to all of the evidence we have. And it is bar none the biggest problem we face as a species. The time to act is now.

The Call, Column 35 – Paris ’15: Making the Change We Wish to See in the World

Paris ’15: Making the Change We Wish to See in the World

As you probably already know, last Monday marked the beginning of the 2015 United Nations Climate Change Conference (“COP21”), in Le Bourget, Paris, France. The goal of the conference is to reach a comprehensive, global agreement, in order to reduce greenhouse gas emissions from human activity, and halt the dangerous climate change that these emissions are causing.

Even if a global plan of action is not formed (the U.S. has been a notable holdout in the past), it does not change the facts: the climate has been altered significantly in the past century; we, and specifically our carbon dioxide emissions from the use of coal, oil, and natural gas, are the dominant driving force of that change; and it is easily the biggest threat that we face to the comfortable existence of life on Earth. Moving forward, we can either intentionally take strategic, preventative measures now, or be forced to take reactionary measures to ensure our survival in the future. Given the devastation that is often caused by a single hurricane, I hope it’s clear which action is the safer bet. And today, the engineer (and potential future political leader) in me is going to get really practical: What can we, lowly human beings on an environmentally-unstable planet, do about climate change?

Mahatma Gandhi famously said that you must “be the change that you wish to see in the world” – this is a good starting point. There is action that we can and must take within our own lives, in our own households, to help slow the progression of climate change.

The first step is to assess and minimize your household energy use. In Rhode Island, National Grid and private companies, like RISE Engineering, offer no-cost energy assessments/audits, where they visit your home, assess your energy use, and suggest ways to reduce your long-term consumption. You can find out more about these programs at their websites. And whether or not you get a formal energy audit performed, there are some key areas in home energy use where a small change produces a pretty huge effect. All of these solutions work for commercial buildings as well.

First, lighting uses between 10 and 15% of a normal household’s electricity, and by switching out incandescent light-bulbs for significantly more efficient LED bulbs, you can reduce that amount by 83% – a reduction of nearly 10% of your household’s total electricity consumption, and a savings of about $8.20 per year per bulb. In Rhode Island, we are fortunate that National Grid heavily subsidizes LED lighting, allowing companies like Ocean State Job Lot and many of the drugstores in the area to sell them for around $3 per bulb, yielding a 100% return on investment in as little as four months, on a bulb that will last over 20 years.

Heating, cooling, and refrigeration consume a combined 60% of residential electricity usage. Whether your water heater, refrigerator, air conditioners, and other such appliances are electricity- or gas-powered, there are very efficient versions currently available, which would drastically reduce their energy consumption. And with heavy subsidies from National Grid (, their cost is quickly returned by the savings in energy use. Furthermore, structural efficiency measures (like replacing windows and doors and adding insulation in key areas) can help to reduce heat loss.

In addition, finding ways to supplant current, energy- and carbon-intensive processes with less intensive ones – like switching to a clothes line, or from electric to gas heating – are good ways to reduce your carbon footprint. Also, supplementing or completely replacing fossil fuels with sustainable sources – by having solar panels installed on your roof, or paying a little extra to the energy company in order to guarantee better energy sourcing – may have the biggest effect of all.

Let’s change gears a bit: by driving less, and instead using public transportation, carpooling, and alternate forms of transportation like bicycles, you can significantly reduce your transportation-related carbon emissions. Personally, I take RIPTA whenever I can – on average, one-third to one-half of the times that I go to school in Providence are with public transportation. This and other alternative transportation is often pretty fast, costs less than gas, and doesn’t require parking. Also, because of their efficiency, electric cars (even running on coal electricity) produce less carbon dioxide per mile than gas cars.

Most products that we buy come with baggage, an invisible cloud of carbon dioxide (and other pollution) that was required in order to bring it to your home. By simply buying less stuff, buying used goods (which don’t have an additional footprint), buying locally (to reduce shipping), buying goods whose production methods you know were better for the environment, and throwing away less, you can help to reduce the fossil fuel that is burned by industry on your behalf.

That brings us to a very specific case – the food we eat. The knee-jerk response you’ll hear from some environmentalists is to “eat less meat”, citing a ridiculous, cherry-picked statistic and linking to a tofu recipe. If you couldn’t already guess, I don’t agree with this, and I think it indicates intellectual laziness and unwillingness to look deeper into the issue.

The actual carbon emissions of industrial agriculture come largely from the same place as in every other industry – burning fossil fuels. When industrial grain and soy monocultures are grown year after year, the soil’s fertility must be heavily supplemented with artificial fertilizer – this is made from natural gas, and releases carbon dioxide in its production. Huge amounts of fossil fuels are used in industrial farm machinery and artificial chemical applications. And the off-farm processing of these crops into “food”, and shipping them around the globe, uses fuel as well. When we (unnecessarily and inefficiently) feed animals these cheap grains, the effect is compounded.

Saving more detail for future columns, we need to eat diets that are environmentally-restorative – that have the net, lifetime effect of actually putting carbon into the ground (sequestration) rather than into the atmosphere. That means animal products that are raised on pasture, rotationally-grazed to build the topsoil, and fruits and vegetables that are grown non-intensively, on farms that use organic sources of soil fertility and don’t mechanically harvest, or otherwise in permaculture-type systems.

Buy these foods in season and from your local foodshed to eliminate long-distance transport; and rather than looking for “organic” or “natural”, ask the farmer yourself in order to ensure their practices fit these criteria. And, as always, grow your own using these methods.

We should all certainly make these changes, because they are the most direct and necessary ways to reduce greenhouse gas emissions. But it’s not enough to make them in our own lives, and be satisfied – there are 7 billion other people on Earth, who either already do, or are on the path to, contribute to climate change as much as the average American.

We need to do more than “be the change” – we need to make the change through collective action! We have to champion good politicians who make climate change a top priority. And we have to call and write to make it clear to our leaders (in every level of government) that action on this issue should be taken now, by choice, rather than later, out of necessity.

Whether or not COP21 is successful, we in the United States, with 4.7% of the world’s population that produces an unbalanced 16% of its carbon emissions, need to change our regulatory and legislative climate.

On the municipal and state levels, we need to ramp up incentives for renewable energies – subsidies and grants to consumers who install solar and other alternative energies, the removal of taxes and fees on those projects, and investment by the government itself.

On the federal level, we need comprehensive carbon legislation. Whether that’s a carbon tax on power companies, to incentivize the switch to renewable sources without significantly increasing energy prices, or a cap and trade system, where we catalyze this change through market mechanisms, allowing companies to choose their own paths, or straightforward regulations, directly promoting the use of renewable sources of energy, it has to happen.

We have to stop subsidizing dirty energy. We need to stop sacrificing the lives of our brave servicemen and women in pointless oil wars. We need to stop dragging our feet, entertaining useless politicians who are so blinded by ideology that they are unwilling to spend 1% of our GDP for a few years to ensure that there is a functioning Earth left for our grandchildren.

It’s time to act. In our homes, in our businesses, in our communities; with both our individual and our collective voice, we must demand action before it’s too late. Accelerated climate change threatens the general welfare of life on our planet, and inaction violates the oath that every politician takes to uphold the Constitution. It’s time to act.
