The following are excerpts from Michael Pollan’s now classic essay “Why Bother?” – first published in the New York Times Magazine in April, 2008. For the entire essay, go to Why Bother?

Why bother? That really is the big question facing us as individuals hoping to do something about climate change, and it’s not an easy one to answer. I don’t know about you, but for me the most upsetting moment in “An Inconvenient Truth” came long after Al Gore scared the hell out of me, constructing an utterly convincing case that the very survival of life on earth as we know it is threatened by climate change. No, the really dark moment came during the closing credits, when we are asked to . . . change our light bulbs. That’s when it got really depressing. The immense disproportion between the magnitude of the problem Gore had described and the puniness of what he was asking us to do about it was enough to sink your heart.
There are so many stories we can tell ourselves to justify doing nothing, but perhaps the most insidious is that, whatever we do manage to do, it will be too little too late. Climate change is upon us, and it has arrived well ahead of schedule. Scientists’ projections that seemed dire a decade ago turn out to have been unduly optimistic: the warming and the melting is occurring much faster than the models predicted. Now truly terrifying feedback loops threaten to boost the rate of change exponentially, as the shift from white ice to blue water in the Arctic absorbs more sunlight and warming soils everywhere become more biologically active, causing them to release their vast stores of carbon into the air. Have you looked into the eyes of a climate scientist recently? They look really scared.
So do you still want to talk about planting gardens? I do.
….the act I want to talk about is growing some–even just a little–of your own food. Rip out your lawn, if you have one, and if you don’t–if you live in a high-rise, or have a yard shrouded in shade–look into getting a plot in a community garden. Measured against the Problem We Face, planting a garden sounds pretty benign, I know, but in fact it’s one of the most powerful things an individual can do–to reduce your carbon footprint, sure, but more important, to reduce your sense of dependence and dividedness: to change the cheap-energy mind.
A great many things happen when you plant a vegetable garden, some of them directly related to climate change, others indirect but related nevertheless. Growing food, we forget, comprises the original solar technology: calories produced by means of photosynthesis. Years ago the cheap-energy mind discovered that more food could be produced with less effort by replacing sunlight with fossil-fuel fertilizers and pesticides, with a result that the typical calorie of food energy in your diet now requires about 10 calories of fossil-fuel energy to produce. It’s estimated that the way we feed ourselves (or rather, allow ourselves to be fed) accounts for about a fifth of the greenhouse gas for which each of us is responsible.
Yet the sun still shines down on your yard, and photosynthesis still works so abundantly that in a thoughtfully organized vegetable garden (one planted from seed, nourished by compost from the kitchen and involving not too many drives to the garden center), you can grow the proverbial free lunch–CO2-free and dollar-free. This is the most-local food you can possibly eat (not to mention the freshest, tastiest and most nutritious), with a carbon footprint so faint that even the New Zealand 
lamb council dares not challenge it. And while we’re counting carbon, consider too your compost pile, which shrinks the heap of garbage your household needs trucked away even as it feeds your vegetables and sequesters carbon in your soil. What else? Well, you will probably notice that you’re getting a pretty good workout there in your garden, burning calories without having to get into the car to drive to the gym. (It is one of the absurdities of the modern division of labor that, having replaced physical labor with fossil fuel, we now have to burn even more fossil fuel to keep our unemployed bodies in shape.) Also, by engaging both body and mind, time spent in the garden is time (and energy) subtracted from electronic forms of entertainment.
You begin to see that growing even a little of your own food is, as Wendell Berry pointed out 30 years ago, one of those solutions that, instead of begetting a new set of problems–the way “solutions” like ethanol or nuclear power inevitably do–actually beget other solutions, and not only of the kind that save carbon. Still more valuable are the habits of mind that growing a little of your own food can yield. You quickly learn that you need not be dependent on specialists to provide for yourself–that your body is still good for something and may actually be enlisted in its own support. If the experts are right, if both oil and time are running out, these are skills and habits of mind we’re all very soon going to need. We may also need the food. Could gardens provide it? Well, during World War II, victory gardens supplied as much as 40 percent of the produce Americans ate.
But there are sweeter reasons to plant that garden, to bother. At least in this one corner of your yard and life, you will have begun to heal the split between what you think and what you do, to commingle your identities as consumer and producer and citizen. Chances are, your garden will re-engage you with your neighbors, for you will have produce to give away and the need to borrow 
their tools. You will have reduced the power of the cheap-energy mind by personally overcoming its most debilitating weakness: its helplessness and the fact that it can’t do much of anything that doesn’t involve division or subtraction.
The garden’s season-long transit from seed to ripe fruit–will you get a load of that zucchini?!–suggests that the operations of addition and multiplication still obtain, that the abundance of nature is not exhausted. The single greatest lesson the garden teaches is that our relationship to the planet need not be zero-sum, and that as long as the sun still shines and people still can plan and plant, think and do, we can, if we bother to try, find ways to provide for ourselves without diminishing the world.
