YOU reduce, reuse and recycle. You turn down plastic and paper. You avoid out-of-season grapes. You do all the right things. Good.
Just know that it wonâ€™t save the tuna, protect the rain forest or stop global warming. The changes necessary are so large and profound that they are beyond the reach of individual action.
You refuse the plastic bag at the register, believing this one gesture somehow makes a difference, and then carry your takeout meal back to your car for a carbon-emitting trip home.
Say youâ€™re willing to make real sacrifices. Sell your car. Forsake your air-conditioner in the summer, turn down the heat in the winter. Try to become no-impact man. You would, in fact, have no impact on the planet. Americans would continue to emit an average of 20 tons of carbon dioxide a year; Europeans, about 10 tons.
What about going bigger? You are the pope with a billion followers, and letâ€™s say all of them take your advice to heart. If all Catholics decreased their emissions to zero overnight, the planet would surely notice, but pollution would still be rising. Of course, a billion people, whether theyâ€™re Catholic or adherents of any other religion or creed, will do no such thing. Two weeks of silence in a Buddhist yoga retreat in the Himalayas with your BlackBerry checked at the door? Sure. An entire life voluntarily lived off the grid? No thanks.
And that focuses only on those who can decrease their emissions. When your average is 20 tons per year, going down to 18 tons is as easy as taking a staycation. But if you are among the four billion on the planet who each emit one ton a year, you have nowhere to go but up.
Leading scientific groups and most climate scientists say we need to decrease global annual greenhouse gas emissions by at least half of current levels by 2050 and much further by the end of the century. And that will still mean rising temperatures and sea levels for generations.
So why bother recycling or riding your bike to the store? Because we all want to do something, anything. Call it â€œaction bias.â€ But, sadly, individual action does not work. It distracts us from the need for collective action, and it doesnâ€™t add up to enough. Self-interest, not self-sacrifice, is what induces noticeable change. Only the right economic policies will enable us as individuals to be guided by self-interest and still do the right thing for the planet.
Every ton of carbon dioxide pollution causes around $20 of damage to economies, ecosystems and human health. That sum times 20 implies $400 worth of damage per American per year. Thatâ€™s not damage youâ€™re going to do in the distant future; thatâ€™s damage each of us is doing right now. Who pays for it?
