Taking all these factors into account, the math suggests you’d need somewhere around 50 acres’ worth of trees, planted in tropical areas, to absorb the emissions produced by an average American in her lifetime. Multiply that by the population of the United States, and you get more than 16 billion acres, or 25 million square miles, roughly half the landmass of the world. Those trees would have to be maintained forever. And that’s just for the United States—we haven’t accounted for any other country’s emissions.

Don’t get me wrong: Trees have all kinds of benefits, both aesthetic and environmental, and we should be planting more of them. For the most part, you can get trees to grow only in places where they’ve already grown, so planting them could help undo the damage caused by deforestation. But there’s no practical way to plant enough of them to deal with the problems caused by burning fossil fuels. The most effective tree-related strategy for climate change is to stop cutting down so many of the trees we already have.
