There’s something to that. In fact, there’s two things to that:
First, trees take carbon dioxide out of the atmosphere (a tree’s leaves “breathe in” CO2).
Second, there’s a lot of room left on the planet to plant trees.
Put those two things together, and researchers at a Swiss university (ETH Zurich) say that if we plant as many trees as we have room for — “Once mature, these new forests could store 205 billion tons of carbon: about two-thirds of the 300 billion tons of carbon that has been released into the atmosphere as a result of human activity since the Industrial Revolution.”
But (you knew that was coming, right?). While nobody disagrees that trees take carbon dioxide out of the air, and that trees are just generally good — after this report came out, there was a lot of back and forth about how many trees we could really plant, and how long would it take those trees to soak up that carbon dioxide, and so forth.
That shouldn’t faze us though. There isn’t going to be a single solution to the potential of global warming. So we can plant trees AND drive in a fuel-efficient way AND cut emissions from our factories — all at the same time. And we should.
But it is nice to know too, that green (as in trees) really is the new Green.
