Google turns up a story on NPR that gives some different, larger numbers.
There was one estimate based on satellite images: about 400 billion trees worldwide, or 61 trees for every person.Thomas Crowther and crew spent a couple of years digging up information. When they had added it all up it came to around three trillion trees. Okay, that's good. It's good to have trees. But how does this compare with the good old days? No so good:
But there were doubts about that number because another recent estimate, based on ground-truthed measurements, found 390 billion trees in the Amazon basin alone.
Crowther says their work suggests that, compared with the days before human civilization, the world has lost roughly half its trees. And the gross number of trees lost each year because of humans is now about 15 billion.If that 15 billion trees per year was a constant, then it would have taken us 70 years to cut down one trillion trees and a like amount of time to cut down the the remaining trees. It's not a constant of course. People have been cutting down trees every since some dude came up with the stone ax. We've been cutting down more and more trees every year ever since. We might be approaching peak tree cutting time. If we keep it up trees might become kind of scarce, which means it's going to be harder to find enough trees to cut down so we might not be able to fill our god given quota.
Silent Running Trailer
Reminds me of Silent Running, the goofy Science Fiction movie with Bruce Dern as the custodian of the last remaining forest, which is in a spaceship in orbit around earth because there is no room on earth for any trees because of all the people.
