Trillions, Not Billions Of Trees

I'm not surprised at all.
“Trees are among the most prominent and critical organisms on earth, yet we are only recently beginning to comprehend their global extent and distribution,” said Crowther. “They store huge amounts of carbon, are essential for the cycling of nutrients, for water and air quality, and for countless human service,” he added. “Yet you ask people to estimate, within an order of magnitude, how many trees there are and they don’t know where to begin. I don’t know what I would have guessed, but I was certainly surprised to find that we were talking about trillions.”
Later in the article the author mentions that we cut down 15 billion trees and only plant 5 billion replacements.  But, trees aren't cows.  We don't artificially inseminate trees to make more trees.  Tress are more than capable to reproduce themselves.  Just because a human isn't there to see a new tree grow doesn't mean it doesn't happen.  I dare say, many billions more grow from seedlings with no human help at all in planting.
