If every person on the planet planted one tree, that would be roughly 8 billion trees planted. If everyone planted one tree a year, that would be 8 billion x (# of years lived averaged). If everyone planted a tree a month that would be 8 billion x 12 x (# of years lived averaged). If everyone planted a tree a week that would be 8 billion x 52 x ( # of years lived averaged). If everyone planted a tree a day that would be 8 billion x 365 x (# of years lived averaged). We do not have a economic problem, we do not have a land problem. We have a cooperation problem. Let's cooperate and fix the issues we face. This is a directive to act. Plant a tree. Protect the future.
