I’ll do it, but only if you’ll help


You are reporting the following comment to the PledgeBank team:

Only in the first 10 years of a trees life does in produce more oxygen than it takes in.
But more importantly:
"When a tree dies, it releases its stored carbon back into the air. The death and rotting of one 70-year-old tree would return over 3 tons of carbon to the atmosphere."

The really big O2 producer on our planet is not the tree but the tons and tons of algae in our oceans.
