One mature tree absorbs 48 pounds of co2 per year link.
Mangroves absorb even more co2 than trees link.
The US Forest service estimates 300B trees in the USA link.
USA produces +/- 5,500,000,000 (5.5B) tons of co2 per year link.
300B trees x 48 lbs = 14.4T pounds of absorbed co2 / 2000 = 7.2B tons of co2 absorbed by trees (not counting any other types of plants or grasses which absorb CO2).
Is that math correct?
Is that a positive net of 75B trees?
One tree, on average, produces 260 pounds of oxygen per year link.
