It makes me suspect that the numbers are off. I found estimate that tree absorbs 20-30kg of CO2 per year. Each cubic meter absorbs 1 ton of CO2. I can't think of any tree grows fast enough for 20 tons. I bet it was originally 20kg not 20 tons.
Which means my estimate is 1000 times small. 1 million sq mi is Argentina. Which means we can absorb some CO2 with trees but there isn't enough land for what is needed.
- otterley 3y ago> I bet it was originally 20kg not 20 tons. I think you're right. Oof, that's a lot of trees. Still worth doing IMO. Keep in mind we can divide by 10 since each tree would absorb approximately 250 kg of CO2 over that period of time. That brings us to about 78,000 square miles or 20M hectares, which seems a lot more feasible.
- tito 3y agoOh you're totally right, 20 kg, not 20 tons. My bad. In a year, 1 tree removes the equivalent emissions of 2 gallons of gasoline.
