And forests are different:
> Northeast, maple–beech–birch forests
> 25 year old forest: 1,760 lbs of CO2 per acre per year
> Northeast, white and red pine forests
> 25 year old forest: 9,826 lbs of CO2 per acre per year [1]
With global CO2 emissions [2]:
35 billion t / (2000 lbs / acre)
1.561×10^8 km^2 (square kilometers)
≈ land area on the earth ( 1.4912×10^8 km^2 ) [3]
maple–beech–birch forests would not cut.
35 billion t / (10000 lbs / acre)
3.123×10^7 km^2 (square kilometers)
≈ 0.46 × total area of crop land on Earth (2012 estimate) ( ≈ 2.62×10^7 mi^2 ) [4]
pine if used on half of crop land. That's managed forest, no wild forests allowed.
