Africans vs Americans
The average North American needs 14 times as many trees to absorb the CO₂ emissions (primarily from burning fuels) as does an African. The USA thus has the population equivalent of 4.3 billion Africans when it comes to global warming. The scary part is, much of the third world are learning to live like Americans too — the net effect is like a lethal population explosion. The really scary part is we have nowhere near enough trees even as it is and we are killing them off at an unprecedented rate.
