How do you like this gem of logic by a prominent member, (and candidate in the last federal election), of the Green Party of Canada. The inimitable Erich Jacoby-Hawkins, who actually said that a great many more immigrants would REDUCE our ecological burden by raising urban populations to the point that rapid urban transit would become an economically viable proposition.
Random idea Climate Theory II

"Climate change is not caused by the number of humans, but by unnatural things some of them (okay, most of them) do.
Because of extinctions and reductions in other species, there is not actually more mass of mammalian flesh on the earth, so our respiration and digestion aren't causing global warming. (In fact, total biomass may be at a recent historic low).
However, the fossil fuels that some of us burn in ridiculous amounts, and the forests that others destroy, are definitely culprits. We need to realize that we can exist without burning so much fossil fuel or clearing so much forest. If people live in sustainable, natural ways our contribution to GHG, GW, CC etc. could be reduced to near nil, despite a relatively large human population.
Not easy, of course, but possible."
