The increase in population from now to 2050 will equal the entire world population in 1950. While the birth rates of developed nations is slowing their populations continue to consume a disproportionate amount of the planet's resources. If our standards of living are to be maintained or improved then this will mean the destruction of much of what remains of the earth's pristine habitats. No one wants that, but still population is hardly ever mentioned by politicians.
