But most of the 7 billion are not endangering the earth. The majority of the world’s people don’t destroy forests, don’t wipe out endangered species, don’t pollute rivers and oceans, and emit essentially no greenhouse gases.

No reduction in U.S. population would have stopped BP from poisoning the Gulf of Mexico last year.
Lower birthrates won’t shut down Canada’s tar sands, which Bill McKibben has justly called one of the most staggering crimes the world has ever seen.
Universal access to birth control should be a fundamental human right — but it would not have prevented Shell’s massive destruction of ecosystems in the Niger River delta, or the immeasurable damage that Chevron has caused to rainforests in Ecuador.
