A writer predicts that in 10 years, the environmental movement will change its mind about population growth, urbanization, genetically engineered organisms, and nuclear power. I think he makes some good arguments. There’s also this, which is news to me:
However, in the 1990s, the U.N. started taking a closer look at fertility patterns, and in 2002, it adopted a new theory that shocked many demographers: human population is leveling off rapidly, even precipitously, in developed countries, with the rest of the world soon to follow. Most environmentalists still haven’t got the word. Worldwide, birthrates are in free fall. Around one-third of countries now have birthrates below replacement level (2.1 children per woman) and sinking.
