Attenborough's focus on population control as a major solution to environmental problems is well-documented; but this, he recognizes, is not the ultimate way out. "The effects of curbing growth won't be felt for decades," he says. "We have got to face the problem immediately." Education is the key—we have to first understand the "extreme practical reasons to practice environmentalism"—as is a moral realignment: "It wasn't so long ago, especially in your country, that slavery was morally acceptable." As far as Attenborough is concerned, the solution comes down to knowledge—something that, if the politicians and scientists fail to provide, television might tackle. Here, in a way, is where someone like Attenborough steps in.
