The broadcaster and naturalist Sir David Attenborough says scientists and environmentalists have been cautious of overstating the dangers of global warming, but recent evidence of melting polar caps shows the situation is worse than had been thought. He also discusses population growth and disappearing habitats

Attenborough said he thought the U.S.’s attitude towards climate change and the environment was not just because of politics, but because of the country’s history. “[It’s] because they’re a pioneer country. There has been the wild west, the western frontier … that’s still there. You see it in the arms business, the right for everyone to bear arms. It’s part of the pioneer stuff that [Americans have] grown up with.”
By contrast, he said, people in the U.K. had “grown up with a mythology of black industry and wrecking the countryside.”
The current financial crisis has made it problematic for politicians to show leadership on climate change, Attenborough acknowledged. “Well, it’s a very difficult time to do it. In times of recession, it’s a very difficult time to advance these arguments [on the urgency of tackling climate change] that mean you have to spend even more money and take money from taxes to do things,” he said.
Yet he also warned that it was becoming clear the impacts of climate change were worse than had been expected. Talking about the record Arctic sea ice melt this summer, he said: “The situation is worse than we thought [in the Arctic]. The processes of melting are more volatile than we thought. More complicated. The ice cap is really melting faster than we thought.”
The 86-year-old naturalist, who is also a patron of the charityPopulation Matters, said many of the environmental problems the world faced could be helped by addressing human population, which isbelieved to have reached the 7 billion mark last year, and is forecast to reach 10 billion by the middle of the century.
The solution, he said, was to raise living standards and increase democracy in developing countries. “The only way I can think of [tackling population] is by giving women the rights to control their own bodies and control how many children they have. In every circumstance where women have that right, where they have the vote, where there are proper medical facilities, where they are literate, where they are given the choice, the birth rate falls,” he said. “That is a good start, if that could be spread.”
