Speaking to Radio Times, he also said that China's one child policy wasn't a terrible idea, and that humanity has essentially stopped evolving.
As the Guardian reports, Sir David Attenborough, the famous broadcaster and naturalist, is becoming increasingly outspoken. Earlier this year he described humans as a "plague on Earth." Now he's saying that humans have stopped evolving physically and genetically on account of birth control and abortion; he's basically saying that we've put a halt to natural selection. At the same time, however, he believes that cultural evolution is proceeding with "extraordinary swiftness."
Looking to the future, he says "things are only going to get worse." From the Guardian:
I don't think we are going to become extinct. We're very clever and extremely resourceful – and we will find ways of preserving ourselves, of that I'm sure. But whether our lives will be as rich as they are now is another question.
We may reduce in numbers; that would actually be a help, though the chances of it happening within the next century is very small. I should think it's impossible, in fact.
...I think that in another 100 years people will look back at a world that was less crowded, full of natural wonders, and healthier.
He also told Radio Times about his qualified support for China's one-child policy, saying that "it's produced all kinds of personal tragedies," but that without it there "would be several million more mouths in the world today than there are now."
Personally, I think the greatest threats to humanity comes in the form of existential and catastrophic risks like deliberately engineered pandemics, out-of-control AI, and nanotechnology. Sustainability and population issues don't seem intractable to me, especially given the tremendous potential for renewable energy sources like solar.
And as for humanity not evolving — well, it's true that natural selection barely applies (aside from all the sexual selection that's still going on), but we're about to enter into the transhuman era where we will individually and deliberately re-engineer ourselves using a combination of nanotechnology, biotechnologies, information technologies, and cognitive science.
Our current biological state is just the beginning.
