their wings. with stiff wings, they can roll theirwings. somehow, with stiff wings, they can roll their wings. somehow, we don t know how they flex their wings, but they can curve them as they fly, and that means that they can effectively swim through the air and push the air backwards, a bit like you do in a swimming pool when you swim. but this research has really shown us how they have got the evolutionary edge, because a lot of things out there want to eat butterflies, birds and so on, and this clamping mechanism gives them the thrust that gives them a bit of a speedy, jerky flight, and of course for a bird that makes them a bit more difficult to catch, so that gives them one up on the birds. to catch, so that gives them one up on the birds- on the birds. have you been mesmerised on the birds. have you been mesmerised by on the birds. have you been mesmerised by them i on the birds. have you been mesmerised by them for i on the birds. have you been i mesmerised by them for man

planet and the way they‘re interconnected and the services they provide for us, if you like, clean water, clean air, food, medicines. and we‘re having report after report talking about the crisis, the term some years, in nature at the moment. report on the last few weeks reporting that global wildlife populations have declined by two thirds since the 1970s. and a techie to targets that governments signed up to targets that governments signed up to in 2010 executive targets. the un reported back on those on those targets to protect nature, none of them had been met in full. there have been some individual su ccesses there have been some individual successes in individual countries, small successes, but none had been met in full. so it‘s against this backdrop really that we‘re seeing
