The effects of climate change are incredibly serious, obviously. No one seems to be able to stop the greenhouse Gaussian missions which are causing it. And it's going to have profound effects. One of the less interesting or worse things is that there is a biodiversity crisis now. A number of butterflies is right down, number of moss is right down. The river is not a bad example in England. A lot of the rivers in Britain are polluted. It's a national scandal.
