How many birds are killed by house cats and cars every year? Of course one needs to keep investigating how to make windmills more bird-friendly. The solar plant which killed birds is a solarthermal one which concentrates the sunlight via mirrors. Photovoltaic plants do not kill birds. France has a good history of running their plants, but they do get older. So the risk is constantly raising. I am living in Bavaria, Germany. Here is is still not considered entirely safe to eat mushrooms and wild boar from the forests, as they still carry contamination from the Chernobyl incident, and are expected to do so for the next decades. And Chernobyl is about 1000 km away from here.
