Bats

This YouTube video is an important one to watch, not just because of what happens to the bats, but also because of the horror that is being done to some stunning landscapes in Oregon.
Much is made in the commentary of fact that wind turbines are "clean energy" - what about the environmental damage caused by mining for rare earths in China, used in wind turbines, for a start? That is not very clean.
Incidentally, you can hear the turbine noise, and see the shadow flicker, although they do not comment on that.
