"Green" energy causes forest to be cut down:
You grind up the trees to make wood pellets which count as a "green" "carbon-neutral" energy source. Except the forest is gone (hey, it will grow back in 30 or 40 years, although it will be fast growing pine and fir rather than old growth hardwood - but eggs, omlets, amirite?).
It seems that wildlife has declined by 25%. Yay, environmentalists!
