A good article on the effects of going “green” by using ethanol.
Corn requires WAY MORE water and fertilizer than other crops. Fertilizer that ends up as unwanted nutrients in the rivers, lakes, and ocean. All sorts of other problems with ethanol of course.
You posted an article from the Union of Concerned Scientists. A radical leftist environmental group.
