It would help if these idiots would just quit trying to manipulate nature. Many years ago these same idiots decided to intraduce mountain goats to the olympic national park because some sort of shrub was taking over at higher elevations. Goats took care of that problem plus ate everything else they could find destroying all the ground covers and leading to the landscape getting washed away by rains because the ground cover was gone. They were talking about introducing wolves to take out the population of goats.
These people are just educated idiots. Just because they went to college and read a book they think they have the answer. The problem with college is if you're an idot going in your still going to be an idiot coming out.
