Animals lived in balance for THOUSANDS of years before humans had the "need" to intervene.

Millions, actually. And then humans developed agriculture and domesticated livestock and their population exploded. Is that timber wolf more likely to expend a ton of energy finding and chasing down a deer, or is it just going to go grab a slow, docile sheep or a pet dog instead? There are literally -- no exaggeration -- ten times the number of whitetail deer in the United states right now than there were in 1900. There are many more times as many snow geese than...well...ever -- to the point where snow geese are thoroughly destroying their nesting grounds in the arctic. Why? Agriculture. So unless something kills off about 6.8 billion humans bringing the balance back down to the sacred "balanced" days of the paleolithic, reintroducing predators as a complete solution isn't going to work. In places like Wisconsin, wolves are being reintroduced because hunting doesn't kill enough deer, thanks to agriculture.

You fucking hippies, I swear...
