The human capacity for making other species go extinct makes us look like a virus imo
I read something about when human's (ancestors to indians) came to America thousands of years ago... It was a neat article.. Anyways, when humans start appearing in the fossil record in America, their appearance is followed by the extinction of the large mammals, such as mammoths, giant bison, etc. Virtually all the really large things that were around became extinct.
The people that came over were big game hunters... we have found tons of projectile points associated with the fossils. Therefore, the animals more or less were hunted to extinction by people that didn't know any better. (Me hungry.. me kill big things.. they ez to hunt not run like rabbit.. lots of food) I don't think it was totally the fault of humans that the animals became extinct. The climate was becoming warmer which probably added more pressure to the animals, but still...
We also killed off the passenger pigeon in the early 20th century, due to OVER hunting and clearing their habitat for our agriculture. At one time it was the most numerous bird in the world (population estimates from the 19th century ranged from 1 billion to close to 4 billion)
Then there is the current situation with mountain gorillas.. they'll be going extinct probably in the next decade or so. Loss of habitat is a big thing for a lot of animals. Then, there are the numerous deforestations of our rain forests going on around the world... who know's what all we're killing off so we can have farm land or paper...
