FYI, 99% of ALL species that EVER existed on this Earth are now extinct.
Furthermore, at what cost should the protection of species be? The extinction of humans?
that's the same logic that tree-huggers use to say that hunters are evil.. whereas the reality is that conservation groups (also known as rod & gun clubs) do the vast majority of grassroots support for wildlife, and certain species of animals are propagating specifically through the help of those organizations
often the facts go against common logic.. such as the case with the Alaskan pipeline.. critics argued that it would destroy the environment and animals would suffer.. in reality, the pipeline has provided protection and refuge for many species.. the caribou population has exploded since it was built
with a few known exceptions (passenger pigeons, bison, etc), man has done at least as much for the welfare of animals as he has done to hurt their species.. I for one, do not feel it necessary to take on the guilt of various extinctions.. the rule of nature is either adapt or become extinct.. man has to follow that same rule.. why should animals be put above us?
