That's ridiculous. No, it has never been disproven. Look around you. So many animals are endangered. We have encroached into nature to the point that many animals can no longer survive. If we do nothing, we will live to see the end of tigers, gorillas and countless others. And it's not just in other countries. When my dad was a kid living ON A FARM, he never saw a deer. Now, we routinely see them in cities. The deer have nowhere to live because we keep building subdivisions and shopping centers in areas that used to be wild.

We need to have far fewer children from now on. Eight billion people is probably about four billion too many. I had two kids. I hope you are not having any.
