Doesn't matter. In 50 years the planets population will have doubled. 14 billion...... If we make it that far. Don't think the planet can support thatThe world is changing. We can't go back to loin cloths and knapping points to hunt with.
We have had huge projects stopped by trying to preserve the spotted owl.
Now they are killing the spotted owl's because they are predators of other owls!
The dammed snail darter minnow was a huge issue.
There are thousands of specie that go extinct every year by natures hand. Man causes some, but when does a minnow make a difference?
