Hey, there's 40% left looks like agent orange may complete the task.

That's why Greenpeace and wildlife conservancy organization exist

It was put very simply by author Daniel Quinn. Look on the environment as a huge brick wall. Every time we kill a species, be at animal, plant, insect or anything else it is like removing a brick from the wall. We can go on doing this year after year with no obvious effect until one day we remove a brick and the whole wall collapses.I am sure we are a long way from this but keep going on the way we are doing and it could happen eventually.

wildlife thrives in areas where humans are excluded, even in the fallout area around chernobyl.... the solution is simple set aside large areas of the planet

Humans really suck. We do what is expedient to us with no regard for the living planet we live on.
