One thing for sure.....

The single most significant thing that can be done for the environment, for the animals, for all that live on the earth is to reduce the number of humans on the planet. There are way more than twice as many people in the US than there were when I was born, and I assure you life is not twice as good. It has been going in the other direction. We would be wise to provide a tax credit for those that choose to remain childless, however I will not hold my breath waiting for wisdom to kick in. In fact, were we an honorable people, considering what we did and do to the folks that really own the country we would have no more children....none. And when a family died out, what they own would revert to the ancestors of the original inhabitants.....such would be the honorable thing to do, I will not hold my breath waiting for that either.
