It's too late to be a pessimist.

It's too late to be a pessimist.


Our impact on Earth has grown enormously.  So much so that humans are now a geologic agent.  We move as much material every year as all the rivers, including their tributaries.  For the last 25 years, we've done that.  And the pace is increasing.

We must make substantial changes in how we "use" the planet, else become extinct.
