Earth as an ecosystem stands out in the all of the universe. There's no place that we know about that can support life as we know it, not even our sister planet, Mars, where we might set up housekeeping someday, but at great effort and trouble we have to recreate the things we take for granted here.

Why does evolution matter? There is so much about the evolution of life, the development of life on Earth that should rivet the attention of everyone to understand where we've come from and where we might be going. We need to understand the world around us if we are to succeed as a species on the planet.

We need to respect the oceans and take care of them as if our lives depended on it. Because they do.

No water, no life. No blue, no green.

What we put into the atmosphere in terms of burning fuel is unprecedented.

If you make the choice to just go with the flow, that is a choice to make a difference in a negative way.

With care and protection, with safe havens in the ocean, there is still a good chance that we can turn things around.
