In the past few decades, Earth's natural systems have endured more pressure than in all preceding human history.

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.

This is a living planet. Look around. Mars, Venus, Jupiter. Look beyond our solar system. Where else is there a place that works, that is just right for the likes of us? It has not happened just instantly. It is vulnerable to our actions. But it's the result of four and a half billion years of evolution, of change over time. And it changes every day, all the time. It would be in our interest to try to maintain a certain level of stability that has enabled us to prosper, to not wreck the very systems that give us life.

The climate has been changing. Of course it [has]. Evidence throughout history, [which] we can assess, especially during human history, shows there have been ups and downs. But the last ten thousand years have been relatively stable compared to now.

Everyone has power. But it doesn't help if you don't use it.

I'm haunted by the thought of what Ray Anderson calls 'tomorrow's child,' asking why we didn't do something on our watch to save sharks and bluefin tuna and squids and coral reefs and the living ocean while there still was time. Well, now is that time.

Like a shipwreck or a jetty, almost anything that forms a structure in the ocean, whether it is natural or artificial over time, collects life.
