The best scientists and explorers have the attributes of kids! They ask question and have a sense of wonder. They have curiosity. 'Who, what, where, why, when, and how!' They never stop asking questions, and I never stop asking questions, just like a five year old.

Use your power to do whatever it takes to secure for humankind an enduring place on this little blue speck in the universe - our only hope.

We have an atmosphere that is roughly 21% oxygen. The rest of it is largely nitrogen. There's just enough carbon dioxide (CO2) to drive photosynthesis. That has been, throughout the history of our species, pretty stable. Until recently.

Our insatiable appetite for fossil fuels and the corporate mandate to maximize shareholder value encourages drilling without taking into account the costs to the ocean, even without major spills.

We still have 10 percent of the sharks. We still have half of the coral reefs. However, if we wait another 50 years, opportunities might well be gone.

No creature on Earth ever has organized themselves in ways that we have, with the capacity to alter the nature of nature the way we have.
