Most of the southern hemisphere is unexplored. We had more exploration ships down there during Captain Cook's time than now. It's amazing.

I love all of the Earth.

Remember to always dream. More importantly, work hard to make those dreams come true and never give up.

You can only inspire when you give people a new way of looking at the world in which they live.

The fact that this chain of life existed [at volcanic vents on the seafloor] in the black cold of the deep sea and was utterly independent of sunlight - previously thought to be the font of all Earth's life - has startling ramifications. If life could flourish there, nurtured by a complex chemical process based on geothermal heat, then life could exist under similar conditions on planets far removed from the nurturing light of our parent star, the Sun.

There are more active volcanoes beneath the sea than on land by two orders of magnitude.
