“It presents our greatest challenge. Humanity’s future will not be discovered on the surface of Mars, but in that 99.9 percent of the Earth’s oceans that remain a mystery. And we neglect it at our peril. The oceans are our breadbasket, our playground, even our pharmacy. More importantly, the seas are the true lungs of our planet, producing 80 percent of the world’s oxygen and consuming 25 percent of the carbon dioxide. If even a quarter of the ocean dies, so does most life on Earth.”
