The tiny creature that secretly powers the planet | Penny Chisholm

Oceanographer Penny Chisholm tells the story of a tiny ocean creature you’ve probably never heard of: Prochlorococcus, the most abundant photosynthetic species on the planet. A marine microbe that has existed for millions of years, Prochlorococcus wasn’t discovered until the mid-1980s — but its ancient genetic code may hold clues to how we can reduce our dependence on fossil fuels.

The discoveries awaiting us in the ocean’s twilight zone | Heidi M. Sosik

What will we find in the twilight zone: the vast, mysterious, virtually unexplored realm hundreds of meters below the ocean’s surface? Heidi M. Sosik of Woods Hole Oceanographic Institution wants to find out. In this wonder-filled talk, she shares her plan to investigate these uncharted waters, which may hold a million new species and 90 percent of the world’s fish biomass, using submersible technology. What we discover there won’t just astound us, Sosik says — it will help us be better stewards of the world’s oceans. (This ambitious plan is one of the first ideas of The Audacious Project, TED’s new initiative to inspire global change.)

Let’s turn the high seas into the world’s largest nature reserve | Enric Sala

What if we could save the fishing industry and protect the ocean at the same time? Marine ecologist Enric Sala shares his bold plan to safeguard the high seas — some of the last wild places on earth, which fall outside the jurisdiction of any single country — by creating a giant marine reserve that covers two-thirds of the world’s ocean. By protecting the high seas, Sala believes we will restore the ecological, economic and social benefits of the ocean. “When we can align economic needs with conservation, miracles can happen,” Sala says.
