The ocean may be our best hope in fighting the climate crisis -

 — but it needs our help.

 

Due to its vast expanse, the ocean is able to capture at least 25% of the carbon dioxide released by humans into the atmosphere.

 

The underwater world beneath the waves can trap carbon for thousands, and perhaps even millions, of years. This "blue carbon" is far more efficient than the carbon captured by plants and trees. 

 

But such an impressive capacity can't be expected to continue without protecting the sea itself, said experts participating in CNN's Call to Earth Day on Thursday. Scientists suggest preventing fishing and mining in large areas of the ocean, restoring ecosystems like coral reefs and preventing pollution from entering waterways.

 

If the warming ocean in its current state is able to do its part in saving the planet, a healthier ocean could make an even greater impact, experts believe.  The ocean is full of hope. Just ask the Queen of the Deep, Sylvia Earle

The 87-year-old oceanographer has spent much of her life exploring the ocean and still holds the world  record for the deepest untethered walk on the seafloor. "Every time I go into the water, I see things I've never seen before," she said. Her Mission Blue program, which supports research and restoration of the ocean, has  identified more than 140 marine areas around the world that are critical in revitalizing  the ocean. Designated as Hope Spots, these special sites are guarded by local communities and institutions.
