Warming and acidification from carbon dioxide in our atmosphere are having long-term effects on life in our oceans. In this video from
Earth Vision Trust, marine ecologist and geologist Joanie Kleypas, of the National Center for Atmospheric Research, explains how carbon dioxide changes the pH level of the ocean and how that leads to coral die-off. She also helps us understand how humans can help restore damaged coral reefs.
Earth Vision Trust is a nonprofit founded by National Geographic photographer and grantee James Balog that seeks to educate and inspire the public through innovative visual exploration of the changing environment.
The
Short Film Showcase spotlights exceptional short videos created by filmmakers from around the world and selected by National Geographic editors. We look for work that affirms National Geographic's belief in the power of science, exploration, and storytelling to change the world. The filmmakers created the content presented, and the opinions expressed are their own, not those of National Geographic Partners.
