Changing Planet

Matt Roush says...

Earth Day is over, but PBS’s “Earth Month” continues with a special from the Changing Planet franchise, now in the third year of a seven-year project to address the Earth’s most fragile ecosystems. The focus turns to coral reef habitats in the Florida Keys and the Maldives which are under threat from climate change, with warming seas causing the corals to bleach and die—in the Keys’ barrier reef, 98 percent of its coral has been lost. The special explores efforts to reverse the alarming trend, including a $100 million reef restoration in a Florida lab that is breeding millions of corals to be replanted on the reef.
