The Great Barrier Reef is 1,800 miles long and home to a quarter of the world's ocean species. So it's no wonder that marine biologists, fearing its pollution-driven demise, started freezing corals so they can preserve them for later.
Scientists have found dead and dying coral reefs 4,500 feet deep in the Gulf of Mexico. The dead coral means that oil from the BP oil spill is harming marine life in the deep ocean too.
It might look a bit creepy, but British artist Jason de Caires Taylor's Mexican installation and reef conservation project is for a fine cause. Taylor has 350 statues in place—all cast from real people—that will eventually sprout coral.
Sure, coral reefs are pretty, but they also have creepy almost alien-like superpowers: An entire reef can be regrown from a tiny chunk of coral.
