Over the years, Cody Clements, a marine ecologist at Georgia Tech, has planted over 10,000 coral fragments across the South Pacific.
"You can just break off a branch from a coral, plant it into the sandy bottom, and it will grow into a whole new coral," explains Clements. "I have corals out there that I've planted and they were the size of my pinky — and now they're the size of a basketball."
