David Vaughan works on Florida's coral reef stretch, the third longest in the world and one of the most important ecosystems that supports marine life.
Together with a team of scientists he works to combat the destruction of the world's coral reefs (in the last 20 years we have lost 40% of corals due to warming and acidification of the oceans' water).
Vaughan has developed a technique called "micro-fragmentation" which allows corals to grow 25 times faster and restore the habitat of underwater fauna.
Here is a video that illustrates the process and the hope that it can help quickly restore the environmental damage suffered by the ecosystem.
