Coral is a living thing, but {{U}}a lot of coral reefs are dying. Some species are considered endangered. Ken Nedimyer is trying to do something about that.

{{U}}Coral reefs worldwide are in decline{{/U}}. {{U}}If coral reefs die completely, coastal communities would be bankrupt, tourism would be virtually gone. A billion people in the world will be impacted{{/U}}. "I started thinking, you know, how can we fix this problem?"
