An ambitious program to restore seven coral reefs in the Florida Keys has received a $3.5 million donation from the United Arab Emirates, the non-governmental United Way organization, which will administer the funds, announced on Wednesday.

The United Way chapter in Florida's Collier County and in the Keys said in a statement that the donation will be used for the 20-year "Mission: Iconic Reefs" program and is "one of the largest investments in reef restoration anywhere in the world."
