St. Thomas, USVI - Not Just a Rock

The U.S. Virgin Islands - St. John, St. Thomas, and St. Croix - were formerly a colony of Denmark and were sold to the U.S. in 1917 for military reasons. Tourism on all three is under threat from coral disease. Earl and Craig follow Dr. Marilyn Brandt and her team of scuba diving scientists who study and combat this threat to coral – known to be the “lungs of the planet.”
