SAN JUAN, Puerto Rico — A record amount of seaweed is smothering Caribbean coasts from Puerto Rico to Barbados as tons of brown algae kill wildlife, choke the tourism industry and release toxic gases.
More than 24 million tons of sargassum blanketed the Atlantic in June, up from 18.8 million tons in May, according to a monthly report published by the University of South Florida's Optical Oceanography Lab that noted "a new historical record."
