Hawaii’s golf courses and pineapple farms are causing tumors in imperiled green sea turtles, a study published Tuesday finds.  The link is an amino acid called arginine, which trickles down from the island’s nutrient-rich urban runoff into the turtle’s food source, riddling their bodies with white tumors.  “We’re drawing direct lines from human nutrient inputs to the reef ecosystem and how it affects wildlife,” said Kyle Van Houtan, lead researcher on the study, in a statement.
