Humans living along Hawaii's coast are negatively affecting nearby green sea turtles, a new report has found.
Agricultural and urban runoff is linked to more tumorous growths on the sea turtles, according to marine biologists at the National Oceanic and Atmospheric Administration, Duke University and the University of Hawaii.

"We're drawing direct lines from human nutrient inputs to the reef ecosystem, and how it affects wildlife," says Van Houtan, a Duke biologist and a scientist with NOAA's Turtle Research Program, in a statement.
Researchers tracked down where green turtles had high rates of fibropapillomatosis, a disease that causes large white tumors to sprout up around turtles' eyes, flippers and armpits.
