"On a former Cold War missile base perched high above the Golden Gate Bridge, in what is now the largest marine mammal hospital in the world, Frances Gulland still remembers the shock she felt when she first started working here as a veterinarian 26 years ago.
A male sea lion had washed ashore in severe pain. His hind flippers were swollen, his lymph nodes riddled with tumors. Cancer had taken over his kidneys and turned his spine to mush. First responders at the Marine Mammal Center told Gulland they saw this in sea lions all the time.
“Wildlife should not be getting cancer like this, that’s crazy!” said Gulland, who was new to California. “How can that be?”
Now, after two decades of study, an all-star team of marine mammal pathologists, virology experts, chemists and geneticists say they’ve connected two surprising culprits: herpes and toxic chemicals, like DDT and PCBs, that poisoned the California coast decades ago."
