Map Reveals Extensive Damage to World's Oceans

Researchers have published a new map highlighting the human impact on oceans worldwide. Their findings show oceans are in serious trouble, with declining fish stocks, disappearing coral reefs and changing water chemistry.

"Our results show that when these and other individual impacts are summed up, the big picture looks much worse than I imagine most people expected," says Ben Halpern, lead author of the paper published in the journal Science.

In a special live broadcast from Boston, Mass. — site of the American Association for the Advancement of Science (AAAS) annual meeting — top ocean experts discuss the prognosis for the world's aquatic ecosystems — and their inhabitants.
