Despite the oceans' vast expanse across 70 percent of the Earth, their every reach is affected by human activities, a new study by researchers at the University of North Carolina at Chapel Hill and others says.

The study, published today in the journal Science, says that over 40 percent of the world's oceans are suffering from multiple human influences, including overfishing, pollution, climate change and commercial shipping traffic. And no part of the deep blue sea is entirely unaffected, the scientists found.
