A new study has unveiled humanity's sweeping impact on the world's oceans. Commercial fishing, climate change, agricultural runoff and other human-caused stressors have wiped out nearly 90 percent of Earth's marine wilderness, researchers from the University of California at Santa Barbara and the University of Queensland, Australia revealed.
Just 13 percent of the world's seas can be classified as truly wild, with most being located in the high seas, according to the study published Thursday in the journal Current Biology.
Green Sea Turtles in Australia's Great Barrier Reef are some of the world's most majestic creatures. They have a lifespan of up to 50 years, but after recent results from blood tests on the marine animals, their health might be in jeopardy.
