Just 13% of the Ocean Is Untouched by Humans

Oceans cover approximately 70 percent of the earth's surface, and it seems almost none of that marine expanse is off-limits to adventurous and resource-needy humans.

Just 13.2 percent of the world's seas — or about 20.8 million square miles (54million square kilometers) — remains truly wild, a new study suggests. (For comparison, Asia covers an area of 17.2 million square miles, or 44.5 million square km.)

"Almost all of that wilderness is located in the Arctic, the Antarctic or around remote, Pacific Island nations," study co-author Kendall Jones, a doctoral student at the University of Queensland in Australia and a conservation planning specialist with the Wildlife Conservation Society, told Live Science.
