"Oceans are the source of 70 percent of the world's oxygen and the primary source of protein to over 2 billion people. Covering three-quarters of the earth's surface, this vast resource so vital to human life is imperiled.

But the immediacy of the problem also presents some opportunities. With a little initiative, entrepreneurs and companies can bolster the efforts of advocates by introducing valuable social capital and tools into the equation." (Quoted from article)
