How Acidification, Overfishing and Plastics Threaten the World’s Oceans

June 8 is World Oceans Day. It’s a fitting time to contemplate humanity’s evolving relationship with the source of all life. For much of human history, we’ve affected marine ecosystems primarily by what we’ve taken out of the seas. The challenge as we encounter warming temperatures and increasing industrial activity will be to manage what we put into them.
World Ocean Day: As the late American marine biologist, author and conservationist Rachel Carson wrote, “It is a curious situation that the sea, from which life first arose, should now be threatened by the activities of one form of that life. But the sea, though changed in a sinister way, will continue to exist: the threat is rather to life itself.”
As a top predator, humans from the tropics to the poles have harvested all forms of marine life, from the smallest shrimp to the largest whales, from the ocean’s surface to its floor.
