Could it be too late to save the global ocean, which covers 70% of the earth’s surface? When you tally up all the environmental damage from a variety of causes it’s not hard to conclude by the end of this century the ocean will be unable to support the vast diversity of life we have come to associate with it.

Instead of shellfish, whales, and tuna, it will be teeming with algae and jellyfish.

Plastic? You might how this could be a major problem until you realize the average consumer in an industrialized country uses 250 pounds every year.

The United Nations Environment Programme estimates that currently 46,000 pieces of plastic are floating on every square mile of the ocean.

The problem in the Pacific is so severe a humongous plastic-strewn patch floats between California and Hawaii within the North Pacific Gyre.
