Plenty Of Fish In The Sea? Not Quite.

A major warning today about the state of the world's oceans. A new report says marine life is on the brink of mass extinction. The study was done by the International Programme on the State of the Ocean and will be presented to the United Nations. It says we are on the verge of losing entire ocean ecosystems and species within a single generation, because of climate change, pollution and over-fishing.

The report says if we don't take action now, we'll destroy coral reefs, wipe out marine species, and create low oxygen "dead zones" in our oceans. The study says over-fishing is the easiest for governments to reverse. It's believed over-fishing accounts for more than 60 per cent of the extinction of marine fishes.

Of course, it's difficult for most people to understand how devastating over-fishing is, because we can't see the damage it's causing. But when you visualize the research data, the picture isn't pretty. Many of the most popular fish to eat (bluefin tuna, cod, haddock, hake, halibut, herring, mackerel, pollock, salmon, sea trout, striped bass, strugeon, and turbot) are either vulnerable or endangered.

This infographic gives you a good idea of how severe the situation is. It shows what things were like in 1900 and in 2000.
