Here are some amazing facts about our oceans.

70 Percent of the Earth’s surface is covered by oceans.

1 Percent of the Earth’s oceans are protected.

1 billion People worldwide depend on the ocean as their main source of protein.

52 Percent of the world’s fisheries are fully exploited. Another 20 percent are moderately exploited, and 19 percent are over-exploited.

3/4 Of tropical commercial fish depend on mangrove forests for food, habitat, breeding or nursery grounds.

Up to 35 Percent of the world's mangrove forests have been destroyed in the last 30 years.

1,400 Pounds - potential weight of a northern bluefin tuna. Top predators like this one are vital to the ocean food chain.

90 Percent of large predatory fish populations—including cod, shark and bluefin tuna—have disappeared worldwide due to unsustainable fishing practices.

1 in 4 Of all marine species live in coral reef ecosystems. (It’s no wonder reefs are often called "the tropical rainforests of the ocean.”)

20 Percent of the world’s coral reefs have been lost to date. Another 20 percent are degraded.

70-80 Percent of the oxygen we breathe is produced by the ocean.

150,000+ Is the combined size in square miles of pollution-caused "dead zones"—marine habitats that no longer support oxygen-using species. That’s larger than the state of Montana.

97 Percent of all water on earth is located in the planet’s oceans.

1 The number of "blue planets" called Earth.
