Why we need a healthy ocean

by Kathlyn Tan

The ocean is one of our most important resources, yet for decades our actions have caused incredible harm. So the next time you enter into a conversation with someone about the environment, here are four key reasons why we need a healthy ocean.

The air we breathe

Scientists believe that the ocean produces more than 50% of the world's oxygen. Oxygen is produced by marine photosynthesisers, such as phytoplankton, kelp and seaweed.

Climate regulation

The ocean makes up 71% of the Earth’s surface. It transports warm water and precipitation from the equator toward the poles, and cold water from the poles back to the tropics, regulating our climate and weather patterns. It is also the planet’s greatest carbon sink, storing 50 times more carbon dioxide than our atmosphere and 90 percent of the surplus heat energy retained in Earth's climate system due to excess greenhouse gases.

Food security

According to WWF, seafood is the largest traded food commodity in the world. Approximately three billion people rely on both wild-caught and farmed seafood as their primary source of protein.

Blue economy

Over 300 million livelihoods are dependent on a healthy ocean for fishing, aquaculture, tourism, etc. The World Bank reports that more than US$190 billion of global annual revenue comes from seafood; and est. US$161 billion from marine and coastal tourism.

Water is life, and yet the seas which we depend on to survive are in peril. Today, our ocean is at risk from pollution, overfishing, global warming, ocean acidification and habitat loss:

Fish stocks

90 percent of fish stocks have been fully exploited, overexploited or depleted. Read this article by the World Economic Forum.

Sharks & rays

36 percent of sharks and rays are threatened with extinction. Read this article by World Wide Fund For Nature.

Coral reefs

50 percent of corals have been lost in the last 30 years. Read this article by National Geographic.

Plastic pollution

11 million metric tons of plastic enters the ocean each year. Read this article by Pew.
