Studies Show Powerful Benefits of Fully Protected Ocean Areas

New research shows that fully protected areas had 30% more fish species and 2.5 times more fish biomass compared with open areas. It is becoming increasingly clear that humankind must do more to protect our ocean. It generates about half of the planet’s oxygen, regulates our climate, and is home to 80% of all life on Earth. Yet, ocean health is critically threatened by human activities that are driving the collapse of fisheries, the loss of biodiversity, and the acidification of seawater.

There is a growing recognition among political leaders, Indigenous groups, communities, and scientists that governments and other regulatory bodies need to protect and conserve at least 30% of Earth’s coastal and marine areas by 2030 to secure and maintain a healthy ocean...

In the field of marine conservation, a marine protected area (MPA) is an expanse of sea, ocean, estuaries, coastal waters, and in the United States, the U.S. Great Lakes, where fishing, mining, drilling, and other extractive human activity is restricted in an effort to protect the waters’ natural resources and marine life.

Deep-sea corals, for example, which can be up to 4,000 years old, can be damaged by fishing trawls that drag along the ocean floor, scooping up bottom-dwelling fish and crustaceans. By not allowing humans to deplete, disturb, or pollute waterways at will, MPAs discourage such damage to and disregard for sea life...
