More species live in oceans than on land

With increasing human populations and encroaching coastal development, the long-term survival of marine ecosystems - and the many people that rely on them - are under threat. Contributing factors include over fishing, pollution and climate change.

WHY DOES IT MATTER?

Covering more than two thirds of our planet, oceans produce 70% of our oxygen and absorb vast amounts of carbon dioxide. They also drive the Earth's weather systems. More species live in the oceans than on land, including iconic sharks, turtles and whales. The marine environment also holds great economic value, with coastal goods and services contributing a third to Tanzania's gross domestic product.

Did You Know

Tanzania's coastal ecosystem is a home to a wide range of important and valued species including an estimated 150 species of coral in 13 families, 8,000 species of invertebrates, 1,000 species of fish, 5 species of marine turtles and uniquely the whale sharks
