Blue Planet: Coasts
Some of the most productive and biologically rich areas on Earth
Not only do these ecosystems support a huge variety of life, many also serve as nurseries for much of the biodiversity of the entire oceanic system. These ecosystems also help protect coastal land from erosion due to storm surges and other large waves, such as tsunamis.
The coast also has a huge influence on people. According to the UN, around 3.6 billion people, or 60% of the world’s population, live within 60km of the coast. And 80% of all tourism takes place in coastal areas. Most of the goods we extract from the ocean - from fish to oil and gas - come from coastal regions. Coastal ecosystems also provide a range of services that benefit people around the world.
