What is Wetlands and Coasts?
Within Earth & Environmental Science, which covers our planet, its resources and ecosystems, and how people can protect the environment, this topic explains Wetlands and Coasts. Earth and environment topics show how the planet’s systems shape landscapes, climate and life, with models that make these processes visible.
Check that you can explain Wetlands and Coasts in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Wetlands and Coasts helps you explain the environment around you and weigh up how people can protect it.
Wetlands and Coasts in detail
Wetlands, such as marshes, swamps, peatlands, mangroves and estuaries, are areas where water covers or saturates the soil. They are among the most productive ecosystems, acting as nurseries for fish, habitats for birds, natural filters that clean water, stores of carbon (especially peat) and buffers that absorb floods.
Coastal ecosystems, including beaches, dunes, salt marshes, mangroves and rocky shores, protect land from erosion and storms. They are threatened by drainage for farming, development, pollution, sea level rise and tourism pressure. Protection includes the Ramsar Convention, restoration and sustainable management, because their loss reduces biodiversity and flood protection.
