      Coastal habitats and ecosystems

      Lesson details

      Learning outcome

      I can identify some threats to coastal habitats around the world and explain why these places matter to wildlife.

      Key learning points

      1. Coastal habitats and their unique ecosystems are under threat from human activity and climate change.
      2. Coastline settlements and industries impact on natural habitats affecting wildlife populations.
      3. River estuaries can be hot spots of pollution emptying into the oceans.
      4. Eco-tourism is a way of trying to redress environmental damage by focusing on outcomes beneficial for wildlife.

      Keywords

      • Ecosystem - An ecosystem is a natural environment and the plants and animals live and interact within that environment

      • Habitat - Habitat is the natural home or environment of an animal, plant or other organism

      • Pollution - Pollution is anything that makes the environment dirty or unhealthy

      • Organism - An organism is a living thing

      Common misconception

      Nature reserves or world heritage sites only apply to places on land.

      Many coasts and underwater ecosystems are classed as Marine Protected Areas and are protected in the same way as nature reserves.

      Teacher tip

      As an extension activity, children could investigate if the coastline nearest to them has been affected by climate change, pollution, farming and fishing or tourism. Or they could locate the MPA closest to them.
