  • Mangroves help protect the land from flooding, caused by tropical storms and tidal surges.
  • The Sundarbans in India and Bangladesh are an example of a mangrove forest.
  • Mangroves face a variety of threats including coastal developments, farming and sea level rise.
  • The impacts of mangrove loss include: coastal flooding, loss of biodiversity, resources and income.

Vocabulary To Learn

  • tide: the regular rise and fall of sea levels caused by gravity from the moon and the sun pulling on Earth's oceans
  • tropical storm: a powerful low-pressure weather system that forms in tropical regions
  • tidal surge: an unusual rise in sea level above the normal level of high tide
  • urbanisation: the increase in the proportion of people living in towns and cities rather than the countryside
  • biodiversity: all the living things in an ecosystem or area
