Atlantic Ocean’s largest protected marine reserve


Tristan da Cunha, which is inhabited by less than 300 humans is a small chain of islands over 6,000 miles from London in the South Atlantic and the water around the islands are considered to be the richest in the world.

  • The mountainous archipelago Tristan da Cunha is home to tens of millions of seabirds and several unique land birds that are comparable to the Galapagos island finches.
  • However, some of its seabirds that are not found anywhere else in the world face threats including illegal and unregulated fishing activities, overfishing, plastic pollution and climate change. 
  • The National Geographic reported that invasive mice brought to the islands by passing ships kill over 2 million birds a year.
  • As of now, there are two critically endangered species in the island group and over five endangered species.
  • The island group is also home to the World Heritage Site of Gough and Inaccessible Islands, which is one of the most important seabird islands in the world
  • The almost 700,000 square kilometres of the Marine Protection Zone (MPZ) is almost three times the size of the UK and will safeguard the future of sevengill sharks, yellow-nosed albatrosses and rockhopper penguins

As per the National Geographic Society’s Campaign for Nature Initiative, over 30 percent of the world’s oceans need to be protected to allow ecosystems to provide benefits like ample fish stocks.
