Though tiny, these islands are making giant leaps in marine conservation! The isolated UK Overseas Territory of Tristan da Cunha, with a population of just around 300 people, is making great efforts to protect marine biodiversity. The government there declared the largest, fully protected marine reserves in the Atlantic Ocean, covering 6,87,000 square-kilometres!

This covers about 90% of the island’s waters, which will now be free from harmful human activities such as deep-sea mining, sand extraction and bottom-trawling fishing.

Tristan da Cunha is one of the most remote inhabited islands on Earth, and is home to many rare creatures, such as the sevengills shark, the yellow-nosed albatross, rockhopper penguins and more! Now that the government has declared this area a ‘marine protected area’ (MPA), the community will be able to take care of these species and ensure they can live and breed without interference. Interestingly, this MPA is almost three times the size of UK!
