On 25 July 2020, Japanese-owned bulk carrier MV Wakashio ran aground on a coral reef off the coast of Mauritius, leaking up to 1,000 tonnes of heavy oil into a pristine lagoon. Its location on the edge of protected fragile marine ecosystems and a wetland of international importance made the ''MV Wakashio'' oil spill one of the worst environmental disasters ever to hit the western Indian Ocean.
