Saudi endurance swimmer and dentist Mariam bin Laden swam from Saudi Arabia to Egypt, becoming the first Arab and Saudi woman to achieve such a feat.
Despite the threat of sharks, she swam across the Red Sea to reach the COP27 site in Egypt to raise awareness about the conservation of coral reefs, particularly vulnerable to climate change. Over 20 species of coral are listed as threatened, and two are listed as endangered under the US Endangered Species Act.
It has been estimated that coral reefs will shrink by at least 70% even if global warming is limited to just 1.5 degrees Celsius, and with a warming of 2 degrees Celsius, almost all coral reefs in the world could be lost by 2070.
The swimmer posted several photos and videos on her Instagram account, documenting her long journey.
Bin Laden was accompanied by endurance swimmer Lewis Pugh, a United Nations Patron of the Oceans.
The forthcoming COP27 climate summit is set to take place in Sharm El Sheikh from November 6 to 18.
Bin Laden, an advocate for Syrian refugees, previously set out to break swimming records to raise awareness of Syrian refugee children and their suffering.
She became the first Arab woman to complete the 4.5 kilometres Hellespont Swim in Turkey, from Europe to Asia, in 2015
