Actor Leonardo DiCaprio has pledged $43 million (£30.4m) to the help conserve the Galápagos Islands in Ecuador. The money will go to Re:Wild, an organisation founded earlier this year by DiCaprio and a team of conservation specialists, the Galápagos National Park Directorate, Island Conservation, and local communities. The money will go towards restoring Floreana Island, which is home to 54 threatened species, as well as reintroduce 13 extinct species. It will also introduce a captive breeding programme to prevent the extinction of animals such as the pink iguana.
It's not the first time DiCaprio has put his money towards conservation and saving endangered species through his eponymous foundation. The Leonardo DiCaprio Foundation has awarded more than $80 million (£57.5m) in grants since 2010, funding more than 200 high-impact projects across 50 countries.
