On Thursday, the US actor and an environmental activist Leonardo DiCaprio has donated $2million from his conservation foundation to the organization ocean 5. The donation was done in an effort to stop overfishing and to establish marine reserves.

Ocean 5 is an international funders' collaborative that supports groups working on ocean conservation projects. The organization's recent projects include establishing a marine park in the Southern Cook Islands and securing trade restrictions for endangered sharks.

DiCaprio says that Oceans 5 as an exciting new platform for marine conservation. The fund will go towards creating large protected areas in the Pacific Islands and the Arctic. It will help to improve enforcement of fishing regulations in Europe, the United States and Central America and will protect threatened shark populations.

DiCaprio established his foundation, the Leonardo DiCaprio Foundation in 1998. It aims to protect the environment and preserve the planet's natural resources and wildlife. The Wolf of Wall Street star has previously donated millions to conserve forests, endangered species as well as oceans.

In 2014, the foundation awarded a $3 million to the World Wildlife Fund to help Nepal increase its tiger population and raised $38.8 million through donations and an art auction at Christie's in New York.

On September, the actor was named a Messenger of Peace by UN Secretary-General Ban Ki-moon to help promote global action on climate change. He marched in the People's Climate March last month, and urged the UN to take action on climate change.

DiCaprio said, "The sad truth is that less than two per cent of our oceans are fully protected. We need to change that now. Working together with other philanthropists, we are making smarter, more impactful investments for the future of our planet".
