Leonardo DiCaprio made a splash on Thursday with a $2 million grant to ocean conservation philanthropy group Oceans 5. The outspoken environmentalist has previously donated millions to conserve forests and endangered species as well as oceans.

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

The lucky recipient, Oceans 5, is an international funding collaborative that supports initiatives working to protect marine reserves and reduce overfishing. Recent projects include establishing a marine park in the Southern Cook Islands and securing trade restrictions for endangered sharks.

The $2 million grant comes in addition to the $7 million DiCaprio pledged to ocean conservation in June. “We’re plundering the ocean and its vital resources, and just because we can’t see the devastation from dry land, doesn’t mean it’s any less dangerous,” DiCaprio said at a U.S. State Department ocean policy summit in June.

His interest in the ocean coincides with President Obama's commitment to preserving marine environments. Last month, the White House established the world's largest marine reserve in the South Pacific.

DiCaprio is a deeply committed environmentalist whose foundation has protected "Earth’s last wild places" since 1998. The foundation supports diverse initiatives including the preservation of Sumatran forests, Nepali tigers and endangered sharks.

UN Secretary-General Ban Ki-moon named DiCaprio a UN Messenger of Peace with a special focus on climate change in September. He marched in the People's Climate March last month, and urged the UN to take action on climate change.
