Ready for a healthy dose of déjà vu? The Leonardo DiCaprio Foundation just doled out millions to support environmental groups and conservation initiatives around the world.

Sounds familiar, right? In the last two years alone, DiCaprio has donated millions to protect ocean habitats, support tiger populations, protect elephants, and even help fund Adrian Grenier's "Lonely Whale" nature documentary. Much of this generosity has come thanks to his impressive fundraising efforts which, through a variety of celebrity-rich galas and art auctions, have managed to bring in more than $60 million since 2013. This latest $15 million dollar gift, the biggest yet, is but another piece of his promise to take those donations and quickly use them to make an impact.

"We have a responsibility to innovate a future where the habitability of our planet does not come at the expense of those who inhabit it," DiCaprio said in a statement.

While grants given out in the past have focused on one or two organizations, this latest round will benefit more than 27 organizations, including Dark Snow, the Virunga Fund, Bioneers and Empowered by Light.

“The destruction of our planet continues at a pace we can no longer afford to ignore,” DiCaprio added. “I am proud to support these organizations who are working to solve humankind’s greatest challenge.”

The 40-year-old actor, whose upcoming movie "The Revenant" placed him in the wilds outside Alberta, Canada, also recently announced a donation of a different kind: an art installation piece called "Solar Reserve" by artist John Gerrard. The massive work, containing a 28 × 24 foot frameless LED wall, presents a digital simulation of a Nevada solar thermal plant and its surrounding landscape.

The piece is expected to appear at the Los Angeles County Museum of Art (LACMA) later this year.
