Environmental activist, actor, and conscious investor Leonardo DiCaprio recently celebrated the 20th anniversary of his eco-forward nonprofit, the Leonardo DiCaprio Foundation.

Vegan primatologist Dr. Jane Goodall and animal rights activist and actor Mark Ruffalo joined the Academy Award-winning actor at the celebratory auction and gala, which raised over $7 million for climate change and biodiversity protection projects.

“Thank you to my friends @janegoodallinst and @markruffalo for coming to @leonardodicapriofdn’s 20th anniversary gala,” DiCaprio wrote on Instagram. “It is leaders like the both of you that help push for positive change for the planet.”

According to the nonprofit’s official website, the Leonardo DiCaprio Foundation was founded in 1998 with the mission of helping to conserve the planet’s last remaining wild ecosystems.

The organization regularly takes steps to protect some of the world’s most vulnerable animals and natural habitats. Some of the foundation’s major milestones include donating $1 million to help restore endangered tiger populations and securing protection for threatened shark species, as well as other marine conservation initiatives. The foundation has also launched a grants program to support nonprofits that take on some of the planet’s most pressing issues.
