The richest man in the world, Amazon founder Jeff Bezos, just announced he’ll use 10 Billion (yes, with a ‘B”) of his own money to fight climate change through the newly established Bezos Earth Fund.

By giving out grants to non-profits, scientists, and activists who are involved in climate work, Bezos hopes to accelerate change.

‘I want to work alongside others both to amplify known ways and to explore new ways of fighting the devastating impact of climate change,’ Bezos said.

Bezos said in the post on Monday that he will call his new initiative the Bezos Earth Fund.

‘Climate change is the biggest threat to our planet. I want to work alongside others both to amplify known ways and to explore new ways of fighting the devastating impact of climate change on this planet we all share,’ he wrote.
