Nature is our life support system and it’s fragile,” Bezos said Monday at an event in New York City. “I was reminded of this just this July when I went into space with Blue Origin. I’d heard that seeing the Earth from space changes one’s point of view of the world, but I was not prepared for just how much that would be true.”

Earlier this month, the fund said it would give away $203.7 million by the end of the year to organizations advancing climate justice, among other causes. That’s after it awarded $791 million in grants last year to 16 organizations, including the World Wildlife Fund, the Natural Resources Defense Council and the Nature Conservancy.
