Los Angeles: Foundations funded and co-founded by Leonardo DiCaprio and Jeff Bezos have launched an initiative committing $200 million to revive 100 of Earth's most threatened species, including endangered lemurs, salamanders, pangolins, pigs and echidnas. DiCaprio's Re:wild and the Bezos Earth Fund are leading the Phoenix Species Project, the groups announced Tuesday. They call it the largest single fund in history dedicated exclusively to recovering critically endangered species.DiCaprio has for years been developing the idea of a major concerted effort to help species whose habitats and future existence are threatened by climate change. In 2021, he and Re:wild co-founder Wes Sechrest, a biologist who serves as the organization's CEO, met with the Amazon-founding mega billionaire Bezos and his wife, former TV news reporter and host Lauren Sanchez Bezos.
