Leonardo DiCaprio wants to save the Great Salt Lake, too

Actor Leonardo DiCaprio directed his 61.1 million Instagram followers this week to sign a petition supporting the Sierra Club's "fight to preserve the Great Salt Lake."

What they're saying: "Sign the petition from @sierraclubutah to ask Utah's political leaders to set an example by protecting and restoring the largest saline ecosystem in the Western Hemisphere," the Oscar-winning actor and climate activist wrote in a Monday post.
