Happy Earth Day! Interior protects amazing natural landscapes at public lands across the country, sustains healthy habitat for fish and wildlife, and develops cutting-edge science to better understand the forces that shape the planet. From a family of kayakers at Everglades National Park in Florida to this majestic ground squirrel at Denali National Park in Alaska, we wish everyone and everything on our only home, a positive Earth Day.
