White people have always decided what is “natural,” as well as who “naturally” belongs and who doesn’t. John Muir did not do “some powerful work for conservation and parks.” He co-founded the Sierra Club and worked to ensure that Ahwahnee became Yosemite National Park — these structures are tools that maintain power for a few (white people, particularly white men), as well as perpetuate gatekeeping (the practice of limiting and controlling resources). National Parks are active tools in ongoing indigenous genocide.
