The Sierra Club speaks out against its 'racist' founder, environmental icon John Muir

America's oldest conservation organization is reckoning with its history of racism and the troubling views of its founder, environmental icon John Muir.

"The Sierra Club is a 128-year-old organization with a complex history, some of which has caused significant and immeasurable harm," read a statement posted on the organization's website Wednesday morning.

The post went on to examine the club's own role in "perpetuating white supremacy," and spoke out against its revered founder and "Father of National Parks" John Muir, on his racism and ties with figures involved in eugenics.
