The Sierra Club was founded by John Muir in 1892.
The Sierra Club is one of the oldest grassroots environmental groups in the nation. They fight every day to encourage people to “go green.” This doesn’t just mean asking you to recycle.
Although they definitely support small-scale efforts like turning off the lights when you leave a room, they also go big. They have written legislation to change laws. They have worked hand-in-hand with presidents over the decades. They have even created entire preserves and national parks.
They remain as strong and active today as they were when they were formed. They currently follow all environmental issues and protest actions with which they disagree.
