November is Indigenous Heritage Month, and the Sierra Club is celebrating the many Native American changemakers in the environmental world. From the struggle over the Line 3 pipeline in Minnesota, to the fight against fracked gas exports on Texas’s Gulf Coast, Indigenous leaders are on the frontlines of many of today’s most urgent environmental struggles.

We recognize the vast diversity of Indigenous people in the US. Many of them have sought reciprocal and sustainable relationships with the earth since time immemorial. Because of the centuries-long and ongoing theft of Indigenous territories, Indigenous Peoples today hold just 5 percent of the world’s lands. Nevertheless, they safeguard 80 percent of its biodiversity. Honoring Indigenous sovereignty and ancestral wisdom is a key part of confronting the environmental challenges we face.

Join us in learning about, and celebrating, Indigenous environmental changemakers this month—and all year round. We also encourage you to take this opportunity to research what Native land you’re currently occupying, and how you can support Indigenous-led environmental struggles in your community.
