Diné citizens against ruining our environment refers to the grassroots movement among the Navajo Nation, advocating for environmental justice and the protection of their land and resources from harmful industrial practices. This movement is rooted in the Diné philosophy of living in harmony with the earth and seeks to address the negative impacts of mining, pollution, and climate change on their ancestral lands. The group emphasizes the importance of preserving natural resources for future generations, aligning their activism with broader environmental concerns that emerged in the conservation movement.
