6.5 Impacts on traditional food sources

Traditional food sources are vital for Indigenous communities in the North American West, shaping diets and cultural practices. These systems, developed over millennia, rely on diverse plant and animal species harvested sustainably using traditional ecological knowledge.

Climate change threatens these food sources by altering ecosystems, shifting species distributions, and disrupting harvesting patterns. This impacts wildlife populations, plant-based foods, and water resources crucial for Indigenous diets, creating challenges for hunting, fishing, and food security.
