Potential impacts of climate-related decline of seafood harvest on nutritional status of coastal First Nations in British Columbia, Canada.
BACKGROUND:Traditional food systems are under pressure from various stressors, including climate change which is projected to negatively alter the abundance of marine species harvested by coastal First Nations (FNs) in British Columbia (BC). OBJECTIVE:To model the potential impacts of the climate-re...
