The main food source for adults in the Arctic is a diet primarily consisting of marine mammals, such as seals, whales, and walruses. These animals provide vital nutrients and calories essential for survival in the harsh Arctic climate. Additionally, Arctic communities often include fish, birds, and land animals like caribou in their diets. Traditional hunting practices are crucial for food security and cultural identity, as they often incorporate age-old techniques passed down through generations. As climate change affects the ecosystem, both food availability and traditional lifestyles face challenges, making the preservation of these practices increasingly important.
