How can a decrease in caribou herds affect the world population?

A decrease in caribou herds can disrupt ecosystems, as these animals play a crucial role in their habitats by influencing vegetation patterns and serving as prey for predators. This decline can lead to a loss of biodiversity, affecting other species and the overall health of ecosystems. Additionally, indigenous communities that rely on caribou for sustenance and cultural practices may face food insecurity and cultural disconnection, impacting their livelihoods and well-being. The ripple effects can extend to global ecological balance and food systems.
