According to the World Food Programme five million Afghans have little or no access to food and eight hundred thousand had left their homes in search of something to eat. Climate change and overpopulation are causing erosion and a collapse of the fragile livelihoods for the majority of rural Afghans. The overgrazing and overpopulation are depleting meadows and agricultural lands, making these ever more vulnerable to the changing climate and increasingly extreme weather in the Hindu Kush-Himalayas mountain range.
