Okavango Delta in Botswana looks like a bird's footprint in a bird's-eye view. Composed by lakes, lagoons and riverways, it is the world's largest inland delta and a paradise for wildlife. The precipitation decrease may dry up the peat bog in this area, leading to wildfires and releasing greenhouse gases.
