Drought can change the actual landscape of the Earth. A prolonged period of dry weather, not even necessarily hot, produces changes in the earth such as: * increased desertification (formation of desert lands) * reduction and degradation of animal and plant habitats * reduction of animal and plant species, having an overall effect on the food chain and predation among the species * wind erosion of soils and loss of topsoils * dust storms and sandstorms, which take tonnes of dust and sand and dump them elsewhere * increased bushfires and wildfires, both in number and severity
