Within a short period of time, the amount of moisture in soils can begin to decrease. How have plants adapted to cold environments? For example, a few weeks without rain could stress a farmers crops during the growing season. Although droughts occur naturally, excessive water use can cause them to occur more often and be more intense. Because crops and other plants need water to grow and land animals need water to live, droughts can be dangerous.Because of the lack of water, famine occurs and sometimes deserts are created. This is called a flash drought. How has hot desert vegetation adapted to the climate? Ecological impacts also are very important but more difficult to track and quantify.
