Its limitations are that it does not provide early warnings for drought and is not as accurate for use in mountainous areas because it does not account for snow (only rain) as precipitation. The water level in Lake Bosumtwi, Ghana, for instance, fell so low that an entire forest grew on the lakes edges. There is still a lot of debate about the connection between drought andglobal warming, the current period ofclimate change. Thus, if the temperature of the ocean or the surface of the land is relatively cool in a certain area, drought may occur in regions that rely on those sources of moisture. In Sudan, 1 million people died, at least 7 million livestock died, and 7.8 million people were affected. A fundamental difference between plants and animals is that plant cells are enclosed by cell walls while animal cells are not. Farmers and their families were forced to migrate to other areas in search of work, and by 1940, 2.5 million people had fled the Great Plains. She believes water problems such as drought, storms, floods, and degraded water quality will be crucial.
