Droughts
A drought means people do not have enough water to drink or
to water their crops. As many places get too much water, some
places will not get enough. When temperatures rise,
moisture
evaporates
from the land, leaving less water behind. Areas in
southern Africa and southern India are all receiving less
precipitation
because of climate change. Deserts around the
world are also expanding. People have to prepare for more
periods of drought in the future by using less water now.
