No one can live without water. To
be healthy, people need enough water and they need the water to be safe. Water
is not safe when germs and worms from get into it. The germs and worms can be
passed through the water or from one person to another, causing many serious
health problems and affecting a whole community. Chemicals from agriculture,
industry, and mining, and trash dumping can also make our water unsafe and
cause illnesses such as skin rashes, cancers, and other serious health
problems. Not having enough water for drinking, cooking, and washing can lead
to sickness. Especially when there is no way to wash hands after using the
toilet, diarrhea diseases spread quickly from person to person. A shortage of
water for personal cleanliness can also lead to infections of the eyes and
skin. Lack of water can cause dehydration (losing too much water in the body)
and death.
Not having enough water may be
due to drought (dry weather for a long time), the high cost of water, or
because water has not been well conserved. Contamination of water can make the
effects of water scarcity worse, and likewise, water scarcity can make
contamination more serious.
