Water pollution is the contamination of bodies of water such as lakes, rivers, oceans, and
groundwater ( the water beneath the Earth's surface). It is one of the most serious types of
pollution.
Water pollution can have many different causes. Factories dump industrial waste into lakes
and rivers. Farms using pesticides to kill insects and herbicides to kill weeds can also lead to
water pollution. These factors cause 'point source' pollutants from storm water and the
atmosphere result in 'non-point source' pollution.
Water pollution can have dramatic effects. In many poor nations, there are frequent
outbreaks of cholera and other diseases because of people drinking unstreated water. Human
can even die if they drink contaminated water. Polluted water also causes the death of aquatic
animals such as crabs, fish or birds. Other animals eat these dead animals and may also get
sick. In addition, herbicides in water can kill aquatic plants and cause further damage to the
environment. So what should we do to reduce water pollution?
