polluted water.

g When infected aquatic animals are
eaten by human beings or other
animals, it makes them sick and unhealthy.

We must check water pollution if we want to improve the quality of water

bodies. Water pollution should be controlled because there is limited
amount of fresh water on our earth.

Discuss about the factors causing pollution of these water bodies.

Every Drop Counts

Water is precious. Although 70% of our earth is covered with water, still
all this water cannot be used for daily activities as most of it is salty. Fresh
water is available in the form of underground water, water in rivers, ponds
and lakes. This is not sufficient for everyone. This is the cause of water

shortage.
