Water

pollution

has negative effects on the environment and is certainly a matter of concern for the environmentalists who aim to protect the surroundings.

This

essay will focus on the major causes which lead to

water

pollution

and discuss the impacts on living beings.

Firstly

, Human activities contribute the most and are the leading cause of

water

pollution

. There are a wide variety of actions contributing to

such

a situation. The dumping of industrial waste into the

water

source

is said to be the primary reason. It not only increases the impurities and chemical content of the liquid but

also

affects aquatic life. The PH value of

water

also

changes as per the chemical dominance making it unfit to consume. Animals are mostly affected by

such

practices

as the only

source

they can rely upon is the natural available

source

such

as rivers, lakes and ponds. Consuming

such

harmful liquid may lead to many diseases or even death.

Additionally

, chemicals may modify their genetics and evolution patterns may get disturbed. In my knowledge, The

water

quality around any industrial area is very degraded and is very harmful to the surroundings and in course of time, the site may become unhabitable.

Secondly

, Other activities

such

as daily human

practices

, lack of awareness and a low number of environmental laws namely, leads to

water

pollution

. Daily

practices

such

as throwing non-degradable waste into the

water

sources, polluting

water

banks, Linking sewage to the

water

stream can

also

be considered as a major threat.

For instance

, Humans pollute the

source

in the

first

place.

However

, they depend heavily on

water

for all the activities.

Furthermore

, consuming bad quality

water

affects the health of users.

For example

, many diseases are directly linked to the quality of

water

and
