One
major problem that environmental scientists are bothered about is the contamination of
water
bodies
such
as rivers, lakes, and seas.
This
essay will
first
discuss the inappropriate disposal of domestic and industrial
waste
into the aquatic environment as a fundamental cause of
this
water
pollution
, and
then
analyze the inimical
effect
this
practice can have on human and aquatic
lives
.
A number of factors have been considered as responsible for
water
pollution
.
One
of
such
factors is the indiscriminate practice of dumping
waste
on
water
beds. by individuals and large industries.
This
is because; in many developing nations, there is yet no proper organized
waste
management scheme to coordinate effectively the disposal of
waste
.
Besides
, there is no firm legal provision that guides against improper
waste
disposal by large manufacturing companies.
Consequently
, most individuals and factories find it convenient to dispose of their
waste
into the riverbeds or sea.
For instance
, liquid
waste
from large factories is increasingly being dumped into the sea on daily basis. Another cause of
pollution
of the aquatic habitats is the
effect
of
oil
spillage from petrochemical industries, especially in the riverine areas. In the process of transporting
oil
through the sea borders across major cities,
oil
tends to spill on the
water
bodies
with devastating consequences on aquatic
lives
.
Considering the
effect
of
this
pollution
on the
lives
of humans and aquatic organisms,
one
major problem is the direct harmful effects
this
chemical
waste
has on the fishes and other aquatic life. Some of them died immediately from the toxic
effect
of these
waste
products, while others tend to accumulate these wastes in their systems, and pass it down the food chain to man, who happen to be
one
of the final consumers at the end of the food chain. The chronic complications of the build-up of
such
toxic chemicals in the human system are worrisome.
Furthermore
, the
effect
of
oil
spillage on riverine communities, destroying the lands for the local farmers; and even taking away their jobs is
also
a concern.
To conclude,
one
important cause of
water
pollution
is improper domestic and industrial
waste
disposal in
water
bodies
; and the dire consequence on aquatic and human
lives
cannot be under-estimated. It is believed that in the future, with public enlightenment on the bad consequences of dumping
waste
on
water
bodies
,
