11. EFFECT OF WATER
POLLTION ON MARINE LIFE
11
There are several effects of water pollution which are faced by
marine life are following:
• In 2010, the accident of BP Deepwater horizon, offshore
drilling disaster.
• In 3rd September 2019, tons of hazardous medical waste
like syringes, blood vials washed up on the Karachi
seashore.
• One-third of china is suffering from the acid rain. The
Acid rain can turn river or lake water acidic, kill fishes and
other animals.
• The nuclear waste is the waste which obtain radioactive
elements.
• The toxic chemical from industrial and agricultural waste
generate fatty tissue of animals which leads toward failure
in their reproductive system.
• The microbial from sewage contain infectious diseases that
infect marine life.

12. “WAYS TO AVERT WATER
POLLUTION”
 Skip the use of plastic instead use / produce an alternate of plastic.
 Avoid direct dumping into water.
 Treat industrial chemicals before draining them into water.
 Abstain from disposing medical wastes in water. .
 Maintain financial budgets to manage the water purification systems.
 Plant trees near water sources and avoid deforestation.
