Question

Article on pollution causes and solutions for 9 class in 120 to 150 words

Answer 1

Hey! :) You can include the following points in your article:

Causes
-natural causes like volcanic erruptions and forest fires, though they contribute very little
-over exploitation of natural resources
-burning of fossil fuels
-leaded petrol used as fuel in vehicles
-smoke from power plants
These can be written in case of air pollution.

For water pollution:
-dumping of wastes into water bodies
-bathing of animals
-draining of industrial effluents

For noise pollution:
-un-necessary honking of vehicles
-loud music
-fire crackers(this can be mentioned as a cause of air pollution as well)
-construction sites-machinery create a lot of noise

Solutions:
-using lead free petrol
-natural gas as fuel
-installing precipitators and scrubbers in chimneys of power plants so that smoke released is cleaner and less harmful
-banning of industrial drainage into clear water bodies
-limiting loud noise by putting a decibel limit
-reducing use of fire crackers
-awareness campaigns, silent marches, plays, etc.

These are the main key points you can include and provide subtle ones of your own. Hope these help. Mark this as brainliest if you think it's worth it. All the best! :D
