Why is the Government imposing ban on the use of polythene bags and plastics? Suggest alternatives. How is this ban likely to improve the environment?

Explanation

(i) Polythene bags and plastics are non-biodegradable materials.
(ii) If they are used, they accumulate in the soil,water bodies etc.,
(iii) In the soil, they get buried and alter the nature of the soil. It prevents aeration of the soil and affects microbes. Excessive accumulation of plastic can render the soil barren.
(iv) In water bodies, they cover the water surface and prevent oxygen from diffusing into the water thereby affecting aquatic flora and fauna.
(v) Plastic covers also find their way into the stomach of animals during feeding and may even prove to be fatal.
(vi) Burning of plastics, produces dioxin which can cause developmental and reproductive problems, damage the immune system.
Alternate methods to avoid plastics are:
(i) Use bags made of ecofriendly materials.
(ii) Use dining plates / cups made of biodegradable materials instead of plastic plates / cups.
(iii) Use vessels / containers made of steel.
(iv) Carry our own cloth bags for shopping.
The ban on plastics by the Government will improve the environment because :
(1) Plastic waste will be reduced and slowly disappear.
(ii) It will help the water bodies and soil to promote microbial growth.
(iii) It will lead to decrease in challenges faced by Government in disposal of solid waste.
(iv) Human beings will not be exposed to health hazards caused by use of plastics especially dining plates and cups.
