View Answer
Ans:
We use many plastic items such as tooth brush, combs, containers, bottles, shoes, toys, wires, frames and bags every day but using plastic is very harmful in terms of health and as well as the environment. Plastics are not suitable for storing cooked food because they emit harmful chemicals when they are exposed to high temperatures. Using plastics causeshealth problems such as heart disease, lungs infection and diabetes. Plastics should be disposed in the right way because harmful gases are emitted from burning plastics, which cause cancer and they kill living beings. That is why Plastics thrown casually get into drains and sewages, often blocking the way and causingwater-logging. So polythene bags should not be used for garbage disposal.
Measures taken to prevent from the dangerous effects of plastics:
Reduce, reuse and recycle plastics.
Carry jute or cloth bags for shopping
Do not store food items in plastic bags.
Do not burn plastic items.
Recycle plastics so that new plastic items can be made.
Waste that does not decompose should be put in blue dustbins, while waste that decomposes easily should be put in green dustbins.
