Despite being very useful it is advised to restrict the use of plastic. Why is it so? Can you suggest some methods to limit its consumption?

Hint:Plastic is not biodegradable material and one can elaborate on the reasons which can cause it to restrict its use such as harmful to the environment. One can also suggest some alternative methods which can be used to limit the use of plastic.

Complete answer:
1) First of all we will learn about why it is advised to restrict the use of plastic. Plastic is a material that is not a biodegradable material which means that it takes so many years to decompose it into its smaller particles.
2) Plastic is widely used in all walks of daily life and the use & throw type of plastic is used widely and in a very big amount. This causes more plastic material to be thrown in our surroundings which will take many years to decompose. This will pile up the plastic in our surroundings and make many problems. Therefore, we should restrict the use of plastic to reduce harm to the environment.
3) Now we will see some methods which can reduce its consumption as below,
i) We can use the cotton cloth bags for the purpose of buying stuff and should be carried always so as to avoid the materials such as plastic bags.
ii) We can use the metal material formed objects and avoid plastic formed materials such as water bottles and storage containers as metal materials are more long-lasting and not harmful.
4) We should prepare our minds to avoid the plastic material at the point of sale as this will further reduce its use in people's lives.

Note:
Plastic is a chemical material that is an organic polymer. They have very high molecular mass and contain many impurities of other materials. Due to the composition of large molecules, the plastics are degraded at a very large time span. Plastic has a carbon atom as its large constituent with oxygen, nitrogen, and sulfur as minor constituents.
