The disposal of plastic wastes is a major problem because of the following reasons:
i) Plastic is non-biodegradable. It takes several years for plastic to decompose and it is not environment-friendly.
ii) It causes environmental pollution.
iii) The disposal of plastic wastes is a major problem. Plastics cannot be burnt because they release poisonous gases.
iv) Plastic bags thrown in the garbage can be swallowed by the animals such as cows. It can result in choking their respiratory system and can be fatal.
Therefore, we must avoid the use of plastic as much as possible.
