First a short bit on what polyethylene is:
Polyethylene is a long chained organic molecule that is formed from ethylene (H2C=CH2).It contains no other materials than Carbon and Hydrogen. The basic building block (ethylene) is a non toxic gas that can act as a hormone in plant growth, speeding ripening and the rowth of seedlings.
The harmful effects of polyethylene are more related to the forms that it is made into - films, ropes, six-pack holders, milk jugs etc. As trash it is refractory in the environment, lasting for many years without decomposition except if it is exposed to sunlight. As trash, due to its shapes it has been observed to trap animals legs and heads.
If collected it can be easiiy recycled reducing the need for consumption of fresh raw materials and energy. If burned, it is converted to carbon dioxide and water.

the waste is very harmful. it can cause the death and diseases. If the waste is recycled it may not be harmful. but there is a non degradable waste which is most harmful namely plastic or polythene. if it is left in free air it pollutes the air. if in soil it pollutes soil. thus if it is left free anywhere it spoils the thing. so the polythene and plastic has a harmful effect on the environment. so the " degradable plastic "should be used. or a new degradable alternative of plastic should be invented. there are two types of wastes : solid , liquid . the waste not only harms on human health but it also effects on the health of all the organisms. Thus it is very harmful.

Polythene is not biodegradable * Polythene threatens the life in the water bodies. The polythene articles (e.g. six pack rings) affects the survival of animals the aquatic and marine ecosystems. * Polythene is also likely to clog the drains causing problems in the water flow of the pipes. The pipe blockages would cause flooding and the free flow of water is disturbed. * Polethene is harmful for animals if swallowed. It can accumulate in the bowels which ultimately becomes lethal to the animal. * In most households poly bags are used to preserve food items. Reused bag may be contaminated by materials harmful to human health.
