Durability:

Plastics generally have a short useful life compared to metals. This short life cycle results in pile-ups of unwanted garbage in the office, home or waste yards. Although some of the plastics are recycled, most remain uncollected in dump sites and pollute the environment. Additionally, polythene bags are easily carried by wind, something that makes them almost impossible to collect for recycling.

Low Melting Point:

Plastics generally have a low melting point, so they can't be used where heat levels are high. This also means they cannot be used as protective barrier for furnaces. Some plastic products are highly flammable -- polystyrene, acrylics, polyethylene and nylons commonly used in packaging, home and office appliances. This makes them a fire hazard.

Harmful Nature:

Disposable plastics used in packaging foodstuff meant for human consumption contain harmful compounds. Improper disposal of these packaging products leads to these harmful compounds finding their way to water bodies, where they dissolve over a long time due to their non-biodegradable nature. Littered plastics are also harmful to animals because they occasionally eat them and die. Additionally, plastics fabrication involves the use of potentially dangerous chemicals, which are added as stabilizers or colorants. Most of these chemicals have not undergone an ecological risk appraisal, and their impact on human well-being and the environment is presently vague. One example is phthalates, which are used in the manufacture of PVC.

Environmental Degradation:

Plastics are generally non-biodegradable; hence, they may take centuries to decay. This is due to the intermolecular bonds that constitute plastics, whose structure ensures that the plastics neither corrode nor decompose. Plastics disposed of indecently get washed away to water reservoirs. They clog waterways and float on reservoirs, polluting and making them unsightly.

Hope this will help you!
