Answers
Due to its light weight, high strength, good flexibility, performance, low economic cost plastics have gained wide-spread acceptance.
Polythene bags are the agents of air pollution, cancer, and skin diseases. It is used like a slow poison in daily life. In the process of recycling poly bags, the producers use a large number of hazardous chemicals which are injurious to our health.
Calcutta Medical College Hospital says that taking tea in poly cup can be the cause of ulcer. Experts say, polythene bags and other plastic materials, if burnt below 7000 degree Celsius, create poisonous gas which can cause cancer and skin diseases. The polythene wrapped fish, vegetables and meat are infected by anaerobic bacteria which is responsible for skin disease and cancer.
Plastic bags choke drainage system and water supply channels. The blocked drainages lead to dangerous diseases like filariasis, dengue and malaria. Plastics pollute rivers, canals and lakes as also other water-resources.
The environmentalists feel that poly bags are a serious threat to the environment and also release toxic gases in to the atmosphere. It is a simple issue which can be solved easily, but if neglected can lead to serious consequences. So, we must follow precautions and initiate measures to save our environment as well as our life.
Plastic is widely used in our day to day life. Starting from a pen to a polythene bag in which we carry fruits and books are forms of plastic. Though convenient in our day to day use, it has posed an alarming threat to the environment.
Plastic is non-biodegradable and do not decay by biological actions of microbes. They remain in the same state as we throw them. So, dumps or garbages are created making our cities and soil polluted.
Harmful Chemical:
To destroy plastics, we can either recycle or burn them. If we burn plastic, they emit harmful chemical gases like carbon dioxide (CO,), carbon monoxide (CO), nitrous oxide (NO), methane (CH4), sulphur dioxides (SO2), etc. These gases pollute our environment, though in negligible content, they add to green house effect and endanger our environment.
Damage Sanitary System:
The wastes of plastic block pipes and sanitary lines so that dirty water came out on roads. This cause fear of malaria, cholera and other diseases.
The wastes of plastic bags, bottles, etc. are drawn to a sea or an ocean by rivers and they are deposited in them. They pollute and disturb the eco-system of the sea or the ocean.
Ecosystem Imbalance:
Due to wide scale use of plastic, water, soil and air pollutions are caused. These polluted components of environment lead to imbalance of various ecosystem of the Earth.
Only solution to this plastic hazard is to take preventive measures and for that,
a. To reduce use of plastic wherever possible
b. To use recyclable bags and things
c. To recycle the used plastic
d. Not to throw used plastic here and there
e. To collect the used plastic by the Government and then to recycle.
f. Only recyclable plastics should be allowed to use
g. Some legal norms should be declared.
