Plastic wastes: A serious threat to environment

Plastic wastes: A serious threat to environment

Popular News

Plastic wastes propagated from abandoned plastic objects are detrimental to the environment and have been a paramount cause for environmental pollution. Due to excessive plastic waste, environmental pollution is mushrooming making the life cycle of animals cumbersome in terms of surviving in the environment. Plastic waste is having a devastating effect over human lives as well. Keeping our environment safe, sound and wholesome, is mandatory by taking remedial action to suppress plastic pollution otherwise the situation could become terrible.

Normally, we use a colossal number of products made by plastic particles in our daily life; after using the plastic product, we hurl them into the environment. Afterwards, those abandoned products turn into virulent plastic waste that results in creating plastic pollution. As we all know about the dire characteristics of plastic, that it doesn’t decompose. For instance, the polybags we have been using to carry something over the past twenty years, have not decomposed and added to pollute the environment. Plastic bottles won’t rot for 450 years, existing in the environment.

According to a research conducted by a Bangladeshi non-government institution named environmental and social development organisation, “juvenile boys aged 15 to 25 years are severely responsible for plastic pollution as they mostly use single-use plastic products including coffee cups, juice bottles, soft drink bottles, etc. After using, they cast the bottles, cups and polybags into the environment despite having knowledge about plastic pollution.”

Bangladesh produces 87000 tonnes of single use plastic waste annually. Mercy Tembon, World Bank Country Director for Bangladesh and Bhutan, said that 646 tonnes of plastic waste are amassed per day in Dhaka city.

Due to immense plastic pollution, the life cycle of animals dwelling in the sea including sharks, dolphins, octopus, turtle, etc. are severely hampered. Scientists found plastic waste in the stomach of a dead sea turtle while doing it’s postmortem. They assumed that those plastic wastes were responsible for the demise of that turtle. On the other hand, plastic pollution also has a serious negative impact on human beings. Plastics worsen the fertility of soils and the productivity of crop plants. We often see that sewerages are blocked because of plastic waste following which waterlog appears during the rainy season.

Therefore, efficacious steps need to be taken as soon as possible for dwindling plastic pollution. Recycling of plastic waste could be a stagnant solution for diminishing plastic pollution. Recycling is the practice of gathering discarded and waste materials and reprocessing them for future use. The elements in the waste are separated and processed before being prepared for reuse as raw materials in newer products. Usage of single use plastic should be notably stopped. Usage of sonali bag, a biodegradable and environment-friendly ‘polybag’ made of jute, should be increased. Hopefully, plastic pollution will dwindle in the near future.
