Plastic is non-biodegradable and harmful to the environment
Plastic is a synthetic polymer that has become an integral part of our lives, with numerous daily-use products made of plastic. However, plastic is non-biodegradable, which means it cannot be decomposed by microbes, and therefore, it becomes trash that harms the environment.
Plastic waste, such as plastic bags, often becomes litter, with plastic constituting around 7% of the average household dustbin. In 2003, nearly 57% of the litter found on beaches was plastic. Plastic bags thrown away carelessly on roads and other places find their way into drains and sewage pipes, clogging them and causing dirty water to spill onto the roads. Plastic bags are also consumed by stray cattle, causing their deaths.
The accumulation of plastic waste leads to significant environmental issues, contributing to pollution in land and water bodies and harming wildlife and ecosystems. Plastic does not decompose since it is non-biodegradable and takes hundreds of years to degrade. Even the manufacturing of plastics creates a large number of chemical pollutants. Plasticizers like phthalates are suspected to cause upheaval in the hormone systems of animals and people, especially children.
Additionally, burning plastic produces harmful gases and fumes, which can be extremely harmful to human health. Plastic is also difficult to recycle due to the great variety of plastics, which are hardly distinguishable. Some plastics, like PVC, contain chlorine, which returns to the environment when the waste is processed.
Therefore, while plastic has been a boon to humankind with its versatility and usefulness in various applications, its non-biodegradable nature and the resulting harm to the environment make it a curse.

Plastic waste clogs drains and sewers, causing flooding
Plastic is a synthetic polymer with numerous applications in our daily lives. Its versatility, durability, and low cost have made it indispensable. However, the excessive use of plastic and improper waste disposal have created significant environmental challenges, including clogged drains and sewers that lead to flooding.
Plastic waste, particularly plastic bags, is a significant contributor to drain and sewer blockages, which can result in flooding, especially during heavy rainfall. Plastic bags, bottles, and other plastic items carelessly discarded on roads and in open spaces find their way into drains and sewers. This plastic waste accumulates and blocks these water channels, causing dirty water to back up and spill onto roads and other areas.
The impact of plastic waste in drainage systems is more severe in densely populated urban areas, where rapid urbanisation, industrialisation, and population growth have already strained drainage infrastructure. Poor maintenance of drains and sewers further exacerbates the problem. During heavy rains, the clogged drainage systems cannot effectively manage the water flow, leading to flooding in cities and urban regions.
The consequences of plastic waste-induced flooding are far-reaching, particularly in low- and middle-income communities. These areas often lack adequate urban drainage, solid waste management, and sanitation systems, making them more vulnerable to the impacts of flooding. The stagnant water caused by flooding also poses health risks, including the spread of gastrointestinal diseases such as cholera and diarrhoeal illnesses.
To mitigate the issue of plastic waste clogging drains and sewers, it is essential to promote responsible plastic use and proper waste disposal. This includes reducing plastic consumption, reusing and recycling plastic items, and ensuring that plastic waste is not discarded in open spaces or drains. Additionally, implementing effective garbage collection systems and regular cleaning of drainage systems can help prevent blockages and reduce the risk of flooding.

Plastic is harmful to humans and animals
Plastic is a synthetic polymer that has become integral to our daily lives. However, it is also a significant source of pollution, endangering both human and animal health.
Plastic pollution has infiltrated every ecosystem, from the Antarctic tundra to coral reefs, and is a leading cause of biodiversity loss and ecosystem degradation. Animals often mistake plastic waste for food, leading to starvation as their stomachs become filled with indigestible material. It also causes internal and external injuries, reducing their ability to move. Over 1,500 species in marine and terrestrial environments are known to ingest plastic, with birds, whales, fish, and turtles being some of the most affected. Plastic pollution also poses a threat to domesticated farm animals and has been detected in the meat, milk, and blood of these animals.
The impact of plastic pollution on human health is equally concerning. Microplastics, which range in size from 5mm to 1 nanometer, have been found in human blood, placentas, and even in food and drinks. The main route of microplastics exposure for humans is ingestion, followed by inhalation and dermal exposure. While the exact amount of plastic ingested by humans is unknown, estimations suggest it could be around 0.1-5g per week. Inhalation of airborne microplastics can be even higher, with up to 22,000,000 micro- and nanoplastics inhaled annually. Recent studies have found a correlation between the presence of microplastics in the human body and inflammatory bowel disease symptoms and respiratory complications. Additionally, plastics can act as a vessel for human pathogens, increasing the risk of disease transmission.
The production and disposal of plastic also have negative consequences. More than 16,000 chemicals are used to make plastic, with at least 4,200 of these being chemicals of concern. Many of these chemicals are known to be carcinogenic and can leach into tap water, potentially causing developmental, reproductive, neurological, and immune disorders. Improper disposal of plastic waste further exacerbates the problem, as plastic does not decompose and can remain in the environment for hundreds to thousands of years.
While plastic has undoubtedly brought convenience and innovation, its harmful effects on humans and animals cannot be ignored. Addressing plastic pollution and reducing plastic usage are crucial steps towards mitigating these impacts and preserving the health of our planet and its inhabitants.

Plastic is difficult to recycle
Plastic is a synthetic polymer that has become integral to our daily lives. However, it has also become a significant environmental concern due to its non-biodegradable nature and the challenges associated with recycling it.
Recycling plastic is difficult because it is composed of various polymer types, each with distinct melting points, making it nearly impossible to recycle different plastics together. The process of separating plastics for recycling is time-consuming and costly, and certain types, like black plastic food trays, further complicate the process due to their colour.
Additionally, the quality of most plastics deteriorates upon recycling, a process known as downcycling. This results in recycled plastics requiring the addition of virgin plastics or other materials to maintain their value. Furthermore, the plastics industry relies heavily on non-renewable resources, with over 90% of global plastic production being primary plastics derived from petroleum products. This dependence contributes to significant energy consumption and greenhouse gas emissions.
While mechanical recycling shortens polymer chains and degrades quality, advanced recycling approaches, such as chemical recycling, offer a potential solution. Chemical recycling breaks down plastic molecules into individual subunits, allowing for reassembly into polymers. This technique could enable the recycling of thermosets, a type of polymer that cannot be melted down and mechanically recycled.
Despite these advancements, the demand for virgin plastics remains high, driven by their relatively low production cost. This creates a competitive environment that makes recycled plastics significantly more expensive. The fragmented nature of the market further exacerbates the challenge, making it difficult for sellers of recycled plastic to find buyers.
In conclusion, while plastic has numerous benefits and applications, its recycling challenges contribute to a growing environmental crisis. Addressing these issues requires a multifaceted approach, including scaling recycling technologies, developing solutions for hard-to-recycle plastics, and reducing the production and use of single-use plastics.
