Plastic Pollution: Understanding The Human Impact And Causes

Plastic pollution is a large-scale environmental issue, with plastic debris found everywhere from Mount Everest to the bottom of the sea. The majority of plastic pollution in the ocean is caused by littering, with plastic waste making up 80% of all marine pollution. However, not all plastic waste in the ocean is caused by littering, with about 20% coming from industrial fishing and manufacturing processes. Plastic pollution has adverse impacts on ocean ecosystems, the integrity of food supplies, and people's livelihoods. It can cause the entanglement, ingestion and suffocation of marine species, and can also seep carcinogenic chemicals into the soil.

Plastic waste from littering

Plastic pollution is caused by the harmful accumulation of synthetic plastic products in the environment. The majority of plastic pollution in the ocean is caused by littering. We buy or use disposable plastic items (such as food wrappings, plastic bags, razors, bottles, straws, containers, etc.) and do not dispose of them properly, which causes them to end up in the waterways and eventually in the ocean.

Littering is not the only cause of plastic pollution in the ocean, however. Many plastics and microplastics are the product of improper manufacturing processes, and about 20% of the ocean’s plastic pollution comes from industrial fishing.

Plastic waste makes up 80% of all marine pollution and around 8 to 10 million metric tons of plastic end up in the ocean each year. This waste has adverse impacts on ocean ecosystems, the integrity of food supplies, and people’s livelihoods. Entanglement and ingestion are the most common hazards for marine species, almost all of which will come into contact with plastic waste during their lives. Entanglement in plastic ropes, lines and discarded fishing gear injures and kills all kinds of marine animals, while ingestion at every stage of the food chain can cause fatalities or have major impacts on physiological functions including nutrition, growth, behaviour and reproduction. Once microplastics and nanoplastics are ingested by marine animals, they become part of the food web and can ultimately enter the human food chain.

Plastic pollution is not just an issue in the ocean. Plastics have been found in many environmental niches, from Mount Everest to the bottom of the sea. Whether being mistaken for food by animals, flooding low-lying areas by clogging drainage systems, or simply causing significant aesthetic blight, plastics have attracted increasing attention as a large-scale pollutant.

Plastic waste from manufacturing processes

Plastic pollution is caused by a variety of factors, including littering, improper manufacturing processes, and industrial fishing.

The manufacturing of plastic products can generate significant amounts of plastic waste, which can contribute to pollution if not properly managed. During the production of plastic items, there may be off-cuts, rejects, and excess material that is not used or recycled. If these plastic wastes are not disposed of or recycled properly, they can end up in landfills or escape into the environment, contributing to plastic pollution.

Improper manufacturing processes can also lead to the release of plastic pellets, known as "nurdles," which are the raw material used to create plastic products. These pellets are often transported and stored in large quantities, and if spilled or released into the environment, they can have detrimental effects on ecosystems.

Additionally, the use of plastic in industrial processes, such as packaging and shipping, can generate large amounts of plastic waste. For example, plastic packaging materials, such as shrink wrap and pallet stretch film, are commonly used to protect and secure goods during transportation. However, these materials are often discarded after a single use, leading to a significant amount of plastic waste.

Furthermore, the manufacturing of plastic products often involves the use of toxic chemicals and additives, which can have harmful effects on the environment if not properly contained and treated. These chemicals may leach into the surrounding soil and water, causing pollution and posing risks to human health and ecosystems.

To address plastic waste from manufacturing processes, it is crucial to implement sustainable practices and improve waste management systems. This includes investing in recycling technologies, promoting the use of eco-friendly materials, and enforcing regulations that hold manufacturers accountable for the proper disposal and recycling of plastic waste. By adopting more sustainable practices, manufacturers can reduce their environmental impact and contribute to the preservation of ecosystems and human health.

Plastic waste from industrial fishing

Plastic pollution is the harmful accumulation of synthetic plastic products in the environment. The majority of plastic pollution in the ocean is caused by littering, but not all plastic waste in the ocean is a result of this. About 20% of the ocean's plastic pollution comes from industrial fishing.

In addition to the direct impacts on marine life, plastic waste from industrial fishing can also have indirect effects on ocean ecosystems and people's livelihoods. Floating plastics can transport invasive alien species, which are a leading cause of biodiversity loss and species extinction. Plastic pollution can also seep carcinogenic chemicals into the soil, further damaging marine environments and potentially impacting human health.

The issue of plastic waste from industrial fishing is a global concern, with plastic debris found in various environmental niches, from Mount Everest to the bottom of the sea. The persistence of plastic pollution in these diverse environments underscores the need for urgent action to address the problem.

Plastic waste in the food chain

Plastic pollution is caused by the harmful accumulation of synthetic plastic products in the environment. The majority of plastic pollution in the ocean is caused by littering, with plastic waste making up 80% of all marine pollution. However, not all plastic waste in the ocean is a result of littering; some plastics and microplastics are the product of improper manufacturing processes, and about 20% of the ocean's plastic pollution comes from industrial fishing.

Plastic waste has a significant impact on the food chain. Wildlife such as birds, whales, fish, and turtles mistake indigestible plastic waste for food, which can cause fatalities or have major impacts on physiological functions including nutrition, growth, behaviour, and reproduction. Once microplastics and nanoplastics are ingested by marine animals, they become part of the food web and can ultimately enter the human food chain.

Entanglement in plastic ropes, lines, and discarded fishing gear is another hazard that injures and kills marine animals. Plastic pollution can also cause internal and external injuries that reduce the ability of animals to swim and fly. Domesticated farm animals are also affected by plastic pollution.

Floating plastics can transport invasive alien species, which is one of the leading causes of biodiversity loss and species extinction. Plastic pollution can also seep carcinogenic chemicals into the soil.

Plastic waste and wildlife entanglement

Plastic pollution is caused by the harmful accumulation of synthetic plastic products in the environment. The majority of plastic pollution in the ocean is caused by littering, but not all plastic waste in the ocean is a result of littering. Some plastics and microplastics are the product of improper manufacturing processes, and about 20% of the ocean's plastic pollution comes from industrial fishing.

Plastic waste makes up 80% of all marine pollution, and around 8 to 10 million metric tons of plastic end up in the ocean each year. This waste causes the ingestion, suffocation, and entanglement of species. Entanglement in plastic ropes, lines, and discarded fishing gear injures and kills all kinds of marine animals, from microscopic zooplankton to the largest marine mammals.

Entanglement in plastic waste can cause external injuries that reduce the ability of animals to swim and fly. It can also cause internal injuries, which can be fatal. Wildlife such as birds, whales, fish, and turtles mistake indigestible plastic waste for food and die of starvation as their stomachs become filled with it.

Plastic pollution also affects domesticated farm animals. Floating plastics can transport invasive alien species, which are one of the leading causes of biodiversity loss and species extinction.
