Plastic pollution is a rising issue that poses a severe threat to the livelihood of the environment, human health, and economies worldwide. Over 460 million metric tonnes of plastic are produced every year in a wide variety of applications. The constant use of plastic, especially single-use plastic items, has led to the widespread contamination of natural habitats, posing risks that extend far beyond the visible litter on our streets and beaches. Understanding the risks of plastic pollution and identifying effective strategies to reduce single-use plastic waste is crucial for safeguarding our planet’s future.

Environmental Impacts of Plastic Pollution

Plastic pollution harms the environment because plastic items do not break down. They accumulate in the air, waterways, agricultural soils, rivers, and oceans. An estimated 20 million metric tonnes of plastic debris enter the environment each year, with significant increases expected by 2040 (CIEL, n.d.). This pollution severely impacts both marine and terrestrial ecosystems. Millions of tonnes of plastic waste end up in oceans annually, creating hazardous conditions for marine animals. Birds, whales, fish, and turtles often mistake plastic debris for food, leading to ingestion or entanglement. Ingesting plastic can cause suffocation or block the digestive tract, leading to starvation (IUCN, n.d.). Entanglement in plastic debris causes injuries that reduce animals’ ability to swim or fly, often resulting in death.

Research shows that microplastics (smaller than 5 mm) and nanoplastics (smaller than 1 mm) have entered every ecosystem. These tiny pieces result from the breakdown of larger plastic items like bottles, bags, tire wear, mulches, and 3D printing (Xia et al., 2023). They are often ingested by a wide range of marine species and are found in all water sources and various types of food (CIEL, n.d.). Microplastics cause physical harm similar to larger plastic pieces and carry harmful toxins. These toxins result in chemical exposure that disrupts entire ecosystems. When marine animals consume microplastics, the chemical exposure follows the food chain. This impacts the health of animals in other habitats and spreads microplastics globally.

Human Health

Human health is also at risk due to plastic pollution. Plastics contain many harmful chemicals such as Bisphenol A (BPA) and phthalates, which seep into food and water sources. These chemicals are carcinogenic and are known to cause endocrine disruption, increased risk of certain cancers, and reproductive, neurological, and immune disorders (IUCN, n.d.). Furthermore, microplastics have been found in various stages of the food chain, often starting with ingestion in marine life, which eventually reaches humans. They have been found in human blood placentas, and food and drinks, such as tap water, beer, and salt (IUCN, n.d.). The long-term implications of microplastics are still being studied, but the potential for harm is significant.

Economic Costs of Plastic Pollution

Plastic pollution has significantly impacted economies worldwide. Governments and organizations spend substantial money on cleaning up plastic waste. Plastic waste in marine environments results in a natural capital loss of $3,300 to $33,000 per ton each year (Xia et al., 2023). This pollution causes income loss in various sectors like tourism, fisheries, agriculture, and water safety (IUCN, n.d.). Plastic pollution in popular areas deters tourists, harming local economies reliant on tourism. Additionally, plastic debris impacts marine life, reducing fish populations and compromising seafood safety. This negatively affects the fishing industry (IUCN, n.d.).

Strategies to Reduce Plastic Waste

Addressing the issue of single-use plastic waste requires a multidisciplinary approach involving policy changes, consumer behaviour shifts, improved recycling systems, education, and innovation.

Firstly, implementing bans on single-use plastics such as straws, bags, and cutlery can significantly reduce plastic waste. Change has already begun with the shift from plastic straws to paper straws in regions of Canada. Slowly but surely, we can come up with alternatives to reduce the daily use of single-use plastics (IUCN, n.d.). Governments can also provide incentives for businesses to develop and use biodegradable or reusable alternatives. Secondly, individuals can make considerable impacts by changing their consumer patterns and opting for reusable items such as water bottles, bags, and containers instead of single-use plastics. Choosing products with minimal or no plastic packaging and supporting companies with sustainable practices can help reduce plastic waste.

Furthermore, enhancing recycling programs to increase the rate of plastic recovery and reuse is vital. Mass upcycling of plastic waste into usable products is essential to help reduce the amount of plastic waste produced every year. Additionally, implementing extended producer responsibility programs can help hold manufacturers accountable for the lifecycle of their plastic products, encouraging them to design products that can easily be recycled. Finally, investing in research to develop biodegradable materials that replace conventional plastics is essential. Biodegradation is one example, however, research is still very limited. Supporting the development of new technologies for more efficient recycling or decomposition of plastics can also play a crucial role in mitigating plastic pollution.
