Plastic bags are undeniably convenient and cheap to produce. They are lightweight, sturdy, and easy to carry and store. However, their environmental impact is significant and long-lasting. Made from crude oil and natural gas, plastic bags are non-biodegradable and can take up to 1,000 years to decompose, according to the EPA. They pollute our oceans, harm wildlife, and contribute to the growing problem of plastic waste. Despite the availability of alternatives like paper and cloth bags, consumers and retailers often favour plastic bags due to their low cost and convenience. This has led to a growing movement of cities and countries implementing taxes or outright bans on single-use plastic bags to address the environmental concerns they pose.

What You'll Learn
Plastic bags are cheap to make, but costly to recycle
Plastic bags are cheap to make, costing retailers about a penny per bag. They are sturdy, easy to carry, and store, making them a popular choice for consumers and retailers alike. However, the convenience and low cost of plastic bags come at a significant environmental and economic cost.
The production of plastic bags wastes energy, causes pollution, and poses a serious threat to wildlife and the oceans. Plastic bags are made from non-renewable fossil fuels, and their degradation can take anywhere from 200 to 1000 years. As they break down, plastic bags release toxic substances into the soil, waterways, and the food chain. The clean-up of plastic bags is costly for taxpayers, with California spending an estimated $25 million annually on landfilling discarded plastic bags, and public agencies spending more than $500 million on litter clean-up.
The recycling of plastic bags is also challenging and expensive. While recycled plastic from bags used to be a profitable industry, the falling prices of oil and gas have made it cheaper to produce new bags rather than recycle old ones. The labour-intensive process of recycling is not worth the cost if there is no demand for the final product.
To address the environmental and economic harms caused by plastic bags, many towns and cities have implemented bans or fees on single-use plastic bags. Some countries, such as Bangladesh and Bhutan, have banned plastic bags altogether. Other places, like Ireland and Washington, D.C., have introduced taxes on plastic bags, leading to a significant reduction in their use.
The movement towards reusable bags is also gaining traction, with advocates like Vincent Cobb promoting the use of reusable bags and containers as a more environmentally friendly alternative to both plastic and paper bags. While paper bags are biodegradable and recyclable, their production generates more air and water pollution, and they take up more space in landfills.
The true cost of plastic bags extends beyond their initial price tag, and the efforts to reduce their use and promote recycling are crucial steps towards mitigating their negative impact on the environment.

Plastic bags are convenient and sturdy
Plastic bags are undeniably convenient and sturdy. They are also extremely cheap to produce, with a standard plastic grocery bag costing about a penny to make, according to the plastics industry. This low cost makes them very attractive to retailers, who often provide them to customers for free. In fact, they are so inexpensive that people tend to overuse them, using two, three, or four bags when one would suffice.
The affordability, durability, and ease of use of plastic bags have led to their dominance in the market. They are lightweight, easy to carry and store, and they don't tear easily when carrying heavy items. These qualities have helped plastic bags capture at least 80% of the grocery and convenience store market since their introduction a few decades ago.
However, the convenience and sturdiness of plastic bags come at a cost. Their production wastes energy, causes pollution, and poses a serious threat to wildlife and the oceans. Plastic bags are made from non-renewable fossil fuels and can take more than 200 years to degrade, breaking down into toxic substances that leach into the soil and waterways.
The environmental impact of plastic bags has led to growing calls for a ban or a reduction in their use. Many cities and countries have already implemented taxes or bans on single-use plastic bags to address the problem of pollution and waste management. While plastic bags may be convenient and sturdy, the negative consequences of their use are significant and cannot be ignored.
Despite the concerns, some people argue that plastic bags can be appreciated for their durability and convenience. They suggest that instead of banning them, we should focus on reusing, recycling, and respecting plastic bags to reduce their negative impact on the environment.

Plastic bags are harmful to wildlife and the environment
Plastic bags are cheap to produce, costing around one cent per bag. Their low cost has made them ubiquitous, with 90% of grocery bags now being plastic. However, this has come at a significant cost to the environment and wildlife.
Plastic bags are harmful to wildlife, particularly in the marine environment and in rural areas. Marine animals often mistake plastic bags for food, such as jellyfish, and ingest them. Plastic bags cannot be digested or passed by animals, so they stay in the gut, preventing food digestion and leading to a slow and painful death. In addition to marine life, rural wildlife such as birds can also be affected by ingesting plastic bags or getting entangled in them. The impact of plastic bags on wildlife is not limited to ingestion or entanglement. As polyethylene breaks down, toxic substances are released into the soil and waterways, entering the food chain and potentially affecting all organisms that depend on these ecosystems.
Plastic bags also contribute to pollution and waste. They are often not recycled properly and can escape from garbage trucks, landfills, and consumer hands, ending up in natural environments. Plastic bags can take up to 1,000 years to decompose, and during this time, they can clog storm drains, jam recycling equipment, and float out to bays and the ocean. The cleanup of plastic bag litter is costly to taxpayers, with California spending an estimated $25 million annually to landfill discarded plastic bags, and public agencies spending more than $500 million annually on litter cleanup.
The impact of plastic bags on the environment is also significant. The production of plastic bags wastes energy and causes pollution. They are made from non-renewable fossil fuels, and the equivalent of 439 million gallons of oil is used to produce the 100 billion plastic bags used in the US each year. Plastic bags also contribute to the microplastic pollution in soils, sediments, and freshwater, which can have long-term negative effects on ecosystems.
To address the harmful effects of plastic bags on wildlife and the environment, some countries and cities have banned or taxed single-use plastic bags. Reusable bags are promoted as a more environmentally friendly alternative. By reducing the consumption and promoting the reuse and responsible recycling of plastic bags, we can help protect wildlife, reduce waste, and minimize the negative impact on our environment.

Plastic bags are made from crude oil and natural gas
Plastic bags are extremely inexpensive to produce, costing around one cent per bag. This low cost has led to their widespread use, with plastic bags capturing at least 80% of the grocery and convenience store market. However, the true cost of plastic bags is much higher when considering their environmental impact. Plastic bags are made from polyethylene, which is derived from crude oil and natural gas—fossil fuels that are non-renewable resources.
The production of plastic bags contributes to energy waste and pollution, and their disposal poses a serious threat to our oceans and wildlife. Plastic bags can take up to 1,000 years to decompose, and during this time, they can choke, strangle, and starve wildlife. As they break down, plastic bags release toxic substances into the soil and waterways, which then enter the food chain. The clean-up of plastic bag litter is costly, with California spending an estimated $25 million annually to landfill discarded plastic bags and public agencies spending more than $500 million annually on litter clean-up.
The majority of plastic bags are made from crude oil and natural gas, which are fossil fuels composed mainly of carbon and hydrogen. These compounds are extracted and then refined through processes such as distillation to yield useful chemicals like "monomers," which are the basic building blocks of polymers. One crucial compound in plastic production is naphtha, derived from crude oil. However, natural gas can also be used as an alternative.
The intrinsic link between plastic bags and petroleum is significant, with an estimated 8-10% of the total oil supply being used for plastic production. In the United States, this equates to approximately 12 million barrels of oil annually, contributing to the enormous problem of plastic bag pollution. To put it into perspective, the plastic bags used in the US in a year could, if tied together, circle the Earth's equator 773 times.
While plastic bags are cheap to produce, their environmental and economic costs are substantial. The widespread use of plastic bags has led to their presence in almost every corner of the globe, from Spitsbergen 78° North to the Falklands 51° South. To address this issue, some countries like Ireland, Taiwan, and Bangladesh have heavily taxed or banned single-use plastic bags. Additionally, reusable bags are being promoted as a more sustainable alternative, with the goal of reducing the consumption and waste associated with single-use plastic bags.
