What You'll Learn
Plastic is not biodegradable
Plastic is a synthetic or semi-synthetic material made of polymers that can be shaped or moulded easily. It is deeply intertwined with our modern lives, existing in nearly every industry, from food to cars to footwear to space equipment. However, plastic is notorious for being bad for the environment and contributing to plastic waste, pollution, debris, packaging waste, and waste generation.
While biodegradable plastics are becoming a more frequent option on store shelves, it is important to understand that they are still plastics. Biodegradable plastics are intended for short-lived use and often stay in the environment for a long time before they degrade. They are tested to ensure they break down under controlled conditions in a lab, but nature does not have controlled conditions. Therefore, it cannot be certain that biodegradable plastic will actually biodegrade in the natural world if it is littered.
When biodegradable materials do not break down, they have similar consequences as their non-biodegradable counterparts, polluting the ecosystems and habitats that both nature and people depend on. This pollution can alter habitats and natural processes, reducing ecosystems' ability to adapt to climate change and directly affecting millions of people's livelihoods, food production capabilities, and social well-being. Plastic also threatens ecosystems, lowers biodiversity, and can change the flow of nutrients between plants and animals. As plastic is worn down by seawater and sand, it creates microplastics, which have been found in the guts of plankton and sediment layers of the ocean floor.
The production of plastic also has negative impacts on the environment. Extracting the fossil fuels required to create new plastics disturbs wildlife, pollutes groundwater systems, and causes oil spills in the ocean. The production process releases greenhouse gases into the atmosphere, contributing to human-induced climate change. Additionally, the distribution of plastic products requires burning more fossil fuels for international delivery, further exacerbating the problem.
To address the plastic pollution crisis, it is crucial to reduce and reuse plastic and shift to a circular economy. While compostable and biodegradable plastic can play a helpful role in reducing waste, they should only be used when they add value, make sense for the product use, and work with the systems that can recover them. Policymakers must promote long-lasting products and eliminate lightweight and short-lived plastic products. Ultimately, the best way to fight the plastic crisis is to cut its production.

Plastic waste is often shipped to developing countries
Plastic is not eco-friendly due to its negative impact on the environment and human health. Since plastic first became mainstream in the 1950s, over 8.3 billion metric tons have been produced, and due to its engineered durability, most of it still exists today. Only a tiny fraction of all plastics ever produced has been recycled, with a 2022 study from the U.S. Department of Energy estimating that only 5% of plastic waste is recycled, while 86% is sent to landfills and 9% is incinerated. The production and disposal of plastic contribute to environmental pollution, with plastic waste ending up in oceans, waterways, and dumps, posing risks to ecosystems, human health, and public health.
One reason for this is the hidden plastics included in other product categories, such as textiles, contaminated paper bales, and electronics. These products are not always counted as plastic waste in trade data, leading to an underestimation of the true scale of the global plastic waste trade. For example, discarded clothing may not be tracked as plastic waste even though a significant percentage of textiles contain plastic. This hidden plastic waste strains the waste management systems of developing countries, as they must first separate and remove the plastic before recycling the remaining materials.
Another factor contributing to the issue is the contamination of plastic waste. Many developing countries lack the resources and infrastructure to properly recycle mixed or contaminated plastic waste. As a result, materials that cannot be recycled may end up being burned illegally, dumped in landfills, or released into waterways, further exacerbating the environmental and health risks associated with plastic pollution.
Furthermore, the surge of plastic waste has overwhelmed the waste management systems of importing countries, leading to new controls and bans on plastic waste imports in some nations. Countries such as Malaysia, Thailand, Vietnam, and India have taken steps to reduce or prohibit plastic waste imports due to concerns about contamination and pollution. This has led to a shift in the global plastic waste trade, with plastic waste being diverted to other countries that may not have the capacity to manage it effectively.

Plastic production requires fossil fuels
Plastic is a material that is deeply intertwined with modern life. It is used in nearly every industry, from food to cars to footwear to space equipment. However, plastic is also notorious for being harmful to the environment and human health due to the manufacturing process, which requires fossil fuels.
The production of plastic involves extracting fossil fuels, which disturbs wildlife, pollutes groundwater systems, and causes oil spills in the ocean. It also releases greenhouse gases into the atmosphere, contributing to climate change. The distribution of plastic products, which are often intended for international markets, further exacerbates the problem as it requires burning more fossil fuels.
In addition to the environmental impact of production and distribution, the very characteristics of plastic that make it so useful also contribute to its negative impact on the environment. Plastic is engineered not to break down, which means that the majority of the plastic ever produced is still around today. As plastic is worn down by seawater and sand, it creates microplastics—plastic bits smaller than 5 millimeters—which are even more pervasive than larger plastics. These microplastics have been found in the guts of plankton, one of the ocean's smallest living creatures, and in the sediment layers of the ocean floor.
While biodegradable and compostable plastics are becoming more popular as consumers seek more sustainable options, they are not a complete solution to the plastic pollution crisis. Biodegradable plastics are still plastics, and they often stay in the environment for a long time before they degrade. They are intended for short-lived use, but if they end up as litter, they can have the same consequences as their non-biodegradable counterparts, polluting ecosystems and habitats.
To truly address the plastic pollution crisis, a systemic transformation is needed to transition to a circular economy. Policymakers must promote long-lasting products and work towards eliminating lightweight and short-lived plastic products. Reducing, reusing, and recycling plastic are important, but the most effective solution is to cut plastic production and promote the use of alternative materials when possible.

Plastic threatens ecosystems and lowers biodiversity
Plastic is a material that is deeply intertwined with modern life. It is used in nearly every industry, from food to cars to footwear. However, plastic poses a significant threat to ecosystems and biodiversity.
Plastic pollution can alter habitats and natural processes, reducing ecosystems' ability to adapt to climate change. It directly affects millions of people's livelihoods, food production capabilities, and social well-being. The production and distribution of plastic contribute to environmental degradation and negatively impact nearby marine environments. The extraction of fossil fuels, for instance, can disturb wildlife, pollute groundwater systems, and cause oil spills. As plastic breaks down into microplastics, these tiny particles can be ingested by marine organisms, leading to health issues and even death.
Microplastics, defined as plastic bits smaller than 5 millimeters, are highly pervasive. They have been found in the guts of plankton and sediment layers on the ocean floor. The accumulation of microplastics in the environment corresponds with the historical trend of plastic production worldwide. Even larger plastics, such as water bottles and plastic bags, can sink to the ocean floor when algae and other life forms grow on them, adding weight.
Biodegradable plastics have emerged as a potential solution to the plastic pollution crisis. However, they are not without shortcomings. Biodegradable plastics often stay in the environment for extended periods before degrading, and their ability to biodegrade in natural conditions is uncertain. While they can play a helpful role in specific applications, such as compostable take-out containers, they should not be solely relied upon to address plastic pollution. To effectively tackle the plastic crisis, a systemic transformation is necessary, focusing on reducing, reusing, and recycling plastic to transition to a circular economy.
In conclusion, plastic poses a significant threat to ecosystems and biodiversity. Its presence in the environment can disrupt natural processes, harm wildlife, and negatively impact human livelihoods. To mitigate these issues, it is essential to reduce plastic production, promote long-lasting products, and improve recycling practices to minimize plastic waste and its detrimental effects on ecosystems and biodiversity.

Plastic alternatives are not always eco-friendly
Plastic is a man-made material composed of molecules not found in the natural world. It is tough, flexible, durable, impervious to corrosion, and versatile. However, it is not eco-friendly because it is engineered not to break down and, therefore, accumulates in the environment.
There are many plastic alternatives available, such as glass, stainless steel, and algae-based replacements. Glass is easily recycled and can be used for storing food and drinks. Stainless steel is tough, easy to clean, and can be used for food and beverage storage. Algae-based replacements have similar properties to plastic but without the same environmental downsides.
However, plastic alternatives are not always eco-friendly. Biodegradable plastics, for example, are intended for short-lived use but often stay in the environment for a long time before they degrade. They are also often made from plants, which can contribute to food waste. In addition, the methods for testing biodegradability may not reflect real-life conditions, so it is uncertain whether these plastics will actually biodegrade in the natural world.
Furthermore, the recycling process for eco-friendly plastics is not always straightforward. Bioplastics, for example, cannot be recycled through the same avenues as traditional plastics and must be sent to industrial composting centers, chemical recycling plants, or anaerobic digesters. This creates a problem with proper disposal because bioplastics look very similar to traditional plastics. As a result, bioplastics can contaminate loads of traditional plastics, degrading their resale value.
Therefore, while plastic alternatives can be more eco-friendly than traditional plastics, they are not always without their environmental impacts. It is important to consider the full life cycle of these materials, from production to disposal, to understand their true environmental cost.
