Plastics are everywhere in our daily lives. We produce vast
amounts of plastic, and that number is growing rapidly. In 2020 alone, the
world produced 398 million metric tons, and production is expected to double or
even triple by 2050. While plastics can offer advantages over other
materials—such as in medical applications, lightweight vehicle components, and
electronics—a significant portion is designed for single use, serving its
purpose for only minutes yet persisting in our environment for centuries. What
was once a convenient material has now evolved into more than just an
environmental concern—it has become a growing public health emergency affecting
us all.

We often think of plastic as a problem only after it has
been used, focusing on how to dispose of it. However, plastic causes harm at
every stage of its lifecycle. More than 98% of all plastic is derived from
fossil fuels like oil and fracked gas, and its production carries the same
health risks associated with fossil fuels.
Plastic production facilities are often located in or near
marginalized communities. A well-known example is Cancer Alley, an 85-mile
stretch of land in Louisiana along the Mississippi River, between Baton Rouge
and New Orleans. Cancer Alley is home to over 150 petrochemical plants and
refineries, many of which produce the chemicals used to make plastic. This
region has some of the highest cancer rates in the U.S. People living
here—predominantly low-income Black communities—suffer from health problems like
cancer, respiratory diseases, and reproductive issues due to the toxic
emissions from plastic manufacturing. This situation highlights how plastic is
both a public health and environmental justice issue.
Unlike organic materials, plastic does not biodegrade.
Instead, it breaks down into smaller and smaller pieces of plastic, eventually
becoming microplastics and even tinier nanoplastics—some as small as viruses.
These plastic particles contaminate soil, water, and air, where they are
absorbed by plants and ingested by both marine and land animals. In turn, we
are exposed to microplastics through the food we eat, the water we drink, the
air we breathe, and even through skin contact.
Much of this exposure comes from everyday sources. Plastic
food packaging sheds microplastics into our food, especially when exposed to
heat, oil, or acidity. Synthetic fabrics release microplastics into the air and
water during wear and washing. We can absorb microplastics from personal care
products and cosmetics through our skin. Even indoor air carries microplastics,
released from the plastic-based materials in our homes.
There are at least 16,000 known chemicals used in plastics
to give them specific properties, such as increased flexibility, improved heat
resistance, color, flame retardancy, UV protection, enhanced durability, and
softness. Many of these chemicals have not been tested for health effects, and
among those that have, a significant number show harmful impacts. Some are
known to be endocrine (hormone) disruptors, carcinogens, and neurotoxins,
interfering with essential biological processes in our bodies. Studies have
found microplastics and the harmful chemicals they carry in breast milk,
placentas, brains, hearts, kidneys, livers, lungs, and blood. These exposures
are linked to increased rates of infertility, cancer, diabetes, obesity,
asthma, coronary heart disease, and neurological disorders like autism and
ADHD. The effects are particularly harmful for developing fetuses, young
children, and adolescents going through puberty.
Additionally, these health problems come with a financial
burden. A recent study published in the Journal of the Endocrine Society
estimates that healthcare costs attributable to chemicals in plastics in the
U.S. amount to $250 billion annually.
The plastics industry has long promoted recycling as the
primary solution to plastic waste, often to reassure consumers about plastic’s
sustainability. However, less than 10% of all plastic ever produced has been
recycled, and in the United States, the annual recycling rate is less than 6%.
The rest ends up in landfills, incinerators, or the environment, including our
oceans. This isn’t due to a lack of effort by consumers, but rather because
plastic is inherently difficult to recycle. Virgin plastic is cheaper to
produce than recycled plastic, and the sheer variety of plastic types
complicates sorting and processing. Additionally, the chemicals added to
plastics can render them unsuitable for reuse. Unlike glass, aluminum, and
steel—which can be recycled indefinitely without quality loss—plastic degrades
with each recycling cycle and can typically only be recycled once or twice. The
recycling process itself can also release harmful chemicals, and additional
chemicals are often introduced when creating new plastics.
Rather than relying on recycling, we need to shift our
focus. Eliminating unnecessary single-use plastics and embracing reusables is
key. We must also transition to safer, more sustainable materials that don’t
contain harmful chemicals.
What can you do to help? First, educate yourself and inform
others about the dangers of plastics. Many people don’t realize the extent of
harm caused by plastic. Share the facts with your friends, family, and
colleagues.
Second, reduce your plastic use. Start with the most
problematic plastics—switch to a reusable water bottle instead of single-use
plastic ones. Bottled water is a major contributor to plastic pollution, and it
is generally not considered higher quality than tap water. In fact, it contains
more microplastics than tap water and can be expensive.
Bring reusable bags when shopping instead of using
single-use plastic ones. In the U.S., the average person uses over 300 plastic
bags per year. In Illinois alone, this adds up to more than 3.7 billion plastic
bags polluting our environment and harming our health each year.
Once these habits become second nature, find additional ways
to reduce plastic waste. Buy less and choose durable, reusable items over
disposable ones. Repair rather than replace broken items when possible. Borrow
what you need, and shop secondhand to reduce the demand for new plastic
products and packaging. Opt for plastic-free personal care products and make
your own cleaning solutions with simple ingredients like vinegar, baking soda,
and castile soap. Consider alternatives to plastic food storage, such as glass
containers or beeswax wraps. When shopping, visit farmers' markets or bulk
stores with your own containers. Bring reusable containers to restaurants for
leftovers. Whenever possible, choose products with minimal or no plastic
packaging.
Finally, advocate for change. Contact your legislators and
urge them to support policies that reduce plastic production, eliminate
single-use plastics, and hold manufacturers accountable for waste management.
Encourage local, state, and federal governments—and businesses—to cut plastic
use and eliminate harmful materials like polystyrene foam. Support companies
that are leading the way in reducing plastic.
Despite overwhelming evidence of harm, we are not powerless.
Everyday actions—reducing plastic use and advocating for stronger
legislation—can drive systemic change. By cutting plastic production and
promoting healthier alternatives, we protect both our health and the planet.
Together, we can create a cleaner, safer world for future generations.
