Why Plastic is bad for the Environment and People (and how to go Plastic-Free)

11 September 2025

This blog will help you dive into the eye-opening reality of plastic pollution’s effects on our environment and health, and discover actionable steps to embrace a plastic-free lifestyle for a brighter, greener future.

Plastics are everywhere in our daily lives, but people are becoming more and more aware of how bad they are for the environment. Every year, more than 8 million tonnes of plastic enter the oceans, and only a small portion is recycled.¹ You can see plastic littering streets, rivers, and beaches, but it’s also increasingly being found in our food, water, and even the air we breathe.²

Plastic feels impossible to escape because it’s everywhere in our daily life, from the clothes we wear to the food we eat. We have become reliant, and almost addicted, to the convenience of plastic.

Plastic in itself is not even the real problem, as it can have many beneficial uses. The real issue is overconsumption and a throwaway culture. Why are we using a material that lasts hundreds of years for packaging and bags thrown away after a single use?

To give an indication, one million plastic bottles are purchased every minute worldwide, while up to five trillion plastic bags are used each year.³ But those are just the most visible uses of plastics – they are also in our clothing, packaging, and cigarettes, all of which often end up in landfill.

The good news is that with a few lifestyle and shopping changes, you can cut out most plastic from your life. You just have to know where to start, and be willing to make some changes!

This guide explores why plastic is so damaging to the environment, wildlife, and human health, and then shares the main practical principles to help you start your plastic-free journey.

16+ Reasons Why Plastics Are Bad

The same properties that make plastics useful — their durability and resistance to degradation — also make it nearly impossible for nature to decompose them.

Most plastic items never completely disappear, they just break down into increasingly smaller pieces until they become microplastics.³ Microplastics are tiny fragments of plastic less than five millimetres in size, often impossible to see with the naked eye.

And microplastics aren’t just released when we throw our waste away irresponsibly. Simply washing synthetic clothing (which is most of the clothing in the world) sheds an estimated 700,000 microplastics with every laundry wash.⁴ It is estimated that 5.6 million tonnes of synthetic microfibers having entered the environment since 1950 from washing our clothes alone!⁵

So how does all this plastic waste and microplastics affect environment, wildlife, and human health?

The Harmful Effects of Plastic on the Environment

Plastic in the Oceans

Plastics are incredibly damaging to our environment, especially our oceans and ecosystems.

There are about 500 times more plastic particles in the oceans right now than there are stars in our galaxy, about 51 trillion microplastic particles!⁶
This massive volume of plastic waste chokes marine habitats and disrupts the balance of important ecosystems like coral reefs which can threaten their survival.

Plastic on Land

Plastic does not just pollute oceans, but is also affecting habitats on land.

Plastic waste clogs waterways and contributes to flooding, which disrupts both human and animal habitats.³
Microplastics contaminate soil and water sources, which reduces the number of essential species that live below the surface, which in turn leads to less fertile soil and land.⁷
While wastewater treatment plants have become very good at capturing microplastics, they often apply the leftover biosolid sludge (which includes the captured microplastics) to croplands or bury them landfills, so they re-enter the environment anyway.⁴

The Harmful Effects of Plastic on Animals

Plastic and Ocean wildlife

Wildlife around the world is suffering severely from the impact of plastic pollution.

Many animals often mistake plastic waste for food, which can lead to internal injuries, digestive blockages, exposure to toxic substances, and even starvation.¹ Especially marine animals are at risk, and many species, including many endangered ones, have been found with plastic in their stomachs.
Microplastics from clothing are extra challenging because they can escape from wastewater treatment plants and are ingested by marine life.⁵
Microplastics have been found in 86% of sea turtles, 44% of seabirds, and 43% of marine mammals.⁷
Marine creatures like turtles and seals also become entangled in discarded fishing nets and plastic packaging, resulting in injury or death.

Plastic and Animals

Animals on land are affected in similar ways by plastic pollution.

Large mammals like elephants and camels are already dying from ingesting plastic, which can block their intestines and cause fatal internal injuries.⁷
Smaller animals, such as raccoons and birds, often get entangled in plastic waste, leading to injuries or death.⁷
And again, microplastics contaminate food and water sources, which poisons the animals that rely on them.

The Harmful Effects of Plastic on Human Health

All those microplastics that enter the environment eventually make their way to people.

Microplastics are now being found in everyday foods and beverages, including seafood, salt, and even drinking water.² This means that we are ingesting and inhaling microplastics on a regular basis!
Once inside the body, microplastics can invade cells and tissues in major organs which disrupts cellular processes, and potentially depositing harmful chemicals. Microplastics can carry harmful pollutants and pathogens, which can lead to toxic effects when ingested.
Recent studies have found microplastics in our blood, attached to our organs, in human placentas, and in human testicles!^{2, 8}.
Researchers have said that microplastics could contribute to declining fertility issues, sperm counts, genital malformations, and testicular cancer.⁸ Other studies suggest that microplastics can cause inflammation, disrupt endocrine functions, and may be linked to certain cancers.²

While some of these effects are still being researched, it’s definitely an icky idea that there are so many microplastics in our bodies…

The 5 Principles of Going Plastic-Free

Now that the gloomy facts behind plastic pollution are out of the way, we can focus on the way we can fight it. While plastic is definitely an industrial-scale problem, there are many things you can do at home and with your buying habits that can help you remove the plastics in your life.

As mentioned before, the real problem to overcome is changing our overconsumption and disposability mindset to one of reduce and reuse. Replacing plastic products with, for example, glass or aluminium, makes little difference if they are still treated as disposable, even when they are recycled.

You’ll find that most tips for plastic free living centre around replacing plastic products with reuse habits and buying for long term and high quality. It’s also about simply buying less and using what you already have as much as possible.

The less plastic you buy, the more you signal to businesses that we demand change. If you do need to buy plastic, make sure you recycle it to minimise the chance of it ending up in the environment!

1. Swap out Single-Use Plastics

One of the best places to start for going plastic free is ditching single use plastics. Plastic bags, bottles, and straws are some of the most common sources of plastic waste and are easily replaced by better options.

For example, try eco-friendly alternatives such as reusable shopping bags, stainless steel water bottles, and bamboo or metal straws (or simply no straws). Buying them once and using them over and over again prevents a massive amount of plastic waste!

2. Plastic-Free Shopping

Another big plastic waste category is packaging, especially with grocery shopping. While plastic packaging isn’t always avoidable with food, there are small habits you can try that can help minimise the amount of plastic packaging you have to buy.

One effective strategy is to shop in bulk, which reduces the need for individual plastic-wrapped products. For example, I started buying 10kg bags of rice which lasts me about a year, instead of the little bags I had to buy every other week! (It saves a lot of money too)

You can also bring your own reusable grocery bags and produce bags, and pick unpackaged vegetables and fruits when they are available. Most fruit and veg doesn’t actually need plastic packaging to stay good.

Additionally, try finding and supporting brands and stores that offer plastic-free packaging options, and the possibility to bring your own reusable containers to store bulk items like grains, nuts, and spices. Farmers’ markets are also great places to find fresh produce without plastic packaging.

3. Natural Clothing

Choosing clothing made from natural fibres such as organic cotton, hemp, and bamboo helps reduce reliance on synthetic fabrics, which shed microplastics during wear and washing.

Sustainable materials not only benefit the environment but also offer better breathability and comfort, and are more durable.

When shopping for new clothes, look for labels that indicate the use of 100% sustainable materials and ethical production practices, and avoid synthetic fibres like polyester, nylon, and acrylic. Investing in quality, long-lasting clothing rather than fast fashion can also reduce overall consumption and waste.

4. Plastic-Free Household Products

Switching to plastic-free alternatives for household products is another effective way to reduce plastic waste. Look for cleaning supplies, toiletries, and kitchenware that come in minimal or biodegradable packaging.

For example, choose bar soap instead of liquid soap in plastic bottles, and opt for glass or metal containers for food storage instead of plastic ones. There are also many plastic-free versions of cleaning tools such as cleaning brushes, sponges, and dust pans.

5. Embrace DIY and Repurposing

Embracing a DIY mindset can help you find creative ways to repurpose items instead of discarding them.

For example, old clothes can be turned into cleaning rags, glass jars can be used for storage, and plastic containers can be upcycled into plant pots.

DIY projects not only reduce reliance on new plastic products and prevent plastics from going to waste, but also allow for creative expression and resourcefulness.

Conclusion

Hopefully it is obvious by now that reducing plastic consumption is crucial for the well-being of our planet and future generations. Plastic pollution severely impacts wildlife, both in in the ocean and on land, and possesses significant risks to human health through the ingestion of microplastics.

By making conscious choices, such as reducing single-use plastics and choosing natural fibres in clothing, we can significantly reduce the impact of plastics and microplastics on our environment.

Also remember that less is more – consuming (and wasting) less has as much of an environmental impact as choosing the right products. You really don’t need 10 new outfits every season or buy the latest trendy product – instead, invest in quality, sustainability made products that you can enjoy for years to come.

It’s not about going completely plastic-free, as that’s pretty much impossible and it’s not the point. But every small action counts, and together, we can protect our planet for future generations
