Envrionmental Impact Plastic Straws

Environmental Impact of Plastic Straws

Plastic straws are almost always used only once before being disposed of. Further, they really are non-essential (we can drink soda without right?). Plastic straws are single-use, lightweight, and made from Polypropylene, a material that isn’t easily recycled and degrades slowly. As a result, the negative environmental impact of plastic straws is disproportionate compared to volume.

At TRVST we want to encourage people to take actions preventing further harm to the environment from single-use plastics. You can take a small step every time you enjoy a meal out by asking for non-plastic straws with your drink or carrying your own reusable straws. Or none at all.

How many plastic straws do we use a day?

Plastic straws are the ultimate in single-use convenience. Typically we only use them for the lifespan of a single drink before they are discarded.

We go through a staggering 25.3 billion plastic straws in Europe every year11. In the US it is said that we use 500 million straws a day, a statistic that became viral after its release back in 2011. This number has played a leading role in exposing quite how wasteful we are with plastic straws.

It turns out that this number was originated by a 9-year-old from Vermont, Milo Cress. Milo undertook the research as part of his own personal campaign to reduce plastic drinking straw usage. He called a bunch of manufacturers and averaged out the responses he received to indicate the volume of straws Americans use every single day.

Check a 10-year-old Milo talking about his work below on CNN (go, Milo!):

Estimates Vary

Estimates of the number of straws used in a country as big as America vary considerably. Just imagine all those burger joints, eateries, cafes, and restaurants across the land (and the globe) serving drink after drink with plastic straws.

Freedonia Group estimates the number as being more like 390 million straws a day. Another study from Technomic estimates 170 million a day.

42 billion straws are used each year in the UK, or 115 million a day8. This is by far and away from the highest usage in Europe.

Whatever the actual numbers there’s no doubt at all that we get through a lot of straws. This all adds up to plastic straws being a big environmental problem.

People Starting to Take Notice of the Environmental Impact of Plastic Straws

Turtles and plastic straws

A few years after Milo created the 500 million statistic, Christine Figgener (marine biologist) filmed a now-famous video that caught the public attention. You can watch her removing a plastic straw from a poor unfortunate sea turtle's nose. Be warned it's an unpleasant watch.

Pretty harrowing stuff. Terrible for the turtle and all those affected since. On a more positive note however her video helped really propel the plastic straw issue into the public psyche.

That turtle basically became the poster turtle of the movement to encourage more and more people to use non-plastic straws.

In late 2017 the BBC first aired “Blue Planet II” featuring Sir David Attenborough, the follow-up to 2001’s award-winning show. The Blue Planet has helped raise public awareness of the plastic issue. David Attenborough tells the story better himself in the video below than we ever could, do watch:

Why are straws bad?

Plastics are everywhere. According to the United Nations, we have become addicted to single-use or disposable plastic. Plastic straw bans are now happening across the globe, and as such, their days might be numbered.

Single-use plastic straws are small, hollow, and light and don’t seem to take up all that much room. You might think, other than the sheer volume, that we have bigger things to worry about. To an extent, you’d be right.

Relatively straws are still a small part of the picture. Plastic straws make up around 7 percent of all the plastic waste we humans produce (land and sea) and considerably less by weight.

It’s not as simple as that, however. They’re definitely not dishwasher safe, and we don’t reuse them.

Where does all this plastic go? A leading scientific study notes that of the 8.3 billion metrics tons of plastic ever produced only 9% has been recycled6. This includes plastic straws and all sorts of other single-use plastics.

What happened to the rest? 12% has been incinerated. The majority at 79% ends up in landfills, dumps, or the natural environment.

Plastic Straws and our Oceans

How do plastic straws get into our oceans?

Part of the issue is that plastic straws often accompany a takeaway meal. People are found using them in their cars and by the sea making it less convenient to dispose of them in recycling bins at home or in restaurants.

It really isn’t too clever to be filling up our landfills with plastic we don’t really need to use. However, the environmental impact of plastic straws is arguably worse when they reach our oceans.

They are often thrown away, take away paper cups attached. How do they get there? Because of their lightweight plastic straws when disposed of often simply blow out of bins. Out of bins and into the waterways that lead to our oceans.

The same can occur when in a landfill.

Birds also add to the problem, scavenging over landfills and digesting straws. The straws they eat can stay in their stomachs until they die. As a result, they often then escape into waterways when birds decompose.

To quantify the overall plastic problem:

  • A massive 8 million tons of plastic10 (straws and more) enters our oceans each year7.
  • Major rivers around the world carry an estimated 1.15 - 2.41 million tons of plastic into the sea every year.

Plastic Straws are the 7th most collected waste item from beaches

In the UK the Great British Beach Clean cleaned 339 beaches of plastic waste in 2017. This effort resulted in over 250 thousand items of trash being picked up off British beaches. Of these 500 pieces were disposable trays, cutlery, and straws.

The same year the Ocean Conservancy rallied volunteers from 112 countries for their own beach cleanup. They further collected a staggering 18 million pounds of trash and plastic products from beaches. An amazing effort.

Amongst their haul of trash, they collected over 400 thousand plastic straws. Unbelievably, that’s plastic straws equivalent to 145 times the height of One World Trade Centre (New York, at 541 meters).

Their count found that straws (and stirrers) were the 7th top collected plastic item. Close behind caps, plastic bags, water bottles, and cigarette butts.

Sadly however this is only a fraction of the straws in our oceans. Despite their size, the environmental impact of plastic straws is a significant problem in our seas and on our beaches.

How many straws are actually on our beaches?

Denise Hardesty and Chris Wilcox, two Australian scientists set out to find out. They spent 5 years looking and assessing the waste collected on US shores. Their scientific research, published in 2015, found that there are around 7.5 million straws on America's coastlines.

The same team extrapolated that figure globally. As a result, they estimated that there are between 437 million and 8.3 billion plastic straws on the world’s beaches and shores. That's a whole lot of straws.

Do plastic straws biodegrade?

Unfortunately for the environment plastic straws do not biodegrade. Basically meaning that they do not decay naturally in a way that is not harmful. This is a key factor affecting the environmental impact of plastic straws on marine life and our oceans. They do however degrade over time. This means plastic straws break down into smaller particles. The resulting particles are named microplastics.

To add to this problem most plastic straws are made of polypropylene which degrades slowly9. In fact, they can take up to 200 years to break down. The resulting degradation has been found to never leave our seas. This means that it is almost impossible to eliminate plastic straws from the environment once they’ve reached our Oceans. Microplastics are so small they are virtually impossible to clean up. All this makes for a big issue caused by a whole lot of very small plastic pieces.

That's not the end of it, however. In addition, harmful toxic chemicals are also leached into the environment as those nasty little plastics degrade.

The Environmental Impact of Plastic Straws on the Oceans

By the year 2050 there will be more plastic in the ocean than fish
[ellen macauthur]

Plastic-strewn beaches are unsightly and can turn the stomach. This mess often ruins the beauty of our beach visits or time on the water.

Worse is what happens out of most people’s sight. Plastics straws are often washed together with other plastics as a result of their lightweight. As they are collected together they can easily accumulate into huge ocean garbage patches.

Bringing them together are Ocean gyres. A large vortex or circular movement of the ocean which is a natural phenomenon as a result of ocean currents and the earth's movements. These big natural whirlpools suck plastic into sometimes massive collections of our trash. Plastics collected together break down even more slowly as a result of not being isolated and more exposed to more of the ocean's elements. It's almost as if they protect each other making matters worse.

Massive ocean garbage patches

The worst of these plastic collections is the well documented Great Pacific Garbage Patch (GPGP).  It's located halfway between Hawaii and California, occupying an area of 1.6 million square kilometers. That’s twice the size of France. The mind just boggles how difficult it is going to be to clean up an area that big on the water.

Watch The Great Pacific Garbage Patch Explained by The Ocean Cleanup to find out more.

84% of plastic surveyed12 in this huge mess was found to contain Persistent Bioaccumulative Toxic chemicals (PBT’s). PBT’s are basically really nasty chemicals.

According to Wikipedia “[their], high toxicity and persistence have the ability to destroy and/or irreparably damage trophic systems.” Trophic Systems is a term referring to the parts and levels of our food chain. And to avoid problems later down the line with the food we all need to survive these systems all need to work together.

What is the effect of plastic straws on marine life?

As if all that wasn’t bad enough the environmental impact of plastic straws goes beyond the mess we’ve made. Single-use plastics and a lot of straws are also impacting marine life and other animals.

Marine debris, three-quarters of which is plastic, is negatively affecting more than 800 animal species and costing economies millions.
(The United Nations Environment Programme, 2016)

Of course, it’s pretty hard for many species of marine life to swallow a straw. It does, however, happen sometimes especially with the small straws on cardboard drinks containers. Larger plastics tend to disproportionately affect Sea Turtles and Seabirds. Because these animals do in fact mistake these items for food.

Microplastics, on the other hand, can float forever. They persist in the Oceans until some poor marine animal swallows them. They are almost microscopic particles and hard to discern from normal food in the marine environment. Ingested plastics can then stay in the gut of the fish or animal that has swallowed them until passed at death. Scarily they don’t degrade entirely ever. Marine animals with plastic in their guts can then also be eaten by other creatures on the food chain passing the problem from one animal to another.

Plastics straws harm marine life

So do plastic straws really actually harm our marine life? To study the impact of plastics on marine life academics from The University of Georgia collected 96 baby turtles3 from beaches around Florida. Published findings from their research noted that all of the turtles in the sample had ingested plastic. Sadly around half of the turtles in the study died. The team theorized was likely a result of the plastic in their systems.

Meanwhile in the North Pacific alone, according to the Centre for Biological Diversity, fish ingest somewhere between 12000 and 20000 tons of plastic each year. Whilst 56% of cetaceans (whales, dolphins, and porpoises) were found to have ingested marine debris. Three-quarters of marine waste is plastic.

Turtles, seabirds, and fish who have consumed plastic can die of starvation. These undeserving creatures think that their stomachs are full and fail, through no fault of their own. to eat the food they actually need1. Aside from killing these creatures with our plastic mess, we’re polluting a vital part of our own food chain.

What of the impact on our food?

There is a small amount of good news. The Food and Agriculture Organization of the United States found that the effect of microplastics on humans was negligible2.

This is as a result of the majority of these little particles being found in the guts of the fish we eat. Of course, most people only eat the white flesh of fish. The guts are removed and discarded with the plastics in them not making their way into our bodies.

Another study from 2018, led by the University of Vienna, found the opposite:

more than 50% of the world population [of Humans] might have microplastics in their stools5”.

Contrary findings are often the case when researching external impacts on large and complicated systems. The study, notably, researched only a small sample. working with only eight people from Europe, Japan, and Russia. The authors clearly note that larger studies are required to further validate their findings. All the same, it’s clear the environmental impact of plastic straws is harming our food chains.

Say no to straws to reduce your environmental impact

It probably comes as no surprise that our oceans are important to life on our planet. The importance of the Oceans goes well beyond the fish we eat. Did you know that our oceans produce over half of the world’s Oxygen and absorb 50 times more carbon dioxide than our Atmosphere4?

As a result of plastic waste, we’re poisoning the water and the marine life in it.

It's recognized that the Great Pacific Garbage Patch is a highly visible indicator of quite how bad this all is. And for certain straws are only a small part of the overall mass. Yet the fact still remains that we need to work together to address each and every plastic waste contributor urgently.

To do so will involve governments, huge resources, and change at a massive scale.

Is there an answer? The Marine Conservation Society notes that the best solution to mitigate the environmental impact of plastic straws is preventing them from even entering our Oceans. Simple and clear.

Take Action

Each of our actions can make a small difference. If we all choose to carry reusable straws we'd alleviate the flow of this plastic waste culprit into our seas.

Every single-use plastic straw we save from entering our Oceans is an improvement on the status quo. Also by asking for non-plastic straws when eating out, you can make a small a simple step in the right direction. This, in turn, reduces the need for restaurants to stock plastic straws in the first place and at best stop serving them by default.

We, humans, have had a long history with plastic straws and it's one we hope is coming to an end. At TRVST we’re encouraged by initial progress to phase out plastic straws. Needless to say, there’s a lot more we all have to do to co-create the change that will protect our environment for future generations.

Meanwhile, at TRVST, our focus is on individual and collective action. Action we can all participate in. Because it’s time to remove straws from the picture.
