The plastic plague has taken a new turn, with artificial grass now contributing to the problem off one Spanish coast.
What is going on?
Researchers at the University of Barcelona recently made a jarring discovery after analyzing seawater off the coast of the city: high concentrations of fibers from artificial grass that are made of plastic, NewScientist reported.
In fact, artificial grass accounts for 15% of the larger plastics found in samples within about half a mile of shore.
The study excluded microplastics, focusing only on pieces 5 millimeters (or 0.2 of an inch) or larger. This is because it is more difficult to determine the origin of microplastics. The water samples were taken between 2014 and 2021.
The main author of the study, Liam de Haan, thinks that the large population of Barcelona combined with the city’s frequent use of artificial turf for sports probably accounts for the high numbers.
“We were really surprised that no one had reported this before,” he told NewScientist.
Why is artificial grass in the seas a concern?
While fake turf offers the advantage of saving water as it does not need to be irrigated, it is not exactly good for the environment.
First of all, it is made of polyethylene, a type of plastic. It only lasts for about 10-20 years, and it is difficult to reuse or recycle. As artificial grass breaks down, small pieces of plastic can make their way into soil and waterways, contributing to plastic pollution.
Ocean plastics like those near Barcelona threaten animals and ecosystems. For example, birds, whales, fish and turtles mistake plastic for prey. Their stomach can become coated with it, causing them to starve. They can also suffer from infections, cuts, internal injuries, and reduced swimming abilities, according to the International Union of Concerned Scientists.
In addition, artificial turf reaches higher temperatures than natural grass. It absorbs far more radiation than living vegetation, potentially contributing to global warming, according to the University of Plymouth in the UK.
What can I do to help with plastic pollution in the ocean?
Be careful not to use fake grass in your yard. In fact, you can skip a manicured lawn altogether, opting instead for a biodiverse lawn full of native plants.
You can also help curb plastic pollution by saying no to single-use plastics such as grocery bags, plastic wrap, straws, and coffee cup lids. Instead, invest in things like reusable bags, a steel straw, or a travel mug for your morning coffee.
You can also stop buying bottled water. Every year, nearly 20 billion plastic bottles are thrown away, according to the Natural Resources Defense Council. Keep a reusable water bottle with you — perhaps one with a built-in filter.
Other ways you can help include supporting a bag tax or ban in your local community, buying items in bulk, and recycling when possible.
