Microplastics

What Are Microplastics and Why Are They a Big Deal?

Microplastics are tiny pieces of plastic that are less than 5 millimeters long, about the size of a sesame seed. Sometimes, they are so small that you need a microscope to see them! They come from larger plastic items that break down into smaller pieces, as well as from products like face scrubs, toothpaste, and even clothing. When we wash these products down the drain, they end up in our oceans, rivers, and soil.

Where Do Microplastics Come From?

Microplastics come from a few different places:

Bigger Plastics Breaking Down: Plastic bags, bottles, and packaging don’t decompose like natural things. Instead, they break down into tiny pieces over time, especially when exposed to sunlight and rough water.

Microbeads in Products: Some personal care products, like face washes and toothpaste, used to have tiny plastic beads in them. While many places have banned these microbeads, they’re still found in some products around the world.

Clothing: Synthetic clothes like polyester, nylon, and acrylic shed tiny fibers whenever they're washed. These fibers are small enough to slip through water filters and end up in water sources.

How Do Microplastics Affect the Environment?

Once microplastics get into the environment, they’re really hard to remove. They spread everywhere—from the deepest parts of the ocean to the top of the highest mountains! Animals can mistake these tiny plastics for food, which isn’t good for their health. When fish and other marine animals eat microplastics, they can feel full without getting the nutrients they need, making them weaker over time.

Are Microplastics Harmful to Humans?

Since microplastics have spread everywhere, they also end up in our food, water, and even the air we breathe. Scientists are studying whether microplastics could be harmful to us, too. Early studies suggest that tiny plastics could carry chemicals or harmful germs, which may affect our health if they build up in our bodies. While we don’t yet know all the risks, it’s likely not great to have plastic in our system.

What Can We Do to Reduce Microplastics?

We can help reduce microplastics by:

Using Fewer Single-Use Plastics: Instead of plastic bags, bottles, and straws, we can choose reusable items made of glass, metal, or cloth.

Choosing Natural Fabrics: When we wear cotton or other natural fibers, they shed fewer plastics into the water.

Recycling Properly: Recycling helps keep plastic out of the environment, where it might break down into microplastics.

Supporting Bans on Microplastics: Many places have banned microbeads in products. Supporting similar actions can help prevent new microplastics from entering our ecosystems.

Final Thoughts

Microplastics are tiny, but their impact is big. While it may seem hard to fight something so small, even small actions can make a difference! By making thoughtful choices about what we use and buy, we can help protect our environment and our health from microplastics.
