Microplastics, tiny pieces of plastic less than 5 millimeters in length, are a major source of pollution in the environment. They can come from a variety of sources, including plastic bags, bottles, straws, and clothing fibers. Microplastics can be harmful to wildlife, as they can be ingested and can cause blockages or damage to the digestive tract. They can also absorb toxic chemicals from the environment, which can then be transferred to animals that consume them.

A new study from the University of California, Santa Barbara, has found that microplastics with rough surfaces can be even more harmful to wildlife than microplastics with smooth surfaces. The study, published in the journal Environmental Science & Technology, found that rough microplastics were more likely to cause damage to the cells of mussels, a common marine invertebrate.

The researchers believe that the rough surfaces of microplastics may cause damage by creating tiny tears in the cells of mussels. These tears can then lead to cell death and can eventually affect the health of the entire organism.

The study's findings suggest that rough microplastics may pose a greater risk to wildlife than smooth microplastics. This is important information, as it can help us to better understand the potential risks of microplastics and to develop strategies to reduce their impact on the environment.

Here are some things that you can do to help reduce microplastic pollution:

* Avoid using single-use plastics, such as plastic bags, bottles, and straws.

* Recycle plastic whenever possible.

* Properly dispose of plastic waste.

* Support organizations that are working to reduce plastic pollution.

By taking these steps, you can help to protect wildlife and the environment from the harmful effects of microplastics.
