For a long time, environmental pollution caused by plastics has been a cause for concern. However, our focus has primarily been on visible effects, such as gigantic plastic waste islands in oceans or the suffering of marine animals. But have you ever considered the microscopic plastic particles that could penetrate our bodies? New research suggests that microplastics, these tiny particles, may be just as, if not more, hazardous to us, humans.

Why are microplastics, particles smaller than 5 mm, raising concerns for human health? They are literally everywhere: in the air, in water, in our food. While their omnipresence has been a cause for concern, it's only recently that we started viewing them as a potential threat to human health. A group of scientists from the University of Rhode Island delved into this issue, conducting studies on mice of various ages. Their findings are worrisome.

Changes in the behavior of mice exposed to microplastics resemble symptoms of human dementia, with the intensity of these symptoms particularly pronounced in older individuals. These results prompt reflection on the long-term effects of human exposure to microplastics and whether certain groups of people may be more susceptible to their harmful effects.

Professor Ross, leading the study, noted that the observed reactions in mice were not caused by large doses of microplastics. This implies that even small amounts entering our bodies daily could be harmful. Microplastics were also found in virtually all examined organs, suggesting their widespread negative impact.

Dr. Chelsea Rochman emphasizes that we need to start thinking about microplastics as a pollutant whose impact on humans is not yet fully understood. This echoes situations from the past when certain substances, like asbestos, were considered safe until their long-term effects became apparent.

We cannot afford to wait. New research and innovative strategies to reduce the quantity of plastic waste are needed, as well as the exploration of sustainable alternatives to plastic products. Microplastics are not just an environmental problem; they pose a serious threat to our health.

Given these findings, it's time to start treating microplastics as a threat on par with other pollutants. We must act now to ensure a healthier future for generations to come. There's much work ahead, but we can counteract the effects of microplastic pollution if we take the right steps today.
