Scientists studying human placentas have made a concerning discovery that highlights the ongoing impact of plastic on our planet. Research conducted on 62 placentas revealed the presence of microplastics in all of them, with the most frequently detected type being polyethylene, commonly used in single-use bags and bottles.

The fact that microplastics were found in human placentas raises alarm bells, as it suggests potential impacts on all mammalian life. "If we are seeing effects on placentas, then all mammalian life on this planet could be impacted. That's not good," expressed University of New Mexico professor Matthew Campen.

The findings, published in the journal Toxicological Sciences, indicate a troublesome impact on human health. While the specific effects of microplastics are still being investigated, research suggests their association with DNA damage, immune and metabolic system issues, and even a rise in inflammatory bowel disease, declining sperm counts, and colon cancer diagnoses in people under 50.

What makes the presence of microplastics in placentas particularly worrisome is that the organ develops over a relatively short period of eight months during pregnancy. In contrast, other organs accumulate particles over much longer periods of time.

Microplastics have also been found in other human organs such as the heart and blood, lungs, and other tissues, further emphasizing the pervasive nature of this issue.

Efforts are being made to limit exposure to microplastics and reduce plastic waste. Researchers are exploring technologies such as specialty water filters and plastic-eating bacteria. However, the most effective way to support these efforts is by rethinking our relationship with plastic.

The United Nations Environment Programme highlights the staggering statistics of plastic consumption, with one million plastic bottles being bought every minute and up to five trillion plastic bags used globally each year. By switching to reusable bottles and grocery bags, we can play a role in reducing the toxic plastic waste that eventually breaks down into these concerning microplastics.

As new technologies evolve, it is crucial to adopt sustainable practices and reduce our reliance on single-use plastics. Protecting human health and the well-being of all mammalian life on our planet hinges on addressing the pervasive problem of microplastics.
