A recent paper marks 20 years since the identification of microplastics, highlighting their widespread presence in the environment, wildlife, and human bodies. Research indicates that microplastics, which are plastic particles smaller than 5mm, pose toxic risks across various biological levels. They originate from multiple sources, including cosmetic products and the breakdown of larger plastics. Studies reveal that millions of tons of microplastics enter oceans annually, with even greater leakage on land. While they have been found in many food and drink products, concerns about their health effects—including inflammation and potential cancer risks—remain under investigation. The urgent call for global action emphasizes the need for new policies, such as the UN’s Global Plastics Treaty, to effectively address the microplastic crisis.
