The UN Environment Programme is looking to build a landmark treaty to combat plastic pollution. Scientists explain that microplastics have been found on the highest mountain peaks, in the deepest ocean trenches, and even in the human body.

Geneva

The United Nations is in the process of creating a global treaty to address the growing issue of plastic pollution. Everyday measures, such as choosing tap water over bottled and avoiding plastic containers for food, are being adopted by some individuals to reduce exposure to microplastics. Scientists warn that microplastics, which result from the breakdown of plastics, are now present in nature and the human body, with potential health risks including fertility issues, cardiovascular problems, metabolic diseases, and cancer. Experts recommend using plastic-free products and regularly aerating rooms to minimize inhalation of microplastic particles, which have been detected in human lungs. Research suggests that people could be ingesting up to 68,000 plastic particles daily, underscoring the urgency of international action.

Fighting plastic pollution: UN's landmark treaty in the making

Choose tap water rather than bottled. Cook at home and when reheating food in the microwave don't do it in a plastic container. Everyday routines that can reduce our exposure to microplastics that some Parisians have begun to adopt. When I buy milk or whatever and I have a choice I go for a cardboard container rather than a plastic one. I drink tap water so generally I carry a reusable water bottle. You have to be careful and it can get tiring but it's got to be done. Microplastics are tiny particles that come from the breaking down of plastics which accumulate in and contaminate nature and make their way into our bodies. Scientists recommend choosing plastic free cleaning products and cosmetics not always an easy thing to check on a label. They also advise aerating rooms regularly to avoid inhaling particles because they've also been found in our lungs. We eat, breathe and drink microplastics potentially with serious consequences to our health. Fertility problems in both men and women, cardiovascular problems, metabolic diseases, cancer. A slow ubiquitous poison. Scientists say we could be ingesting up to 68,000 particles of plastic per day.
