A new UN partnership announced on Wednesday aims to raise awareness about the environmental and health impacts of microplastics in cigarette butts, the most discarded waste item worldwide. The UN Environment Programme (UNEP) and the Secretariat of the World Health Organization Framework Convention on Tobacco Control (WHO FCTC) will launch a social media campaign to highlight the issue. The partnership is facilitated through UNEP's Clean Seas campaign, a global coalition comprised of 63 countries devoted to ending marine plastic pollution. It combines the two agencies' respective experience on the health and policy dimensions of tobacco products, and research and advocacy on plastic pollution. Globally, more than six trillion cigarettes are produced annually, each containing filters, or butts, that are mainly composed of microplastics known as cellulose acetate fibres. However, cigarette butts that are not properly disposed of get broken down by factors such as sunlight and moisture, thus releasing microplastics, heavy metals and many other chemicals which impact ecosystems' health and services. Cigarette butts account for more than 766 million kilogrammes of toxic trash each year. They are also the most common plastic litter on beaches, making marine ecosystems more susceptible to microplastic leakages. When ingested, the hazardous chemicals in microplastics cause long-term mortality in marine life, including birds, fish, mammals, plants and reptiles. These microplastics also enter the food chain and are associated with serious human health impacts, which can include changes to genetics, brain development, respiration rates and more. The social media campaign will aim to engage influencers, as well as UNEP's Goodwill Ambassadors and Young Champions of the Earth. It will also include a political advocacy angle by highlighting a recent European Union directive that requires all tobacco products with plastic filters to be labelled clearly. The goal is to encourage the public to advocate for similar changes globally. "The Secretariat of the WHO FCTC has the technical expertise of the impact of tobacco products on not just human health but also on environment," said Atif Butt, UNEP's Chief of Public Advocacy. "By joining UNEP's and the Secretariat of the WHO FCTC's expertise together under the Clean Seas activation on microplastics, we aim to highlight how our health is intrinsically linked to that of our planet." — UN News
