# Microplastics pose a major risk to the climate and marine wildlife

Trillions of microplastic particles in the ocean pose a serious threat to marine life, from large filter-feeders to tiny plankton. While not immediately lethal, their long-term effects on plankton and marine microbes could disrupt vital Earth systems, such as ocean carbon storage and nitrogen cycling. These effects could hinder the planet's ability to mitigate atmospheric CO2 increase. Unfortunately, removing small plastic particles from the ocean with current technology is impossible, making pollution prevention a top priority. A UN treaty to address plastic pollution offers hope, but the growing plastic production remains a concern. The international community must take action to safeguard our oceans.
