This document discusses the connections between plastic pollution, climate change, and biodiversity loss. It argues that plastic pollution has become a planetary crisis due to the huge quantities of plastic entering the oceans each year. Most plastic pollution is invisible in the form of microplastics and nanoplastics that have broken off from larger debris. The production and degradation of plastic drives greenhouse gas emissions and is a major contributor to climate change. It also harms biodiversity through entanglement, ingestion and the introduction of toxic chemicals into ecosystems. The document calls for policymakers to address plastic pollution, climate change and biodiversity loss together as interconnected crises that threaten the stability of the planet.
