Part 5/10:
Recent studies have aligned plastic pollution with critical ecological limits known as planetary boundaries. These boundaries quantify safe operating space for humanity regarding various environmental indicators, including climate change and biodiversity. Notably, plastic pollution has been shown to interface directly with several of these boundaries, notably biospheric integrity and biogeochemical flows. Despite our perception of plastic pollution as primarily an aesthetic concern, its ramifications are deeply woven into the fabric of global sustainability challenges.
