The ecological perspective views synthetic polymerization as a modern crisis. Since these synthetic chains are highly resistant to bacterial breakdown, they accumulate in our oceans, soils, and even our own bloodstreams as microplastics. Environmental scientists urge a rapid transition toward biodegradable and bio-based polymers. These are engineered to contain weak links in their backbones, allowing natural microbes or water to easily snap the chains back into harmless organic pieces.
