Polymerization presents a deep philosophical irony. We took inspiration from nature’s temporary, degradable polymers to build synthetic materials meant to last forever. We solved the problem of material scarcity and decay by creating an era of plastic permanence. But in doing so, we disrupted the natural cycle of death and decay. We created objects designed for minutes of use that outlive us by centuries. It is a monument to our short-term thinking carved in indestructible chains.
