Humanity has entered the 'Plastic Age' by mastering synthetic polymers. While natural polymers like wood, wool, and silk built early civilizations, synthetic plastics like polyethylene and nylon redefined modern life. But this blessing is also a curse. Because these synthetic molecular knots are so strong and stable, our planet's decomposers do not know how to untangle them. This has led to a global waste crisis, forcing us to rethink how we use and discard these materials.
