Understanding Polymers

Polymers are large molecules made of repeating monomers, essential in both natural and synthetic forms. Natural polymers include DNA, proteins, and cellulose, while synthetic ones like Bakelite and Silly Putty have revolutionized industries. However, synthetic polymers pose environmental challenges, as they do not biodegrade easily, leading to pollution and health concerns. Understanding polymers' roles and impacts is crucial for sustainable development.
