What Plastic Is
Composition: Primarily long chains of molecules (polymers) made from petroleum, coal, or natural gas, though some are plant-based.
Origin: The word comes from Greek, meaning "able to be shaped".
Properties: Versatile, durable, flexible, resistant to chemicals, and low-cost to produce, allowing it to be molded into countless forms (films, fibers, bottles).
Uses & Impact
Ubiquitous: Used in packaging (40% of production), construction, transport, electronics, and healthcare.
Revolutionary: Enabled advancements in medicine, space travel, and lightweight vehicles.
Environmental Harm: Doesn't biodegrade; instead, it breaks into tiny toxic microplastics that pollute soil, water, and air, harming wildlife and potentially humans.
Climate Contribution: Its energy-intensive production from fossil fuels releases significant greenhouse gases.
