**Plastics**

Plastics are synthetic polymers, typically derived from petroleum or natural gas, known for their versatility and durability. They are widely used in various industries, including packaging, construction, automotive, and consumer goods. The term "plastic" originates from the Greek word *plastikos*, meaning "capable of being molded," reflecting their malleable nature when heated or pressed.

Plastics are composed of long-chain molecules that can be shaped into different forms through processes like extrusion, injection molding, or thermoforming. Their properties, such as flexibility, strength, and resistance to moisture and chemicals, make them essential in modern manufacturing. Common types include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and polystyrene (PS), each with distinct applications.

Environmental concerns have grown regarding plastics due to their long degradation times and potential pollution. Many plastics do not biodegrade easily, leading to waste accumulation in landfills and oceans. Efforts to address this include recycling programs, biodegradable alternatives, and regulations to reduce single-use plastics.

The production of plastics also contributes to greenhouse gas emissions, as refining and manufacturing processes release significant carbon dioxide. Advances in sustainable plastics, such as those made from renewable resources or recycled materials, aim to mitigate these impacts. However, widespread adoption requires improved infrastructure and consumer awareness.
