【plastics】Summary:
Plastics are synthetic or semi-synthetic materials that are widely used in modern society due to their versatility, durability, and low cost. They are derived from petroleum-based chemicals and can be molded into various shapes and forms. Plastics have revolutionized industries such as packaging, construction, healthcare, and electronics. However, their environmental impact, especially in terms of pollution and waste management, has raised significant concerns. The increasing use of plastics has led to a global crisis, prompting the development of biodegradable alternatives and recycling initiatives.
