What does CFCs refer to in environmental science?

CFCs stands for chlorofluorocarbons, which are a group of human-made chemical compounds that consist of chlorine, fluorine, and carbon. They were commonly used as refrigerants, propellants in aerosol sprays, and solvents in the manufacturing process. The significance of CFCs in environmental science primarily arises from their impact on the ozone layer; when released into the atmosphere, these compounds can break down ozone molecules, leading to ozone depletion. This depletion allows more harmful ultraviolet (UV) radiation from the sun to reach the Earth's surface, which can result in increased incidences of skin cancer and other environmental issues.

Understanding CFCs is crucial due to international efforts, like the Montreal Protocol, aimed at phasing out substances that harm the ozone layer. The knowledge of their properties and effects on the environment helps guide policies and practices in various industries to protect ecological health.
