Ozone Layer Depletion
Ozone layer depletion refers to the gradual reduction in the concentration of ozone (O₃) in the Earth's stratosphere. The ozone layer plays a crucial role in protecting life on Earth by absorbing most of the sun's harmful ultraviolet (UV) radiation. When this layer is depleted, more UV radiation reaches the Earth's surface, leading to various environmental and health problems.
One of the primary causes of ozone depletion is the release of chlorofluorocarbons (CFCs), halons, and other ozone-depleting substances (ODS) into the atmosphere. These chemicals, commonly used in refrigerants, air conditioning systems, and aerosol propellants, break down ozone molecules when they are released into the stratosphere. When CFCs are exposed to ultraviolet light, they release chlorine atoms, which then react with ozone molecules, breaking them apart.
