Ozone depletion is the gradual thinning of the Earth's protective ozone layer in the stratosphere, primarily caused by human-made chemicals like chlorofluorocarbons (CFCs). This process allows more harmful ultraviolet (UV) radiation from the sun to reach the surface, leading to increased health risks such as skin cancer and environmental damage to marine life and agriculture. In today's context, it's a rallying point for international environmental agreements, highlighting humanity's role in reversing planetary harm.
