Ozone Depletion
Ozone depletion refers to the thinning of the ozone layer in the Earth's atmosphere, which protects us from harmful ultraviolet (UV) radiation from the sun. This thinning is primarily caused by human-made chemicals, particularly chlorofluorocarbons (CFCs), used in products like aerosol sprays and refrigerants. When these chemicals reach the stratosphere, they release chlorine atoms that break down ozone molecules. As the ozone layer weakens, more UV radiation reaches the Earth, increasing the risk of skin cancer, cataracts, and negatively impacting ecosystems. Efforts, such as the Montreal Protocol, have promoted the reduction of ozone-depleting substances to help restore this vital layer.

Ozone depletion refers to the thinning of the ozone layer in the Earth's atmosphere, primarily due to human-made chemicals called chlorofluorocarbons (CFCs). The ozone layer plays a crucial role in protecting life on Earth by absorbing harmful ultraviolet (UV) radiation from the sun. When CFCs and similar substances reach the stratosphere, they break down ozone molecules, leading to an increase in UV radiation reaching the surface. This can cause health issues like skin cancer and cataracts, as well as environmental impacts. International efforts, like the Montreal Protocol, have been made to reduce these harmful chemicals and protect the ozone layer.
