Ozone Layer
The ozone layer is a region of Earth's stratosphere, about 10 to 30 miles above the surface, where a high concentration of ozone (O₃) gas occurs. It plays a crucial role in protecting life on Earth by absorbing the majority of the sun's harmful ultraviolet (UV) radiation. Increased UV exposure can lead to skin cancer, cataracts, and harm to ecosystems. Human activities, particularly the use of chlorofluorocarbons (CFCs), have depleted the ozone layer, prompting global efforts to reduce such chemicals and protect this vital shield for future generations.

The ozone layer is a region of the Earth's stratosphere that contains a high concentration of ozone (O₃) molecules. It plays a crucial role in protecting life on Earth by absorbing most of the sun's harmful ultraviolet (UV) radiation. This shielding effect helps prevent skin cancer, cataracts, and other health issues, as well as protecting ecosystems. The ozone layer has been threatened by human-made chemicals, like chlorofluorocarbons (CFCs), which have caused significant depletion. International efforts, such as the Montreal Protocol, have aimed to reduce these harmful substances and aid in the recovery of the ozone layer.
