Explanation:
- The Earth is surrounded by a layer of gases known as the atmosphere, which protects it from harmful radiation from the sun and space.
- Ultraviolet (UV) radiation is a type of electromagnetic radiation with wavelengths shorter than visible light. It is harmful to living organisms, causing skin cancer, cataracts, and other health problems.
- The ozone layer is a region of the Earth's stratosphere that contains a high concentration of ozone molecules (O3).
- Ozone absorbs most of the UV radiation from the sun, preventing it from reaching the Earth's surface.
- If the ozone layer were to disappear, the amount of UV radiation reaching the Earth's surface would increase significantly, causing widespread damage to plants, animals, and humans.
- Human activities, such as the use of chlorofluorocarbons (CFCs) in refrigerants and aerosol sprays, have been responsible for the depletion of the ozone layer in recent decades.
- International efforts, such as the Montreal Protocol, have been successful in reducing the production and use of CFCs, and the ozone layer is slowly recovering.
