Two greenhouse gases that cause ozone depletion?
Question: Two greenhouse gases that cause ozone depletion?
Two greenhouse gases that cause ozone depletion are chlorofluorocarbons (CFCs) and halons. These are synthetic chemicals that were formerly used in refrigerants, aerosols, solvents, and fire extinguishers. They release chlorine and bromine atoms in the stratosphere, which react with and destroy the ozone molecules. One chlorine atom can destroy up to 100,000 ozone molecules, and one bromine atom can destroy even more. Ozone depletion leads to more harmful ultraviolet radiation reaching the Earth's surface, causing various environmental and health problems.
CFCs and halons are regulated by the Montreal Protocol, an international treaty that aims to protect the ozone layer by phasing out the production and consumption of ozone-depleting substances. However, some of these substances still persist in the atmosphere for decades, and their substitutes may also have some negative impacts on the ozone layer and the climate. Therefore, it is important to continue monitoring and reducing the emissions of these gases and finding safer alternatives.
