1. Decide whether the event shifts the supply or demand curve (or perhaps both).\ 2. Decide in which direction the curve shifts. 3. Use the siupply-and-demand diagram to see how the shift changes the equilibrium price and quantity.
Man-made causes of depletion of ozone layer: The main cause for the depletion of ozone is determined as excessive release of chlorine and bromine from man-made compounds such as chlorofluorocarbons (CFCs).
Even minor problems of ozone depletion can have major effects. Every time even a small amount of the ozone layer is lost, more ultraviolet light from the sun can reach the Earth. Every time 1% of the ozone layer is depleted, 2% more UV-B is able to reach the surface of the planet.UV-B increase is one of the most harmful consequences of ozone depletion because it can cause skin cancer. The increased cancer levels caused by exposure to this ultraviolet light could be enormous.he risk of ozone depletion was that too much ultraviolet radiation would reach the earth's surface, resulting in high levels of skin cancer. Industrial processes can result in slightly acidic rain as a result of high levels of sulphur dioxide and nitrogen oxide pollution.
