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).
Air pollution leads to ozone pollution and acid rain. CFC compounds, used in aerosol sprays prior to 1995, destroy the ozone layer. Ozone pollution can cause damage to human respiratory tracts. Ozone can damage the vascular system of plants.
