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).
The ozone layer protects us from UV radiation. The gases in our atmosphere is what protects us from meteors, due to frictional forces as a meteor slams into our atmosphere at high speeds. Certain chemicals we put into the air can deplete the ozone, such as CFC's.
