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).
Explain the role of the ozone layer in sustaining life on Earth. The ozone layer helps regulate the Earth's temperature by absorbing a large percentage of the UV radiation entering the atmosphere. This protects living organisms from exposure to large amounts of UV radiation, maintains livable climates, and regulates the amount of harmful ground-level ozone. Compare the health and environmental risks associated with ground-level ozone to the health and environmental risks associated with ozone layer depletion.
