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).
Ozone occurs in two layers of the atmosphere. The layer closest to the Earth's surface is the troposphere. Here, ground-level or bad ozone is an air pollutant that is harmful to breathe and it damages crops, trees and other vegetation.It is a main ingredient of urban smog.The troposphere generally extends to a level about 6 miles up, where it meets the second layer, the stratosphere.The stratosphere or good ozone layer extends upward from about 6 to 30 miles and protects life on Earth from the sun's harmful ultraviolet (UV) rays.t is a main ingredient of urban smog.
