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).
SAVING THE OZONE: Part three in our series exploring on the Montreal Protocol on Substances that Deplete the Ozone Layer â dubbed âthe worldâs most successful environmental agreementâ â explains why we need an ozone layer. The ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (UVR) from the sun, protecting life on Earth from its potentially harmful effects. When the sky is clear, there is an inverse relationship between stratospheric ozone and solar UVR measured at the Earthâs surface.
