Indeed the world is taking a serious information as the emission of chlorofluorocarbons, halons, and other destructive gases are causing ozone holes to appear in the stratospheric ozone layer. Various anthropogenic activities such as emissions of CFCS, HCFS and other organo-halones lead to the depletion of ozone. Which is responsible for adverse effects on plants, human and environment with increased number of bronical disease human. The mutation caused by UV rays result in variation in morphogenic traits of plants with ultimately decreases oup productivity. UV radiation is required in optimum intensity for both plants and animals.
