more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger‚ additional ultraviolet rays are allowed to pass through. These rays cause cancer‚ cataracts‚ and lowered immunity to diseases.1 What causes the depletion of the ozone layer? In 1970‚ Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His findings started research on "global biogeochemical

called Ozone Depletion Ozone depletion deals with the steady decline in the concentrations of ozone in the stratosphere due to its faster destruction by chemicals released by man into the environment. Depletion is mainly caused by chlorofluoro carbons (CFCs)‚ halons‚ methyl chloroform and carbon tetrachloride. There substances contain chlorine or‚ bromine which‚ can reach the stratosphere. These elements are capable of catalytically breaking down ozone into oxygen. Ozone depletion can also be caused

Introduction Water‚ although one of the most fundamental human needs‚ is often not readily available for the world’s poor. To address this need‚ many water-supply and distribution technologies have been successfully implemented to provide clean‚ reliable water in close proximity to its end users. Rainwater harvesting is one of these options available for consumers. It has the potential to provide water for a variety of purposes. Rainwater harvesting is one of the most basic forms of water collection

TEXT 1 CASH CROP In agriculture‚ a cash crop is a crop which is grown for profit. The term is used to differentiate from subsistence crops‚ which are those fed to the producer’s own livestock or grown as food for the producer’s family.
