Document Summary

Warmer temperature increase the risk of mortality from heat stress. Diseases like malaria, dengue, yellow fever, encephalitis and cholera are likely to spread more. Warmer and humid condition enhance the growth of mould and bacteria can lead to contamination of food and thus food poisoning. A co2 concentration of 550 ppm increases crop yield in some area whereas it may decrease the yield in other areas. A warmer climate reduce flexibility in crop distribution and increase in irrigation demands. Expansion of pest also increase vulnerability of plants. 3: depletion of o3 layer leads to more uv absorption. It leads to increase of temp. , thus global warming: cfcs also cause increase of co2. Depletion of o3 leads to increase of h2o2 in troposphere: this induces acid rain. Effect on human beings a. a) increases incidences of skin cancer a. b)decrease in immunity level makes people prone to infectious diseases: retards physical growth and affects mental development of human beings.
