PART-V: Wild species face extinction threat

GREEN GOLD IN DANGER: PART-IV
Man-animal conflict a major challenge
Ajmer Alam WaniJAMMU, AUG 21: Though the tropical forests cover only 7 % of the earth’s land surface, they contain more than half of all living species. Estimates of the number of living species on earth vary from five million to 80 million of which only 1.4 million have been described. Wild species and the genetics variations within them make substantial contributions to the development of agriculture, medicine and industry. According to an estimate, between 1990 and 2020, species extinction caused primarily by deforestation may eliminate between 5 and 15 per cent of the world’s species, a potential loss of 15,000 to 50,000 species a year. The forest area is considerably decreasing day by day. The satellite imageries study of National Remote Sensing Agency (NRSA) revealed that forest area in 1972-75 was 55.5 mha only, which reduced to just 46.3 mha in 1980-82, indicating an average rate of depletion of forest area of a…
