ISSUES OF THE ENVIORNMENT ECOSYSTEM&ITS DESTRUCTION -; ECOSYSTEM IS THE SYSTEM CONSISTING OF LIVING &NON LIVING ORGANISMS. IT IS A PART OF BIOSPHERE. IT IS FEATURED BY ENERGY &MATTER FLOWING BETWEEN THE DIFFERENT ELEMENTS THAT COMPOSE IT.ECOSYSTEM MAY BE NATURAL OR ARTIFICIAL .

AND IS A MAJOR CAUSE OF ENVIORNMENTAL PROBLEMS.NEED FOR MORE LAND IS CAUSING DEFORESTATION. 2.INDUSTRIALISATION- SETTING UP MORE INDUSTRIES &INDUSTRIAL UNITS IS LEADING TO CLEARING OF FOREST LAND & AGRICULTURAL FERTILE LAND.BIOLOGICAL DIVERSITIES IS LOST FOREVER. IT ALSO RESULTS IN POLLUTION IN VARIOUS WAYS.

IT LEADS TO; DISRUPTION OF SURFACE & GROUNDWATER CIRCULATION,RESHAPING OF TOPOGRAPHY,SOIL EROSION,LANDSLIDES,DEGRADATION OF LAND. EXCESSIVE CONSUMPTION OF RESOURCES-: RESOURCES INCLUDE AIR,WATER,SOIL,FUELS,ETC RENEWABLE RESOURCES- ARE REGULARLY REPLINISHED THROUGH NATURAL PROCESS.THEY LAST VERY LONG.EG WATER,WIND,SUNLIGHT ETC.
