Global environmental change is interwoven with complex human activities. These activities which are transforming the global environment have many faces. Ozone depletion, deforestation, acid deposition and increased atmospheric concentration of gases that trap and warm the global climate. We, the humans use energy and emit pollutants in our quest for food, shelter, clothing's and a host of other products for the world's fast growing population. We burn fuels that emits heat trapping gases which build up the atmosphere. ...........
Tropical forests are cleared for agricultural, grazing and logging. Materials are drawn from the earth to run the engines of world economy and we treat the atmosphere, land and water as receptacles for the wastages generated from consumption of energy. Just similar to the function of the glass panels of a green house built in the cold countries,the gases keep some of the earth's heat from escaping through the atmosphere................
