or the past three centuries, the effects of humans on the global environment have escalated. Because of these anthropogenic emissions of carbon dioxide, global climate may depart significantly from natural behaviour for many millennia to come. It seems appropriate to assign the term ‘Anthropocene’ to the present, in many ways human-dominated, geological epoch, supplementing the Holocene — the warm period of the past 10–12 millennia. The
Anthropocene could be said to have started in the latter part of the eighteenth century, when analyses of air trapped in polar ice showed the beginning of growing global concentrations of carbon dioxide and methane. This date also happens to coincide with James Watt’s design of the steam engine in 1784.
Mankind’s growing influence on the environment was recognized as long ago as
1873, when the Italian geologist Antonio
Stoppani spoke about a “new telluric force which in power and universality may be compared to the greater forces of earth,”

Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth's stratosphere, and a much larger springtime decrease in stratospheric ozone over Earth's polar regions. The latter phenomenon is referred to as the ozone hole. In addition to these well-known stratospheric phenomena, there are also springtime polar tropospheric ozone depletion events. The details of polar ozone hole formation differ…
Literature exclusively studies man with respect to race, gender, class and psychology. The study of man has not been a complete process. Man is more than a social animal as he faces more challenges in his diurnal life living in a digitalized society. Very few are the works that claim the subject related to man’s survival and existence in the technologically advanced society. Literature has taken many drifts in the changing world. Now, it has taken a new turn towards the environmental studies since…
