Environmental Science
“Nature has the power to
refresh and renew”- Helen Keller
Several environmental
issues such as pollution, global warming, ozone layer depletion, acid rain,
deforestation, land slide, drought and desertification have gained major focus
across the world. Environmental science provides holistic knowledge about
natural processes, effects of human intervention and solutions to overcome such
environmental issues. Thus, it is defined as the study of patterns, processes
in the natural world and their modifications by human activities. Elements of
nature continuously undergo changes and transformations. They are recycled over
and over again on earth and make themselves always available on earth. In the
same way, all living organisms react with their environment and develop certain
morphological, anatomical, physiological and reproductive features to withstand
particular conditions. This lesson deals with biogeochemical cycles,
adaptations by the plants and animals, water conservation and recycling of
water.
