"In fact, scientists are only now beginning to understand the vast range of services-natural, social, psychological, ecological and economic - that forests perform: the water they clean and retain; the climate patterns they regulate; the medicine they contain; the food they supply; the soil they enrich; the carbon they entrap; the oxygen they emit: the species of flora and fauna they conserve; and the peoples whose very physical existence depends on them". These are the words of Wangari Mathai who won the Nobel peace prize in 2004.

Rachel Carson, an American biologist, writer and conservationist, with her Sea trilogy explored the whole of ocean life from the shores to depth.  In the late 1950s, she turned her attention to conservation and came out with ‘Silent Spring’ (1962) that dealt with the problems caused by synthetic pesticides and the ways and means to solve these problems. Actually this book brought environmental concerns to the American public and that led to the creation of the United States Environmental Protection Agency (EPA) in 1970s. Thus, ‘Silent Spring’ Sparked the global grass roots environmental movement in 1962 by proclaiming as humans are dependent on their living environment, the environment’s protection is inevitable.
