Abstract Our earth planet have a large area occupied by the different things like soil, ocean and space. Oearth planet contains biotic and abiotic factors . Abiotic factors like edaphic facto ,climatic factor ie soil, light,temperature etc.Biotic factors are producers , consumers and decomposers. Producers are all green plants, . Consumers are herbivores, carnivores and omnivores animals. Decomposers are all microorganisms and Along with the farming, man has domesticated a variety of animals like cows, buffaloes, sheep, goat for his benefits. Because of these animals, the problem of overgrazing. has resulted in the destruction of forests, grasslands, disappearance of more palatable plants species etc. In such localities, some unpalatable, annuals, weeds, shrubs start to grow and turn the whole area into man-made desert. Use of mechanical devices for farming, fertilizers, pesticides, hybrid varieties of crops resulted into green revolutions. It did increase crop yields two times or three times in many tropical countries. However, this green revolution has given rise to certain ecological problems. Excessive use of water for irrigation has changed fertile land into saline and marshy land which ultimately pesticides also resulted into soil, water and air pollution.
