How does agriculture affect the environment?

Environment has a direct influence on existence and sustainability of agriculture as it depends upon the use of natural resources . Undoubtedly, agriculture has a greater environmental impact on Earth than any other single human activity. Conventional agricultural farming practices will not provide the food and fibre needed by burgeoning population in the future. In general, the question arises, can we develop and adopt the agriculture farming practices that can produce the food needed to feed an increasing population and simultaneously sustain our environment on long term basis. Under most systems of agricultural production at this time, it is not a question of if, but rather when, virtually all of the natural habitat on the planet will become degraded to the point that it is no longer productive and then abandoned for future generations to find ways to rehabilitate and repair. Farmers are beginning to invent, adapt and adopt a wide range of new technologies and approaches but most of them are not environment friendly. Hence, this paper reviews the linkage between environment and agriculture and the resultant impact of agriculture on environment.
