Why is conservation of resources essential? List out three methods of soil conservation


Conservation of resources is essential because some resources like minerals are non renewable and need conservation for future generations. Conservation is a judicious and careful management of resources by man as improper and overuse can deplete them leading to many ecological problems.
Three methods of soil conservation are:
(i) Terrace farming : Cutting of hilly areas into steps to reduce the flow of running water.
(ii) Strip cropping : Growing of crops in long strips.
(iii) Planting of shelter belts : Shrubs and trees are planted along fields to control the force of wind.
