The use of the environment has increased in order to satisfy the needs of men. Therefore, human negligence and collective actions for economic gains have put the environment at a disadvantage.Many of the natural ecosystems have been interfered. This has been through encroachment on forest reserves, degradation of wetlands, uncontrollable expansion of agricultural land leading to soil erosion and soil exhaustion, overgrazing and burning of grasslands leading to bear soils that are susceptible to erosion agents.
