Deforestation(Read more in detail) means to clear the forest land by cutting the trees and shrubs and converting it into a commercial or a residential land. This is because most of the water used by us is found in the ground. We all rely on groundwater in some way, and groundwater relies on us to protect it. Furthermore, when some aquifers are mined, the surface soil area tends to sink, making it impossible for the aquifer to be refilled (Pimentel et al. MEANING OF ENVIRONMENTAL EDUCATION.
