Explain three ways that human activity negatively affects Earth's natural resources.

Using chemical fertilizers, insecticides and herbicides to increase production actually pollutes the air, soil and water with toxic chemicals. Fertilizer run-offs cause toxic algal blooms that kill aquatic animals.

Removing trees and other plants to increase areas of cultivation causes habitat loss and threatens the survival of numerous species of animals and plants. Large scale farming of animals increases their susceptibility to diseases such as Mad-cow disease and avian flu, for example. Waste generated in the farms and meat processing plants can affect the water quality in the area.
