Human Modifications to the Environment 2.5abc

Human beings are constantly modifying the environment to meet their needs. When we modify something we change it. Some of the ways we modify our environment is by building, digging, cutting, or changing the land. Humans change the environment by clearing land, building roads, farming, and drilling for oil.

When we clear land, trees and forest are cut down. The lumber is taken to be used for building materials. Animals are either killed in the process or forced to relocate. The empty land is then used for farming, roads, or buildings homes and buildings.
