Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. They use up resources like trees to make many things from paper to money. By that they use up a lot of trees and led to deforestation in that area. They use up all the fossil fuels for work to gain more money. The use of these has left a negative impact on the environment by using up everything and not replenishing it.
