• Plants and animals thrive in the new environment and pollution decreases.

• New animals species form and plants produce more oxygen.

• The shopping mall reduces the amount of pollution in the area.

• Habitat is altered, plants and animals destroyed, and pollution increases.

Human activities constantly affect the ecosystems that are in close proximity with human settlements. The graph shows the population of oak trees around the city of Greenville, South Carolina. If all other factors remain the same, what will most likely happen to the oak tree population over the next five years if the human population continues to grow?

• If all other factors remain the same, what will most likely happen to the oak tree population over the next five years if the human population continues to grow?

• The oak population will increase as people become more aware of environmental issues.

• The oak population will stay the same as people plant new trees to replace trees that are cut.

• The oak population will decrease as people build more homes.
