Multiple Choice

What will most likely be the result as humans move into new areas, forests are clear cut and housing developments are built?

• Global temperatures will decrease because trees are removed.

• Many organisms will lose their homes because their habitats have been destroyed.

• Better sanitation in the area will reduce the amount of pollution.
