HUMAN INFLUENCES ON THE ENVIRONMENT
Because humans are often poorly adapted to their environment (they do not have warm fur coats, sharp claws, night vision, or the ability to photosynthesize their own food), they have learned to change their environment to survive.

Technological advances have changed the face of the Earth as well as the composition of the atmosphere and the hydrosphere.
