Human Impact on Earth: Cause and Effect

Earth's environments are constantly changing and have
been since Earth formed. However, Earth has changed drastically since the dawn
of the earliest human relatives. In the last twenty years or so, scientists have
found that human activity has put three-quarters of Earth's land surface under
pressure. This set explores how humans have impacted a number of environments
and how these places might look if humans didn't exist there. Suggested
conservation efforts show readers that hope isn't lost for these parts of Earth,
and that they can help make these environments healthy once again.
