Plot Synopsis

The elements of fire, water, and air formed the Earth over billions of years, but in a short period of time, humans have severely transformed it all. Over the millennia, our impact has become so significant, it has started to change the planet's ecosystems. So, how do we move forward in this altered world we've created, and what we can do to change both our behavior and our environment? AGE OF HUMANS travels the globe to examine humankind's influence on Earth -- from the dawn of civilization to today -- and the steps we're taking to create a positive future. The series opener, "Earth," reveals how we have spoiled Earth on a scale like never before in the history of humankind and how, throughout the world, alternatives are being explored to save the planet... and ourselves.
