Around the globe, scientists are racing to solve a series of mysteries. Unsettling transformations are sweeping across the planet, and clue by clue, investigators around the world are assembling a new picture of Earth, discovering ways that seemingly disparate events are connected. Crumbling houses in New Orleans are linked to voracious creatures from southern China. Vanishing forests in Yellowstone are linked to the disappearance of wolves. An asthma epidemic in the Caribbean is linked to dust storms in Africa. Scientists suspect we have entered a time of global change swifter than any human being has ever witnessed. Where are we headed? What can we do to alter this course of events? National Geographic's Strange Days on Planet Earth, premiering in Spring 2005 on PBS, explores these questions. Drawing upon research being generated by a new discipline, Earth System Science (ESS), the series aims to create an innovative type of environmental awareness. By revealing a cause and effect relationship between what we as humans do to the Earth and what that in turn does to our environment and ecosystems, the series creates a new sense of environmental urgency. Award-winning actor, writer and director Edward Norton (Primal Fear, American History X, Italian Job) hosts the series. A dedicated environmental activist, Norton has a special interest in providing solar energy to low income families. Each of the four one-hour episodes is constructed as a high-tech detective story, with the fate of the planet at stake.
