Global Change: Witnessing the Impacts

Presented by some of the foremost experts on global change in North America, with footage from the islands of the Arctic to the Salton Sea in California, this series explains the complex issue of global change in a way that is both clear and compelling. Looking at population growth, atmospheric and bio-diversity change, and environmental quality, this program shows evidence of what damage has been done, along with scientific projections of what is likely to occur if consumption of the earth's resources is not reduced.åÊThis program looks at atmospheric and biodiversity change and the global warming phenomenon. We investigate the effects of pollution on various ecosystems and why the Arctic has been affected by pollution from Southeast Asia, helping us understand how our local activities may be affecting people on the other side of the world for years to come.
