"A Breath of Air" details the work of University of Southern California scientists on the health effects of air pollution on children, and also the community perspective on air pollution in the Los Angeles area.

greenhouse gas molecules like CO2 and how they trap heat in our
Forests are also one of our best defenses against global warming,
absorbing vast amounts of carbon pollution out of the air. But power
companies are increasingly proposing to burn whole trees for energy.
Trees are not a "carbon neutral" fuel source.
