The U.S. Environmental Protection Agency's 12-minute documentary, Science to Protect the Air We Breathe, tells the history of air pollution in the United States and the important discoveries by EPA researchers and collaborators that provided the information needed to reduce and control air pollution. EPA research continues to address new challenges to air quality, including mixtures from difference sources and climate change.

Air is free of charge! But Time will come we will need to buy clean air per volume in a container just to live if we don't act to protect it todaY.
