Go outside and take a deep breath. The air is cleaner today than in the 47 years since the first Earth Day celebration in 1970, so why do so many Americans think the environment is getting worse?
Air pollutant concentrations and emissions have plummeted since 1970. The combined emissions of six criteria pollutants regulated monitored by the Environmental Protection Agency (EPA) fell 71 percent in that time.

A recent report published by the Association of Air Pollution Control Agencies (AAPCA) found “Americans are more likely to view the environment as getting worse and express that they worry a great deal about air pollution and the environment in general.”
“Despite tremendous strides in all measures of air quality since 2000, trends in national and international surveys show that there has been little movement in American public perception about air quality,” AAPCA reported.
Based on these worries, Americans regularly support federal and state regulations on emissions from power plants, industrial facilities and vehicles.
“With media more likely to report bad news combined with often apocalyptic framing by advocates and limited understanding of technical air quality information, it is no wonder that the public is often confused about air quality in their city, county, state, and nation,” AAPCA reported.
