Do we really need all the regulatory programs at the federal and state levels of government?
Do they really work to improve the quality of our air and water? Are they worth their cost in terms of regulatory burden and costs of compliance? In short, yes! To some extent, our regulatory programs are a trial and error affair. We can’t always know the ultimate effectiveness of a new program nor its ultimate costs. We can’t always predict the economic benefits of new regulations either since they invariably lead to innovation and generate new inventions and jobs.
The US has been monitoring the quality of our air and water for decades, so we can track the effectiveness of our programs. The U.S. Environmental Protection Agency (EPA) is making the most recent data available. Air pollution impacts public health, the environment, and the Earth’s climate, and understanding these impacts are important priorities for the agency.
EPA regulatory actions and voluntary efforts have led to cleaner cars, industries and consumer products, that in turn have contributed to improvements in the nation’s air. They have also led to developments of new pollution control systems for power plants and other major sources such as Selective Catalytic Reduction, a technology that removes Nitrogen Oxides from emissions by converting it to Nitrogen and water.
Since 1990, nationwide air quality has improved significantly for the six common air pollutants: ground-level ozone, particle pollution, lead, nitrogen dioxide, carbon monoxide, and sulfur dioxide. Emissions of toxic air pollutants, such as benzene, have declined about 40 percent nationwide between 1990 and 2005.
These reductions are helping to improve public health by decreasing the number of emergency room visits, respiratory illnesses, and premature deaths. Positive impacts can also be seen in the environment, with regional haze decreasing.
Despite this progress, about 127 million Americans live in counties violating at least one of the national air quality standards. The agency has taken recent actions to tighten air quality standards to help ensure improvements in air quality for everyone.
EPA’s most recent evaluation of air pollution, Our Nation’s Air, Status and Trends Through 2008, presents trends in air quality measurements, analyzes national emissions from key industrial sectors and takes a look at the relationship between air quality and climate change.

It’s great that EPA is finding many ways to improve air pollution in America. Due to this people aren’t being as affected as much as they were before when air pollution was a major issue. Our environment is becoming more and more healthier each year thanks to EPA and other organizations that care about saving our people from sickness. Now if we could do something to help other countries with major issues like China?
