Since the beginning of real environmental awareness, we have shown that by innovative application of technology we can significantly reduce the amount of pollutants introduced into our biosphere while maintaining our society and economy.
According to the US Environmental Protection Agency's Ten-Year Air Quality and
Emissions Trends report, there have been significant reductions in all 6 criteria
pollutants and reductions are expected to continue. The pollution reductions between
1986 and 1995 were:
Carbon Monoxide (CO)
|
down 37%
|
|
Lead
|
down 78%
|
|
Nitrogen Dioxide (NO2)
|
down 14%
|
|
Ozone
|
down 6%
|
|
Particulate Matter (PM-10)
|
down 22%
|
|
Sulfur Dioxide
|
down 37%
|
These reductions are in addition to huge reductions accomplished in prior decades. Our water, land, and air, especially around large industrial centers, are far cleaner now than they were in the late 1960's. Reducing the amounts of greenhouse gases introduced to the atmosphere is the next challenge in our efforts to curb pollution and the deleterious effects people have on their environment.
Greenhouse gases (GHG's) are those compounds identified as potentially causing warming or other effects on the earth's atmosphere. GHG's are emitted from many natural and man-made processes. Some researchers are predicting that the amount of GHG's being introduced into the atmosphere by anthropogenic processes are causing unnatural changes in our global climate. Volumetrically, most processes release more carbon dioxide than any other GHG and it has the potential for causing the largest amount of climate change. Thus, carbon sequestration is the focus of much research and debate.
