Acid rain can best be reduced by?

Question

(1).increasing the use of high-sulfur coal
(2).controlling pollutants at the source
(3).reducing the cost of petroleum
(4).eliminating all use of nuclear energy

Answer 1

All rain for eons has been slightly acidic; its because of traces of CO2 dissolved in the rainwater; thus making it acidic slightly.
Nothing has change except the Liberals are trying to get mega-grant money out of the productive people for studies on this issue. Funny how the Liberals always find ways to be "leeches on the productive!"

Answer 2

For purposes of your test question, #2 is the correct answer. But, there's way more to acid rain than that. As one other answerer correctly observed, rain has always been slightly acid because of dissolved CO2. True, sulfur pollution may lead to more acidity but humans are not the only source of sulfuric pollutants. Volcanoes produce vast quantities of sulfuric pollutants. One of the more interesting observations I have ever seen (sorry I can't give you a reference) about factors that used to mitigate acid rain in the eastern U.S. was that in bygone days of higher wind erosion in the Great Plains, the wind picked up vast quantities of fine soil particles. These soil particles on the Great Plains are frequently or usually of a basic pH in nature. As these basic particles were carried eastward on prevailing winds, they became mixed with the acid precipitation and tended to neuralize the acidity. When wind erosion became less of a problem, the eastern U.S. rainfall became more acid once again. The problem with all of this is that we have only been around to measure the pH of rain for a very short time in history. My contention is that we still don't know what normal is or what the complete normal range of acidity can be over time and over cyclical weather events. Something the environmentalists never tell you is that for crop soils, since we have been trying to reduce sulfuric pollutants, there have been more incidences of soils deficient in sulfur, which in turns leads to the need to add sulfur fertilizers. Hope I'm not rambling. When studying environmental issues, please keep an open mind. Don't just swallow everything without checking it out and trying to verify the truth or error in your own mind. Environmental issues are very complex.

Answer 3

Controlling pollutants at the source. Like chimney scrubbers.
