Sulfur- 25 lbs – CQ Concepts

The burning of coal and/or petroleum by industry and power plants creates massive amounts of sulfur dioxide (SO2) which reacts with atmospheric water and oxygen to produce sulfuric acid (H2SO4). This sulfuric acid is a component of acid rain, which lowers the pH of soil and freshwater bodies, resulting in substantial damage to the natural environment and chemical weathering of statues and structures.

Are there CO2 emissions from natural gas? | HowStuffWorks

Natural gas is formed over thousands of years as decaying plants and animals are trapped under layers of rock. Due to extreme pressure and heat, this organic matter begins to slowly break down. Gradually, the energy stored in the organic matter is turned into carbon. The result is one of three energy sources -- coal, petroleum or natural gas. Natural gas -- historically considered the cleanest of the three -- mainly .
