The Causes, History and Effects of Acid Rain

In the past few decades, precipitation across North America and Europe has become increasingly more acidic having an immense effect on the ecosystem. Any rain below the natural pH level is considered acid rain. Acid rain primarily occurs when extraneous sulfur dioxide is released into the atmosphere and mixes with the air; nitric oxide, typically from burning of fossil fuels, is a secondary cause. First being discovered in the mid-20th century, the phenomena has had detrimental effects on lakes, rivers, soils, plants, and the overall environments that cannot neutralize water. This chapter thoroughly covers the history, causes, and environmental effects of acid rain.
