How is Acid Rain Formed? Burning of fossil fuels releases nitrates and sulfates into the air. Nitrates and sulfates mix with water vapor on air and form nitric acid and sulfuric acid (acid rain). Acid rain causes damage to plants, changes pH in soil and water systems (acidification), and chemically erodes statues, bridges and buildings.

Herbicides & Pesticides We spray herbicides and pesticides without knowing the possible long term consequences. (Examples PCB & DDT)

PCB & DDT Can build up in the environment causing Biological Magnification. Chemicals accumulate in top predators leading to lethal effects. Video – Human Population and Strained Resources (play the first two minutes).

Acid rain tends to fall only in Arctic regions Acid rain pollutes useable water in lakes, rivers, and oceans and could potentially poison the plants or animals consuming it. The organisms in Earth’s biosphere are rarely affected by acid rain and can filter out the unwanted chemicals. C 21
