PRESENTATION OUTLINE
Acid precipitation is precipitation such as rain, sleet, or snow that contains a high concentration of acids. When fossil fuels are burned, they release oxides of sulfur and nitrogen. When the oxides combine with water in the atmosphere, they form sulfuric acid and nitric acid, which fall as acid precipitation.

How to prevent
Basically if we were to stop burning all this fossil fuels it would help us very much

How Acid Precipitation Affects Soils and Plants
Plant communities have adapted over long periods of time to the acidity of the soil in which they grow. Acid precipitation can cause a drop in the pH of soil and water. This increase in the concentration of acid is called acidification. Acidification changes the balance of a soil’s chemistry in several ways.

Aquatic animals
Aquatic animals are adapted to live in an environment with a particular pH range. If acid precipitation falls on a lake and changes the water’s pH, acid can kill aquatic plants, fish, and other aquatic animals. The change in pH is not the only thing that kills fish. Acid precipitation causes aluminum to leach out of the soil surrounding a lake.

Acid and humans
Acid precipitation can affect humans in a variety of ways. Toxic metals such as aluminum and mercury can be released into the environment when soil acidity increases. These toxic metals can find their way into crops, water, and fish. The toxins then poison the human body.
