Scientists discovered, and have confirmed, that sulfur dioxide (SO2) and nitrogen oxides (NOx) are the primary causes of acid rain. In the US, About 2/3 of all SO2 and 1/4 of all NOx comes from electric power generation that relies on burning fossil fuels like coal.cid rain is a broad term used to describe several ways that acids fall out of the atmosphere. A more precise term is acid deposition, which has two parts: wet and dry.
The soil in the temperate deciduous forest is very rich and fertile and needs to be protected instead of poisoned. The biggest contributor to acid rain is car exhaust. Some ways that we could help prevent soil pollution is carpool as much as you can to decrease the amount of car exhaust that we produce. Another way in the future is to find an alternative for fossil fuels so were not polluting the earth, soil, and air as much.
