From what I heard and read in the newspaper is that acid rain had an environment impact. It damages forest and soil, pants and fish. Recently due to the damage in Japan nuclear plant, news has been around and they advise people to stay indoor and avoid the rain. I believe it have negative effect to human health too.

Acid rain can be harmful especially if there is a high content of it in the rain. Almost everything can be affected. The first thing that comes to mind is corrosion. This affects not only metallic structures, but also other buildings. Too much acid falling into the soil can make it infertile. Living plants can also be directly affected. Health wise some people are easily affected by it. The most common affliction is a headache if the head is unprotected, and exposed to the first few minutes of an acid rain. Longer exposure to the rainfall, depending on factors like the loclity and actual acid content in the rain, would likely negates the effect because the acid gets washed away. By the way the emissions come from sources like factories, coal based power stations, and most motorised vehicles. Regulations were introduced to reduce the emission level.

"Acid rain is a rain or any other form of precipitation that is unusually acidic, i.e. elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the release of sulfur dioxide into the atmosphere with positive results. Nitrogen oxides can also be produced naturally by lightning strikes and sulfur dioxide is produced by volcanic eruptions."-http://en.wikipedia.org/wiki/Acid_rain You only really need to worry about this if there has be some kind of devastation like volcanoes and explosions. It is caused when it rains after one of these because then the chemicals mix in with the rain and gets brought down to earth.
