When thought of acid rain, some people may think of green, burning acid falling from the sky, destroying everything in sight. This may be a bit ridiculous and hard to believe, but as absurd as it sound, it is not far from the truth. Acid deposition has long been a subject of debate because of the widespread environ-mental damage it is responsible for. As one of the major results of air pollution, acid rain can corrode metal and limestone structures, leach important minerals, decreased fertility of soils, and lower pH in lakes and ponds. For those who fear "the end of the world," acid rain may pose a threat as it creates a bad environment for both animal and human. And for those who care about our planet, maybe it is about time we stop destroying it and give something back to Mother Earth.

There are numerous causes of acid precipitation, several of these are insignificant and accumulate into severe cases.

However, there are also some sources that are menacing by itself, sources such as industrial emissions. In some cases, acid rain is caused when industrial fumes mix with moisture in the atmosphere. Acids are then carried in clouds for long distances before they are deposited through rain, which indicates that forests and lakes far away from factories may be damaged by acid rain. Another significant cause of acid rain is automobile exhaust. Research has shown that although industrial emission makes up for most causes, sulfur dioxide from oil and coal combustion

and nitrogen oxides produced from automobile engines have greatly intensified the problem. Electric power plants are also to blame for this issue. Recent study has shown that power plants are accountable for the release of more than 20 million tons of sulfur Per. 3 dioxide each year.
