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.
