First deal with your own tears; tomorrow do something about acid rain. You may have heard about acid rain depending on where you live. Acid rain now refers to rainfall or atmospheric moisture that has been combined with substances and gases that have caused the moisture to become more acidic than normal. Acidic precipitation can be generated by both natural (volcanoes) and man-made activity, such as automobile exhaust and power generation. When power plants and businesses burn fossil fuels (coal and oil), sulfur is released into the air, where it reacts with oxygen to produce sulfur dioxide (SO2). Nitrogen oxides are formed in the air as a result of automobile exhaust. Airborne sulfuric acid (H2SO4) and nitric acid (HNO3) can be produced from these gases and dissolved in water vapor in the air. Although acid rain emissions originate in cities, they are frequently transported hundreds of kilometers across the atmosphere by winds to rural areas. As a result, acid rain that originates in cities can destroy forests and lakes in the countryside.
