Clean, fresh water is essential to life on Earth. Water pollution is a global threat to this vital resource. Acid rain is a prime example of how activities in one area can have a serious effect on conditions of a global scale. Acid rain primarily results from the transformation of industrial pollutants such as sulphur dioxide (SO2) and nitrogen oxides into other compounds such as sulphuric acid (H2SO4), and nitric acid (HNO3). This transformation occurs as these pollutants are transported in the atmosphere over distances of hundreds to thousands of kilometers. For example, sulfur dioxide emissions from industrial processes and the burning of fossil fuels have resulted in extensive acid rain and accompanying water pollution problems in southeastern Canada and the northeastern US. These emissions have global implications: more than half of the acid deposition in eastern Canada originates from emissions in the United States. Even slight changes in the pH of lakes and rivers can cause the loss of fish and invertebrates which are important links in the food chain. Acid rain is also responsible for extensive loss of forest cover in that region.

  • @2rich4ubud usually around 5.6, but in the eastern US it can be averaged around 4.03 sometimes

  • whats the ph of rain water?

  • Regulating sulfur dioxide emissions which produces acid rain is, unfortunately, being overlooked.

    In order to address this serious problem, I wish it were a separate issue apart from man-made climate change (GHG), which has become so controversial.

    Also overlooked by regulatory agencies is the negative effect of shooting laser beams into the ionosphere. Could this be what's accelerating the natural cycle of planetary climate change that none of the scientists are allowed to address? See HAARP
