The Task A local citizens' group has hired you to investigate acid rain. You will take on the role of a Chemist,Ecologist, Health Scientist, and Economist and examine the issue from that perspective. Your task is to create a report detailing the problems caused by acid rain and recommend ways that these problems can be alleviated. Use the questions appearing under each role to assist you in your research. While you are researching, look for solutions to the problems caused by acid rain. The final section of your report, you will also be responsible for drawing up a series of recommendations on how to combat this serious issue. CHEMIST What is acid rain? What chemicals make rain acidic, and how does it happen? Where do these chemicals come from? How do we measure the acidity of rain and what is pH? What is the pH of normal rain, and at what level does the pH become dangerous? What can power stations and industry do to reduce acid rain? What can we do to reduce acid rain?
