Here we go again and need these questions answered "ASAP". I really appreciate all the work and research you do. Thanks a Bunch !!! #1 Returning Customer.  Questions as follows: 1. Describe the hydrologic cycle. Make sure you fully explain the (3) main components of the cycle. 2. What is the main industrial use of water? 3. Differentiate between point and nonpoint sources of water pollution. Please give examples of each. 4. What is thermal pollution? How can it be controlled? 5. What is photochemical smog? What causes it? 6. What is acid rain? List three probable detrimental consequences of acid rain. 7. Why do you think air pollution is so much worse in developing countries than in developed countries? What should developed countries do about this, if anything? 8. What common indoor pollutant are you exposed to? What can you do to limit exposure? I would like you to find an Internet site that discusses indoor air pollution. Air pollution often gets neglected in discussions of pollutants in general - but humans are spending more and more times indoors as their jobs become more demanding. Please provide a summary of information you find on the website and IDENTIFY THE SOURCE OF INFORMATION at the beginning or end of your answer.

"I recently discovered a leak under my toilet in my bathroom resulting in floor damage and mould. After a relative helped by removing and replacing the flooring, water sealed plywood was put down and greenboard and an epoxy seal, I was told if there were any future moisture problems greenboard would let the homeowner know of water damage due to greenboard fails so my tiles would drop 1/4 if there were any leaks, if not it would last for some years, not forever, but enough. but I am told otherwise now that this is not acceptable, this room is a low traffic, one person, low moisture bathroom.  Am I safe with the way this was installed. Please help."
