Environmental Science students are studying the impacts of water delivery systems on the environment and human civilization. They have received a worksheet that contains questions based upon a video, shown on class, called "Mulholland's Dream", which is based, in part, on a famous book by late environmentalist Marc Reisner, called "Cadillac Desert".
For students who were not in class when the video was shown, or who wish to see the entire (unedited) program again, I have provided the following links:
In addition to completing the worksheet, Environmental Science students must research and answer the following questions:
1. What is the estimated current population of Los Angeles County? Make sure you tell me the source of your estimate!
2. Water has many uses, but let’s just focus on drinking water. Find a source that estimates the amount of water in liters needed by a single human being, each day. Tell me the source, and provide the estimate.
3. Using your research from questions 1 and 2, estimate the total amount of drinking water in liters required annually by the population of Los Angeles County. SHOW YOUR WORK!
4. Based on your answer to question 3, do you think that Los Angeles County will have to find new sources of water in the future? Give a reason to support your claim.
5. Los Angeles relies on aqueducts and canals to obtain most of its water. What are the sources of water here in Fresno County?
