Anthropology discussion

What are the causes of the water crisis world wide according to the movie “Blue Gold” and the assigned articles in your textbook and on BBLearn? What do you think are tenable public policies to correct this crisis? What effect do dams have on the supply of healthy fresh water?

I just need about 200 words to discuss and answer these questions.
