  2. Tuesday September 3, 2019 E.Q. for Tuesday: How have some countries overcome their lack of water? Warm-up: What are the benefits of building dams?

  3. ANSWERS E.Q. Answer for Tuesday: Because water is a natural resource in such short supply many SWA countries have resorted to using irrigation to farm and raise farm animals. In addition there has been a lot of work done to learn how to take salt and minerals out of sea water(desalination). This process is very expensive and requires complex technology. Warm-up Answer: Dams control flooding, provide lakes for irrigation and produce hydroelectric power (electricity).

  4. Wednesday September 4, 2019 E.Q. for Wednesday: What do farmers use along with irrigation to produce bountiful harvests? Warm-up: Overuse of chemical fertilizers can lead to what environmental problems?

  5. ANSWERS E.Q. Answer for Wednesday: Many farmers have begun to use chemical fertilizers to boost production and feed hungry consumers. Warm-up Answer: Constant planting and overuse of chemical fertilizers have led to water and soil pollution.

  6. Thursday September 5, 2019 E.Q. for Thursday: Why are many farmers in SWA considered subsistence farmers? Warm-up Answer: Overuse of chemical fertilizers can lead to what problems?

  7. ANSWERS E.Q. Answer for Thursday: By definition many farmers in SWA are only able to grow small amouns of crops, just enough to take care of their immediate needs Warm-up Answer: Overuse of chemical fertilizers leads to contaminated water supplies and soil pollution.

  8. Friday September 6, 2019 E.Q. for Friday: How does hydroelectri9c power generate electricity? Warm-up Answer: Water is a critical Natural Resource for what two benefits?

  9. ANSWERS E.Q. Answer for Friday: Fast moving rivers turn electric generators producing electricity. Warm-up Answer: Water is a crucial resource both as a source of life and as a route for trade.
