5. THINK IT THROUGH You are a USDA official and must decide whether to allow the planting of a new
modified strain of cabbage that is tolerant to a best-sell-
ing herbicide and has twice the vitamin content of regu-
lar cabbage. What questions would you ask of scientists
before deciding whether to approve the new crop? What
scientific data would you want to see? Would you also
consult nonscientists or consider ethical, economic, and
social factors?

For the strategies below, decide whether they are best described as demand-side solutions or supply-side solutions to meeting human needs for fresh water. remember that a demand-side solution reduces demand for fresh water, whereas a supply-side solution increases the supply of fresh water. (a) damming a river to create a reservoir (b) desalinating seawater (c) a nation invading a neighboring country to access their rivers (d) raising water prices for consumers and businesses (e) providing tax breaks for companies that use less water (f) replacing inefficient irrigation with more-efficient drip irrigation to grow crops (g) requiring low-flow showerheads in all new homes
