Q1:Should the United States allow Mexico to have water from the Rio Grande and Colorado River, both of which originate in the United States and flow into Mexico? Should the United States be held responsible for water pollution that occurs within its boundaries but impacts water users in Mexico?

Q2: Perhaps 98-99% of all species that have ever existed on our planet are extinct. Nearly all went extinct long before humans occupied the landscape. Why should we be concerned about the extinction of organisms today?

Q3:A Pacific Northwest Indigenous Group has been permitted to hunt an endangered whale species in order to preserve its traditional culture and uphold its treaty rights. Now there is fear that other countries will hunt the whales. Do you think Indigenous rights should be upheld, or should they also fall under the limitations imposed by national legislation?
