Global citizenship and cross-border collaboration has never mattered more. Among the 193 nations that make up the United Nations, the island nation of Tuvalu – less than 13,000 people – has the same vote on referendums in the General Assembly as China, which has more than 1 billion people. But China also serves on the UN Security Council and so can veto any proposal. Because of this strange inequity, the UN has been unable to stop ethnically-driven massacres, genocidal persecution of minorities and other smaller conflicts. On the other hand, it is bringing the world together on climate change. 

Exercise: Turn your class into a mini United Nations. Each student will get one vote. But appoint a small number of students to also serve on the Security Council. (You might choose the tallest, biggest students to emphasize the idea of power imbalance.) Have students propose changes that should be made by the school or your class. Then have the students on the Security Council see if they are willing to endorse the idea, with any one student on it given the power to quash the proposal. Then have students discuss the pros and cons of that structure and the power of the veto.
