The world is shrinking. The ice caps are melting. A sneeze, thousands of kilometres away, starts a health pandemic, and technology enables us to intimately view not only earthqueakes and tsunamis but human rights violations around the world. This reality calls for an understanding of sustainability, diversity, and social justice. A global citizen is aware of the wider world, respects diversity, is outraged by injustice, participates in community from the local to global level, and feels compelled to act to make the world a more humane and sustainable place. Global citizenship will help students gain personal understanding of themselves as citizens of the world and apply it in their own lives.
