Who cares? Science Diplomacy and the global commons

When most of us think of 'the world', it is easy to consider it a jigsaw puzzle of discrete nation-states, each lord over their own jealously-guarded territories. Yet most of the globe we live on falls outside of these neat jurisdictional boundaries - these are the earth's shared natural resources such as the oceans, the atmosphere, the Antarctic, and outer space. These are the global commons, and they are the jurisdiction of all, and none.
