The world has never been more closely and intricately connected. Our behavior (51) the environment we all share, and we are tied into a global economy and global communication system. (52) choosing to buy one garment rather than another we help determine whether someone on the other side of the world retains or (53) their job; emissions from one part of the world contribute to a hole in the ozone layer somewhere else; we can (54) with others anywhere via satellites, the Internet and the mobile phone. This interdependency, (55) "connexity", is the defining characteristic of the world today.

In politics, the sovereignty of nations remains a (58) concern.
