The communications revolution has given millions of people both a wider and more detailed understanding of the world. Because of technology, ordinary citizens enjoy access to information that formerly was available only to elites and nation-states. One consequence of this change is that citizens have become acutely conscious of environmental destruction, entrenched poverty, health catastrophes, human rights abuses, failing education systems, and escalating violence. Another consequence is that people possess powerful communication tools to coordinate efforts to attack those problems.
