Of note is McLuhan's insistence that the world becoming a global village should lead to more global responsibility. Technology has created an interconnected world, and with that should come concern for global events and occurrences outside one's own community. Postman builds on this concept with the idea of teaching the narrative of 'Spaceship Earth' where students are taught the importance of everyone taking care of planet earth as a fragile system of diversity both biological and cultural; however, the original person to coin the term 'Spaceship Earth' was futurists Buckminster Fuller, who once said, "I've often heard people say: 'I wonder what it would feel like to board a spaceship,' and the answer is very simple. What does it feel like? That's all we have experienced. We're all astronauts on a little spaceship called earth."
