The use of the technology of the human species began with the conversion of natural resources into simple tools. The prehistoric discovery of how to control fire and the subsequent Neolithic Revolution increased the available food sources and the invention of the wheel helped human beings to travel and control their environment. Historical events, such as print, telephone and the Internet, have reduced physical barriers to communication and allowed human beings to interact freely on a global scale. The steady progress of military technology has brought weapons of ever-increasing destructive power, from clubs to nuclear weapons.
