How has technology changed the world?
It has changed our world in many ways: - computers - phones - medicine - MOST IMPORTANTLY....ALL MEDICAL TOOLS, TREATMENTS, AND PROCEDURES! I can't tell you how thankful our world should be because of technology and how it has shaped the medical world! :) - Vaccines - email - online chat-rooms - ALL OF SCIENCE! AND ALL OF SCIENTIFIC TOOLS, AND LAB EXPERIMENTS! - facebook - telephone calling - TV - HD - AND ANYTHING ELSE THAT WAS NOT INVENTED IN THE FIFTIES! LOL!
