Imagine if the world didn't follow the trade/barter system. People just helped people with no demanding of getting something in return. Now of course some people would abuse this policy, but that would be a longer time ago. I believe that humanity is becoming more aware, more concsious of each other. We are starting to realize that we live on this earth, we must protect our earth or some globally drastic could happen and we won't live anymore. Of course that is a motivating thought process, love the earth or die, but none the less the mass of the population took it upon themselves to help oneself, to help their fellow man, and to help the planet that they live on, all for no money or anything.
