I would like to warn people that I am quite a pessimist, and if you do not wish to see my views, please discern this post.
World peace will not happen before human inhabitants cease to exist. So I can not really disprove that statement. Either way, someone will end up unhappy, it is all just cultures, if one were to change people by force and just live off of the land like everyone did thousands of years, people would be happy, the thing is human beings are brilliant. They want to advance, there is beauty in science, but it also disgusts me. People constantly trying to make THEIR lives better whilst others don't even have the life they do. People know about the terror in other places in the world, think about it and then move on with their lives, that is not happiness, that is ignorance. Life is tough, and nobody can honestly beleive that the world will become a better place before people figure out how to make bombs that level off continents. It is corrupted order, it is want, it is fulfillment of purpose, there is no purpose yet everyone seeks something. They all want to know what will become of them; they all want a future. Just constant knowledge is apparently more important than lives, knowledge is power. Not living people, or animals, the importance in everyone's mind is research, knowledge and development.
