I don't think the world is the problem really guys! I think we are the problem itself!!! We are the destroyers, and the healers, we are the killers and resuscitators. So, as along as we have the power to be good and bad, I think we should change ourselves NOT the world. The world has been here for billions of years and it WAS doing just fine till we came with our greed and lust..... Let's change and the world will change as a result.
You can try to change the world by leading by example.. Treat others like you want to be treated.. do the things that you would want your own children to do. I haven't had much luck with forcing other people to change. if I did I would be out of a job!
