What Would You Do?

What is the one thing you would most like to change about the world? PLEASE Comment!

As cliche as it sounds, peace. I want people to quit killing each other because we are different. Can't we just agree to disagree, do we have to kill each other? If we were all exactly the same, well someone would change because they wanted power or money or got tired of agreeing and wanted to create a problem. I don't understand how any God could possibly condone killing. Peace.
