What is Stigmergy?

[Wallfire]

So far this has been an interesting post. Now I would like to state a fact, this fact is valid for everything we know about the Earth we live on and the universe it belongs to.
For some thing to live something must die.
Anyone who spends time in nature understands this, to live you have to be better that what is trying to kill you and be better than what you are trying to kill.
In your job place you have to "kill" your fellow workers in order to keep your job and survive.
Every cult and religion no matter what they say wants to "kill" the other cults and religions in order to survive, its how everything works. Humans did not invent this, its just how everything works.
Can this be changed ? I dont know. One thing I do know if you dont understand how something works and you try to change you will end up making it worse.
To survive one must belong to a group, the bigger and more powerful the group the better the chance of surviving and moving forward. 
AS wants his group to be the biggest and best, to "kill" the other groups, to make the world better, but is it possible to change the very building block of everything, For some thing to live something must die
