Could We Survive Without Violence?

Could the life on earth exist with no violence? Most would say something like "sure we can" or "of course," well I say no. War is absolutely everywhere, look around, every argument, fight, debate and so on is only just a small form of violence. The entire cycle of life is made of violence, one animal kills another, then another, then another. If there weren't violence we would be confused, for we could not learn off our own mistakes. We wouldn't know how to love. Life as we know it could not exist. If you live in the rainforest hunting is survival, but isn't it violence? You and the animal are both fighting and someone or something will die. In the end I ask the same question, could we survive without violence?
