Working our differences with communication is civilized. Discussing how to share resources in a sustainable way that also protects them for the future is civilized. Trade among nations and groups can help protect peace because it is just good business then to protect your trading partners. Protecting resources from becoming contaminated with pollutants is also just good business. If a resource is used up or becomes polluted then it can no longer benefit anyone.
"If you want peace you don't talk to your friends, you talk to your enemies." - Desmond Tutu
Communication and reaching mutual understanding can led the way to peace.
