Wars are not Grown Naturally
Wars are not grown naturally like plants but engineered by some greedy minds and war mongers to steal the diverse types of resources, both in kind and value. In short, war is a milking cow for ill minds and greedy bellies.
The planet was green, the plants and the animal kingdom grew in a symbiotic environment. The human being was dragged into greed. They made groups, borders, weapons, and armies to satisfy their greed (of a diverse kind). The weaker and poor communities and the people are the sufferers.
