Regarding my theme, I learned more about the destructiveness of war and why us humans do it. I added some psychology in my paper to support my point. Apparently, deep inside of our brains we have a piece called "The Reptilian Brain". This part of the brain regulates the bare necessities to sustain life like breathing, sexual desires and our basic fight or flight instincts. We inherited three harmful components of the reptilian brain which are: Tribalism, short-term thinking, and wishful thinking. What impacts humanity's decisions the most regarding war is tribalism. All roots of conflict in history has been caused by tribalism. One group declared that they are better than one another which results in the competition among humans which could spiral into conflict then war.
