After doing some research on different opinion sites, I have come to a conclusion that MANY people believe that if there was to ever be a World War 3, one of its main causes will be oil. My opinion on this topic is that I agree with what these people are saying. Going back a couple posts ago, I talked about oil being a commodity, and because it is one, which means that there will be a time where nations will be desperate because there is not as much oil left. Oil is a very powerful tool in our lives today, and every country needs it to keep our life styles running, so if everyone NEEDS this rare oil, everyone will be fighting for it. That’s my personal opinion on that; you can leave your opinion in the comments below!
