Few people will argue with the assertion that many of the conflicts that are going on in the world today are (at the core) related to resource sharing. The question does arise though: as to why the sharing of resources tends to be a major cause of conflicts – because many of the conflicts that are currently ongoing, and many of the past conflicts, are all related to the sharing of resources.
As it turns out, the main reason as to why the sharing of resources tends to be a major cause of conflicts is in the fact that the resources are, by nature, limited. Against that background, some individuals, or groups of individuals, are unable to get satisfied with the shares of resources they get and they decide to fight for what they feel is rightfully theirs: hence the various resource conflicts.
Perhaps we humans can learn about resource sharing from our computers: in which applications tend to share the limited computing resources very well and (in most cases) without getting into conflicts. That is how one is able to, say, seek Logmein remote support from a website such as www.logmein123.com whilst at the same time running a Linux Word Processing application. This happens without having the respective processes run into conflict over access to (the limited) computing resources.
