Human behavior is similar to virus due to its capability to explore and think beyond every border to help its survival. If you would check, we are not different from any plant virus or any animal virus, we tend to exhaust our available natural resources for us to survive; we will do anything to sustain life, which is inevitable for species. The difference on viruses is that they have some cure(some will have) or they have some kind of killers to turn down its populations, that would help its host prevent more damaging effects, while humanity do not have any threat(natural killer) that could help decrease its populations, a problem our host is facing right now. That is why I think we can be classify as supreme virus.
