I remember the dialog from Agent Smith in matrix movie he stated that humans goto a region and colonize it until every recourse is consumed and then they move to a different place. and the same pattern is followed by the viruses around us. So are we a species whose behavior is similar like virus or it makes viruses a supreme living/non living organisms.
I have always agreed with that statement. I used to think that globally everyone could get behind the idea that we need to change our thought patterns and consumption trends, but I don't see it anymore. What is far more likely is that like many Sci-Fi series show is that we are going to spread to other planets or natural satellites to colonize and consume.
I also see another factor coming into play that distinguishes us from a virus. Thanks once again to our continued over consumption of goods, this time antibiotics, we are creating the planets cure for us in the form antibiotic resistant infections and illnesses.
I guess you could also argue that we are some type of super virus, as I don't know of a virus that will kill/consume itself (same species/race) as a found resource in a new host.
