The human race possesses a few traits that are beneficial to the species. It also has a few weaknesses. But let's focus on our ability to be compassionate towards one another. We exist in families. Units of mothers father's daughters and sons. We have love. We care for one another. Our entire planet is composed of these units. This alone allows for the possibility of unification to ensure best survival possible for each and every single individual. Another trait is our ability to be efficient.  We can efficiently care for every single individual on the planet in the least amount of effort giving everyone equal luxury. Of course these traits require that we overlook one of our greater weaknesses our ability to not use our brains.
