@Procrustes,
We all like to dream of this utopia, but the fact is, it ain't so.
Our sun will eventually exhaust it's mass, at which point it will go nova expanding in size until, goodbye planet earth.
Human beings are life forms, subject to all the same rules as other life forms.
We aren't the center of the universe after all.
Most of us are so interested in the big picture, and our egos, that we miss the small show. It is a simple matter to make the world a better place, simply be a better person. The world and it's peoples are fine enough, when I quit excusing and justifying my own behaviors.
Kindness, tolerance, patience, forgiveness; especially when I can justify otherwise. We choose to have enemies in this world, and we're always more interested in how joe blow is acting than in our own actions.
