Dissolve?
Well that explains the lack of mess.
There is a theory that we are, that all life that's ever been on this planet is planet is a terraforming mechanism.
First we just had to shit, to temper the atmosphere.
And that's still why most of us here.
To keep shitting.
That's your value.
You shit, therefore you are.
Then we build roads, and cities.
And when our roads and cities finally meet their standards, and air pollution has reached their norm, that will autoterminate us from respiratory disease, they move into their cosy preferbished planet.
