Our terrestrial experience with toxic remediation, realized recycling efficiency, natural resource management, and other sustainable civil engineering impacts should universally apply to our future space suburbia.An Expensive Cup of CoffeeConsider the complex and expensive process of lifting materials into orbit and keeping them balanced against the grasp of earth's gravitational field. Just moving a pint of water into high earth orbit is estimated to cost over $15,000 US and takes months of multidisciplinary engineering. Currently there is no reason to believe similar factors will not apply for any inhabitable body in space for many years to come. From this standpoint alone, once hypothetical materials transportation to these large bodies has been accomplished it would make sense to keep them there, under control and under no circumstance wasted or discarded. This was a primary impetus for recently lifting a high tech urine
