Another fine story. I am sad to find myself agreeing with the concept that homo sapiens need to die out eventually, but the reality is that the world will continue to exist after man is extinct. The condition of the Earth depends on the timing of the extinction event. The Earth might be dead on the surface, but it will still exist. I always wondered in the various Star Trek iterations if there were any euthanasia movements that use the transporter system in a similar fashion as you did to send people out to the universe. What a good way to go.
