The ultimate example of humanity's hubris.

As we see further and more voluminous expansion into space, there is the possibility that at least some of that material can find use.  NASA, for the first time since the early 70's, is starting to renew research on Nuclear Thermal Rockets, in which a radioactive source superheats either a propellant or the exhaust of a traditional chemical reaction, granting about double the efficiency of a typical hydrolox engine.  The spent carbon control rods can be compressed in the center of of a ball of non-radioactive carbon into a diamond which generates electricity, but does not emit any harmful rays.  Radiothermal generators do not necessarily need to use Plutonium anymore since we've been able to engineer a lot of our electronic components to require less power.

I'm not trying to downplay the horrible environmental impact that our collective amateurish handling of radioactive waste materials has had, but if we do see tens of thousands of people working in space within the next thirty years and the explosion in deep space probes that we are heading towards, turning some of that wasted into something useful will be a godsend.
