1; helium three, immense value fuel for power plants.
2; see #1
3; one insane microbiologist viewing humans as parasites and a moon colony would be a lost opportunity for the survival of the human species.
What power plants? There are no power plants that use He3 as a fuel. There are no power plants under construction that use He3 as a fuel. There are no power plants planned that use He3 as a fuel. Fusion power is a pipe dream currently. While not a bad concept, no one has come up with a way to make it work except on an explosive basis.
As to #3 this is something that goes on on a daily basis without the insane microbiologist to direct it. Deadly antibiotic resistant bacteria are constantly evolving simply because we treat people with antibiotics, and some people succumb, but so far it hasn't ended the human race. Even AIDS - about as deadly a disease as you can imagine - hasn't made that much of a dent.
