Prevention methods to stop fatalities from comets ,asteriods and other disasters.

As Biden said on Fox and I have thought too. We can prevent many disaster fatalities by building multi disaster proof facilities underground and also develop cities underground. We can start an underground culture by making facilities like schools big business have underground. For underground make them earthquake,ocean,levy, ocean covering proof, gas, bacteria, hurricane, asteriod proof and blast proof,fireproof,cold proof, nuclear proof,space proof,sun proof, radiation proof, hunger proof and suffocation proof, We can solve these problems multiple ways. Later on we can make depository place for all animals,insects, plants,seeds, robots,rocks, medical, culture, religion and information. If we ever had to start over with a small population, we would rebuild the world with robots,cell phones,Internet,emergency services and defense. We can also build shields eventually that will stop other things.
