We now have the ability to colonize Outer Space! Warp Drive and Teleportation make this possible. Colonizing will protect against natural disaster and/or Alien attack.
Plans are underway to colonize Mars. But Warp Drive opens up the rest of the Milky Way Galaxy and other Galaxies.
[Note: America has a working Jump Drive. We've had it since 1972! It is easily capable of distant Galaxies. It requires a lot of electricity but no more than a sophisticated satellite.]
