But guns won't help you anyways, shooting the goo does nothing.

If you want to actually survive, you will need food. Cultivating plants is impossible since the anomaly apparently affects them too, so your only option is canned food from underground sources. Once that runs out, your only choice is eating the goo... And while the article says it is not dangerous, there is no way to be sure. You are basically screwed.

The only option that guarantees long-term survival would be uploading your mind into a robot. The Foundation probably has the technology needed for this. Robotic humans could safely roam the surface and prepare an interstellar space mission to find our species a new home in a different solar system. (Well, unless all stars and not just the sun are affected by 001... In this case, we will have to stay robots forever.)
