"I think", ??
A significant jar to the earth will pretty much finish it off.
We have with nuclear power plants made sure of this, tipping the scales against mans survival.
If you watch the ring of fire and other major events around the planet the frequency is growing ,at an interesting level every day.
Some say the sun is causing it , some blame HARP , some blame global warming,some blame CO2 emissions , and host of other things.
Most of which we can do nothing about preventing.
One's best course might be to move, but where there is less of a threat.
Where can that be ?
I had often thought that the far north and building a biosphere would be sufficient.
Those with big money are already doing that.
But it's costly and few if any are truly self sufficient as a completely stand alone operation. Life is still dependent on the sun like it or not.
Artificial light does not last forever.
Even if you had the technology for making your own lighting the materials may not be redly available.
A lot of specialized handling goes into that operation.
Gathering hard copy on "how to" ,I believe is as important as long term survival foods and gardening.
I go through a lot of ink and paper just from this site ,as well as others ,and roughly several hundred technical books, and catalogs, gathered over at least 50 years.
Machinery hand books and motor manuals s well as how to libraries and instructional manuals even Fords manual for build a business for auto repair, Model A soup to nuts.
Some writings are fairly recent and some date back to the late 1800s.
If for some reason, in spite of all our best efforts to preserve electronics fails , the knowledge for making these things should not be lost, as it has in the past.
If you leave it to some one else to do this, it doesn't get done.
Though I may not be around by the time these things become valuable ,at least they are preserved until that time.
