This is a sad commentary on modern man.
Thousands of years ago, people could not only make tools that made survival more likely but they were able to communicate concepts and methods from one to another without written language (or YouTube videos).
Many people today would die from exposure, thirst or starvation if the modern supply system were to shut down for a few days. Not to mention their inability to change a flat tire on an automobile.
We've come so far. :-(
take away the toys and the riots and looting starts...
They'll fight over the last case of bottled water.
BTW, I've flagged several people recently who have blatantly plagiarized your posts, this one and one of the others about stone tools.
They're easy to spot, they post the exact same images.
