This can't possibly be a serious thread. If silica sand was "normally" harmful to humans, just about every beach in the entire world would be shut down.
Is silica potentially dangerous? YES
Can you get silicosis from silica sand? YES
If you eat enough of it can it be harmful? YES
The real danger in silica sand is usually from sand blasting or other rock crushing operations. When sandblasting, much care is taken especially in OSHA rules. The danger to the sandblasting personal is not just the sand as is, it is because the sand becomes powdered into a fine dust. Not only that, but the surface being blasted contains various forms of rust and the paint contaminants. The personal are normally well protected by suits and breathing apparatus. They also work in screened in areas to stop the drifting of the dust into the environment.
These dangers are mainly for people that are in constant exposure to sand blasting operations and are not protected. this problem can reach out into cement and concrete workers that are constantly exposed to it. It is nothing like asbestos exposure. If you dont like the sand lying around just cut open tha bag and spead it in your garden or around trees. I promise you, you will not die.
