The biggest hole in the world.


Located in Russia, this hole is actually an open pit diamond mine.

That is pretty scary. Helicopters aren't allowed to fly over it, because of natural suction(?). Wonder what impact it has on the earth and the environment? I thought that was a beam of light coming out of the tunnel, but I guess it is something like a tornado or whilrwind.
And it takes two hours to travel from the bottom to the top. Crazy!

JDH: Isn't that crazy that it produces suction!?
I know in gold mining, mercury is used--a very toxic mineral. Have you ever seen pictures of gold mining in third world countries, where the miners are surrounded with mercury?

How surrounded? Like floating?
Mercury and humans don't mix. Didn't mercury cause mad-hatters disease, from applying mercury to bowler hats?
I'd read somewhere that things (chemicals like VOCs in paint and hazardous materials and such) we were exposed to as children or young adults might not affect us but could affect our children or grandchildren on a genetic level - something called environmental hereditary disease or something like that.
Half the chemicals that have been approved for use on lawns, have not been tested for their affects on humans. If we all lived off well-water we'd all be more mindful and concerned for how we treat our land.

JDH: Yes, I've seen photos of workers waste deep, with mercury floating all around them. I understand that mercury helps attract small gold particles; the mercury is then vaporized leaving the gold particles behind. The term 'flash in a pan' was a term used by miners panning for gold. The 'flash' occurred when the mercury was burned off.
There was a study in Canada, where random subjects had their blood tested for toxic materials/metals. Everyone tested positive to metals higher than the 'acceptable' levels.
Pesticides kill birds, bees, beneficial insects and worms, and eventually turn up in the food chain.
Health Canada is warning people not to have tuna more than twice a month; salmon more than once a week. Then there are the ubiquitous mercury amalgams...

I have a cousin who drives one of those big, big, big dump trucks (such as the one shown in this article) in a copper mine in Arizona. She LOVES it!

Hi qt! What a cool job she must have! I've seen films of those Giant trucks, showing people standing beside a monsterous tire or climbing up a ladder to get to the driver's seat. I imagine it must be unnerving though, driving one along the precipice?
