> The only way to prevent it is to raise the standard of living in these African countries so that no one would consider taking a mining job there in their current form.

South african miners in 2012 tried to raise their standard of living from 500usd to 1500usd per month; 47 people died[0] and I don't think any real change took place; sad.
