Over the years at 60 Minutes, we've been in more than a few tunnels. We explored Mexican drug lord El Chapo's subterranean escape routes, burrowed through a Roman villa buried by Mt. Vesuvius and traveled the depths of the New York City subway. But nothing prepared us for a place called Moab Khotsong, a South African gold mine that extends nearly two miles beneath the surface. In their pursuit of gold, South Africans have dug the deepest holes on earth. The country was the world's top gold producer for decades. Now the gold is running out, just as these ultra-deep mines have attracted a new breed of miner—on a very different quest. We went along for the adventure. In the early morning light, tall mine shafts loom over the Vaal River basin two hours southwest of Johannesburg. This once was a booming gold field, now most mines lie abandoned but Moab Khotsong is bustling. Long before the sun rises, thousands of miners start lining up for the triple-deck elevator called "the cage." … [Read more...] about What lies at the bottom of one of the deepest holes ever dug by man?

(CNN)The hole in the Earth's ozone layer is expected to fully heal within 50 years, climate change experts predict in a new UN report. A fragile shield of gas around the planet, the ozone layer protects animal and plant life from the powerful ultraviolet (UV) rays of the sun. When the ozone layer is weakened, more UV rays can get through, making humans more prone to skin cancer, cataracts and other diseases. Scientists discovered huge damage to the layer in the 1980s and identified chlorofluorocarbons, or CFCs, as the main culprit. CFCs used to be common in refrigerators, aerosol cans and dry-cleaning chemicals, but they were banned globally under the Montreal Protocol of 1987. The decline in CFCs in our atmosphere as a result of those measures now mean the ozone layer is expected to have fully recovered sometime in the 2060s, according to the report by the UN Environment Programme, World Meteorological Organization, European Commission and other bodies.
