SAN FRANCISCO, Mar 09 (IPS) – I am about 200 feet down a rickety old mine shaft, in the Ashanti gold mining region of Ghana. It is stiflingly hot and darker than a moonless night. I can only feel the touch of sweaty bodies passing in the darkness and hear the reverberating sound of miners coughing and breaking rocks. The lack of oxygen and dust make it hard to breathe. I have no idea how deep this shaft goes – hundreds of feet? More? If there is a Hell this must be what it feels like.
