True, but that needs explanation. Platinum has been used in catalytic converters since the mid 1970's. More than 80 % of the worlds platinum supply is found in Africa. You tell me what happened in Africa to account for platinum's astronomical rise.
Platinum has been a strategic material vital to the nation’s defense for a long time now. The two sources of platinum being south Africa and Russia have presented an interesting problem. Another source is outer space, but this source cannot be developed at present due to the 1967 UN Outer Space Treaty. I like to suggest often that the Treaty be repealed now.
