The world has plenty of potash 610 years worth, which ensures centuries more of fertilizer-making, and 590 years of known iron-ore reserves, according to U.S. Geological Survey estimates.
The expert working group will begin with the perspective that geological resources are an important element of development and that biosphere reserves are much more than just protected areas.
But a joint survey by the state-run Petrobangla corporation and the United States Geological Survey (USGS) suggests that Bangladesh's gas reserves could reach as much as sixty-one trillion cubic feet (tcf).
But by accounting for further development, continual technology advances such as horizontal drilling and supportive prices, the U.S. Geological Survey calculates that 86% of total U.S. proven reserves are additions to original numbers.
Last year, the US Geological Survey estimated the Arctic could be home to 30% of the world's undiscovered natural gas reserves and 13% of its undiscovered oil.
