Extracted: How the Quest for Mineral Wealth is Plundering the Planet, by Ugo Bardi, Chelsea Green Publishers, 2014

The Club of Rome shot to fame with publication of The Limits to Growth in 1972. This report on the future of mankind not only triggered a hot debate, but degenerated in all-out smear campaign. By the time its critics had had their say, the public perception of the report was that it offered nothing more than a series of wrongheaded predictions made by a group of deluded scientists. So much so, subsequent reports by this global think tank have not merited much attention.

Extracted is the latest report from this elite club. Had The Limits to Growth attained popularity, the title of this report could easily have been The Limits to Extraction. Digging out the history of mining, from prehistoric times to the modern age, the report suggests that mankind has extracted most of the cheap mineral resources available while plundering of the earth’s ecosystems and displacing millions of people. Mining is one of the largest global industries, but the gradual depletion of low-cost minerals, including fossil fuels, is fast becoming a major limitation to economic growth. Since high-grade ores are extracted first, it will become much more expensive to produce mineral commodities in future. Given the growing demand for precious metals and rare earths, however, a resource war is likely to emerge among countries that hold quasi-monopolies over certain mineral deposits.

The political economy of mining makes it an important growth engine for most countries. China has 97 per cent of all active rare earths, including exclusive deposits of molybdenum. South Africa holds 82 per cent of global platinum. China leads countries like Chile, Australia and Argentina in global copper output. Tibet has become the new mining focus for China. Under a new regime, India intends to go full throttle into mineral extraction.

Extracted is written by a team of experts, headed by Italian scientist Ugo Bardi. The report says that deposits of many high-grade ores are running low: copper, zinc, nickel, gold, silver and others are expected to reach their productive peak within less than two decades. Not only will this affect our lifestyles, but it may cause agriculture production to decline as well. By the time the world wakes up to the full impact of mining (including oil and gas), the lasting impacts may be impossible to reverse.

The solution, says Bardi, is to replace costly minerals with cheaper ones; recycle as much as possible, and generate energy through renewable energy sources such as sun, wind and water. He and his colleagues believe that mining machines and drilling rigs will disappear without a corresponding decline in the demand for minerals.
