The Hubbert Curve does not just apply to oil. The Great Beyond: Shortages of scarce natural resources coming, warn chemists Shortages of scarce natural resources coming, warn chemists - March 27, 2011 Leading chemists from around the world have warned that scarce natural resources, such as phosphate minerals mined for fertilisers, are dwindling at an alarming rate and shortages could hit within a generation. (See Natures coverage of the phosphate crisis here and here.) Five scientific societies, including the Chinese Chemical Society, the German Chemical Society, and the UKs Royal Society of Chemistry, warn in a report today that falling supplies of these essential elements are a potentially more pressing concern than the decreasing supply of oil. Little public awareness exists about the uncertain supplies of these key materials that we face today, and the potential future shortages. Secure, adequate supplies of these materials are essential for production of food, medicines, computers, and hundreds of other products, adds Nancy Jackson, president of the American Chemical Society, which also contributed to the report.
