#1 The metal aluminum was rare for most of history, until it was discovered in 1825 by Hans Christian Oersted and Frederick Wohler. It was then used in the Hall-Héroult process, which liberated aluminum from bauxite.
#2 Scarcity is often contextual. For example, imagine a giant orange tree packed with fruit. If I pluck all the oranges from the lower branches, I am out of accessible fruit. But once someone invents a piece of technology called a ladder, I’ve suddenly got new reach.
#3 The OPL initiative, created by BioRegional Development and the World Wildlife Fund, is a set of ten core principles that stretch from preserving indigenous cultures to the development of cradle-to-cradle sustainable materials.
#4 Scarcity has been an issue since life first emerged on this planet, but its contemporary form is what many call the scarcity model. It was in 1968 that the Club of Rome, a group of international thinkers, gathered together to discuss the problems of short-term thinking in a long-term world.
