The global consumption of key raw materials is rising fast. Over the 20-year period ending in 1994, the world population increased by 40% – in that same period, the world consumption of cement increased by 77%, and plastics by just under 200%… Among raw materials used for construction, only crude steel registered a growth rate that was significantly lower (only 3% from 1974 to 1994) than the rate of population increase. (University of Minnesota, 1999).
