Humanitys demand on the planet has more than doubled over the past 45 years as a result of population growth and increasing individual consumption. In 1961 almost all countries in the world had more than enough capacity to meet their own demand; by 2005 the situation had changed radically with many countries able to meet their needs only by importing resources from other nations. A move toward sustainable living by increasing public awareness and adoption of recycling, and renewable energies emerged. The development of renewable sources of energy in the 1970s and \'80s, primarily in wind turbines and photovoltaics and increased use of hydroelectricity, presented some of the first sustainable alternatives to fossil fuel and nuclear energy generation, the first large-scale solar and wind power plants appearing during the 1980s and \'90s. Also at this time many local and state governments in developed countries began to implement small-scale sustainability policies.', '1987']}}]}]
