In 2011 the United Nations Environment Programme reported that, if nothing changes, humanity<br />

will dem<strong>and</strong> 140 billion tons <strong>of</strong> minerals, ores, fossil fuels <strong>and</strong> biomass every year by 2050. This<br />

is three times our current rate <strong>of</strong> resource consumption, <strong>and</strong> far beyond what the Earth can<br />

supply. 34<br />

Climate change<br />

Climate change refers to general shifts in climate, including temperature, precipitation, winds,<br />

<strong>and</strong> other factors. Global warming is <strong>of</strong>ten misunderstood to imply that the world will warm<br />

uniformly. In fact, an increase in average global temperature will also cause the circulation <strong>of</strong> the<br />

atmosphere to change, resulting in some areas <strong>of</strong> the world warming more, others less. 35<br />
