| "Today, for every one of the more than 5.8 billion people on Earth nearly six tons of carbon dioxide are spewed into the air annually. As a result of our activities, the atmospheric concentration of this heat-trapping gas has risen by more than 30 percent." Environmental Defense Fund |
| Urbanisation will increase any projected carbon emissions by more than 25%, particularly in developing regions, also mainly through effects on labour supply. High productivity of developing urban labour, extracted from household surveys, shows that urbanisation increases economic growth, which result in increased emissions. |
By 2050, the world's population will reach 9 billion. This video touches on the demands this will put on our energy resources and innovative solutions to these future energy issues.
