Climate change »
Climate change
Climate change☜Because of the delays in the climate system, the greenhouse gases that are up there now are going to determine the climate for about 15-20 years ahead – even whatever happens in terms of the reduction of greenhouse gases, or indeed their expansion.☜9FDEF6

Population Growth »
Population Growth
Population Growth☜We are going to reach a further billion people by 2025. We also know the distribution of that billion — about 500 million in Africa 500, about 500 million in Asia. Changes in fertility will not affect it much.☜9FDEF6
●
Urbanization »
Urbanization
Urbanization☜Unless development patterns change, by 2030 humanity’s urban footprint will occupy an additional 1.5 million square kilometres - comparable to the combined territories of France, Germany and Spain—with the equivalent of a city of 1 million needed weekly across the next 38 years.☜9FDEF6
