How much is left?

The global middle class is expected to increase by three billion people in the coming decades. China and India, for example, will double their income per capita 10 times as fast for 200 times as many residents than England did during the Industrial Revolution. So, the demand for resources will only continue to grow at a time in which finding and extracting new resources will be growing increasingly more difficult. The direct consequence is that resource prices will fluctuate significantly. In the long term, certain crucial, raw resources will probably become scarce and expensive. And we haven’t even covered the environmental impact of the extraction. This makes everything about our traditionally linear lifestyle unsustainable.
