And many scientists beleive, that the impact of consumption has reached a level which is at the limit of environmental sustainability - or already above. Extrapolating to the end of the century, production will have increased by a factor of about 40. The population growth factor for the century will be about 4. This means that consumption per capita will have grown by a factor 10. Increased consumption per capita, in particular in the industrialized countries, has had a more heavy effect than population growth, but both count.
Global population continues to oncrease strongly.
It grows with 80 to 90 millions a year. That of the industrial countries is already practically stable. The big question is now, what will happen to global consumption up to that time, which is not far off. In the following calculation it is assumed, that the consumption in the industrial countries will double. That would be a very low growth over the considered period of 50 to 60 years compared to the past.
