The World3 Model: Classic World Simulation
Scott Fortmann-Roe
The World3 model is a detailed simulation of human population growth from 1900 into the future. It includes many environmental and demographic factors.
Use the sliders to experiment with the initial amount of non-renewable resources to see how these affect the simulation. Does increasing the amount of non-renewable resources (which could occur through the development of better exploration technologies) improve our future? Also, experiment with the start date of a more environmentally focused policy.

The Inescapable Dynamic of Economic Growth
Hanns-Jürgen Hodann
Modern industrial civilisation has created massive interdependencies which define it and without which it could not function. We all depend on industrial farming to produce the food we eat, we depend on gasoline being available at the gas station, on the availability of electricity and even on the bread supplied by the local baker. Naturally, we tend to support the institutions that supply the amenities and goods to which we have become accustomed: if we get our food from the local supermarket, it is likely that we would be opposed to it’s closure. This means that the economic system that relies on continuous growth enjoys implicit societal support and that nothing short of environmental disaster or a shortage of essential raw materials will impede it’s growing indefinitely. It is not hard to work out the consequences of this situation!

Does increasing the amount of non-renewable resources (which could occur through the development of better exploration technologies) improve our future? Also, experiment with the start date of a more environmentally focused policy.
"The World3 model is a system dynamics model for computer simulation of interactions between population, industrial growth, food production and limits in the ecosystems of the earth.
It was originally produced and used by a Club of Rome study that produced the model and the book The Limits to Growth (1972).
The creators of the model were Dennis Meadows, project manager, and a team of 16 researchers
The main systems are: the food system, dealing with agriculture and food production, the industrial system, the population system, the non-renewable resources system, the pollution system.
Scenario is below
Scenario2: Initial Natural Resource 1T -> 2T
Scenario3: Scenario2 + Persistent Pollution Tech Change Multiplier (-1,0)->(-1, -0.04)
Scenario4: Scenario3 + Yield Tech Change Multiplier (-1,0) -> (-1,0.04)
Scenario5: Scenario4 + Land life time 2100 -> 2002
Scenario6: Scenario5 + Resource Technology Change Multiplier (-1, 0) -> (-1, -0.04)
Scenario7: Scenario2 + Year of continued fertility change 2100 -> 2002, Time to zero population growth 2100 -> 2002
Scenario8: Scenario7 + Desired annual industrial per capita output 400 -> 350, Year of Industrial Equilibrium 2100 -> 2002
Scenario9: Scenario8 + scenario6
Scenario10: Scenario9 + Policy adoption year 2002 -> 1982
