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 low birth-rate, environmentally focused policy.

This simple radiation balance model shows the greenhouse effect that an atmosphere can have in warming a planet.  By trapping some of the radiation emitted by the planet the atmosphere can cause the surface to become warmer than it otherwise would be.

"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
