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 low birth-rate, environmentally focused policy.
The World3 model is a 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.
The principal creators of the model were Donella Meadows, Dennis Meadows, and Jørgen Randers.The model consists of several interacting parts. Each of these dealt with a different system of the model.
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 what Limit to growth discribed is below:
Scenario2: Initial Nonrenewable Resources 1000000000000->2000000000000
Scenario3: Scenario2+Desired Resource Usage Rate 4.8e9->1.2e9
Scenario4: Scenario3+Desired PP Index 1.2->0.4
