Often times there are a number of parameters in a model you want to set to specific values and run the model to demonstrate a particular behavior. When there are several variables involved remembering the setup is often difficult and takes time. And can you demonstrate the behavior when you're not there? Developing scenarios with Button scripts is a quick way to overcome these difficulties.

Changes to V19: calculation of energy investments set on base and additional materials, not materials as a fraction of a total

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.
