These models and simulations have been tagged “economic-activity”.
The term 'work' has been used in this model in the sense of economic activity to include not only
work done by people but also by machines. The model shows 8 positive
feedback loops that reinforce work and the need to work. From the perspective of physics, civilisation can be described as a MACHANISM FOR USING ENERGY AND DOING WORK.
Work, however, has some unavoidable consequences. The second law of thermodynamics
tells us that any ‘work’ requires the use of energy and that DOING WORK entails
the generation of WASTE HEAT. The laws of physics also tell us that CO2 emissions from burning fossil fuels will cause global warming. These unintended
and unavoidable consequences are highlighted in the model by prominent arrows.
the structure of this system be changed to avoid a foreseeable collapse of civilisation?
