How do we know if fish are being harvested sustainably?

The system begins to get complex, and realistic, and interesting. System states are usually physical stocks, but they could be nonmaterial ones as well: People care deeply about parameters and fight fierce battles over them. Meadows indicates that in most cases, it is preferable to slow down a positive loop, rather than speeding up a negative one.

It is cheaper and easier to change information flows than it is to change structure. Physical laws such as the second law of thermodynamics are absolute rules, whether we understand them or not or like them or not. There was this subdivision of identical houses, the story goes, except that for some reason the electric meter in some of the houses was installed in the basement and in others it was installed in the front hall, where the residents could see it constantly, going round faster or slower as they used more or less electricity.

Congress and the president spend most ppints their time arguing about the many, many parameters that increase spending and decrease taxing the size or depth of the hole. To adjust the dirtiness of the air we breathe, the government sets parameters called ambient air quality standards.

To demonstrate the power of rules, I like to ask my students to imagine different ones for a college. That goal change will effect several of the above leverage points: If the outflow rate is higher than the inflow, the stock gradually goes down. Those of us who were trained by the great Jay Forrester at MIT have all absorbed one of his favorite stories.

It is not price information but population information that is needed. Especially in environmental development matters, the future is primarily in the hands not of governments, but of people who have babies, drive cars, turn lights on and off, buy stuff, generate garbage.
