Document Summary
Objective: think about the best way to construct a model to describe an environmental system, using models to conduct experiments. Mathematical models: mathematical models use equations to represent connections in a system, in computer simulation models the calculations are turned over to the computer. Examples of complex systems: co2 in the atmosphere could increase for the remainder of the century. Even after we decrease the amount of co2 released: ddt would increase in ocean fish even after many decades trying to reduce the amount released. Model building process: build a mathematical model to capture key interrelationships in a system, conduct experiments with computer model to cultivate ability to manage the simulated system, develop clear and explicit assumptions, document all steps *important* A computer model was used to simulate: resource production and food supply needed to sustain a growing system, the generation of persistent pollutants increases and remain in the environment over many decades.
