World DynamicsExamination of the structure of countervailing forces such as population growth, food production, capital investment, natural resources depletion, pollution, etc., at world level when exponential growth rate overburdens the environment - simulates world growth trends by means of a large-scale computer model and shows that a global equilibrium could be achieved if social policies and programmes were chosen taking into account the dynamic characteristics of world social systems.
