To help assess the consequences of food policies, the world's food system is being assembled into models. These models should help planners evaluate the impact of food-related policies and will try to account for the interactions of all food-related supply and demand factors. (BT)

Discusses computer simulation approach of Limits to Growth, in which interactions of five variables (population, pollution, resources, food per capita, and industrial output per capita) indicate status of the world. Reviews other books that predict future of the world. (CS)

In this simulation, secondary students explore the potentials for cooperation and conflict that have existed in relation to control of the seas. Through playing roles of decision makers of various nations, students learn about issues and positions involved in exploiting the wealth of th sea, including minerals, oil, and fish. (RM)

This is the student guide in a set of five computer-oriented environmental/energy education units. Contents of this guide are: (1) Introduction to the unit; (2) The "EARTH" program; (3) Exercises; and (4) Sources of information on the energy crisis. This guide supplements a simulation which allows students to analyze different aspects of…

The article describes a study of the effects of experience with an energy-environment simulator on the attitudes of its users. The study concludes that tools like the energy simulator appear to provide an important way to help educators take a leadership role in solving energy problems. (RE)

This simulation helps students in grades four to eight see their planet as one environment with limited resources shared by all. Students learn that the earth is a large system comprised of small systems, that systems are interdependent and often have irreplaceable parts, and that resources are not equally divided among countries. (RM)

This paper describes the International Futures (IFs) computer assisted simulation game for use with undergraduates. Written in Standard Fortran IV, the model currently runs on mainframe or mini computers, but has not been adapted for micros. It has been successfully installed on Harris, Burroughs, Telefunken, CDC, Univac, IBM, and Prime machines.…

The issue of Intercom promotes an awareness of the world as a system that poses new possibilities and obligations for educators as well as policy makers. The first part includes interviews with and excerpts from the works of Denis Meadows, joint author of Limits to Growth; Mihajlo Mesarovic, co-author of Mankind at the Turning Point; Robert…
