An overview of future global environmental concerns and a strategy for teaching action skills to students are presented. Information from "The Global 2000 Report" and quotes from 11 different people provide a variety of perspectives on future problems and solutions concerning world food and hunger, economic growth, population, water, air, natural resources, and ecological balance. A Proactive Action Model, consisting of three elements (perception, thought pattern, and action), is proposed as a method of helping students develop the critical thinking and decision-making skills necessary to deal with global environmental problems. Three basic timeline personality types are identified (yesterdays, todays, and tomorrows), and ideal futurists are considered to represent a combination of all three types. A sample unit on global pollution for grades 6-12 demonstrates how the Proactive Action Model works. (DC)
