The aim of this pamphlet is to make secondary school students aware of the interdependence of peoples throughout the world and of their own responsibility to the world at large. The pamphlet is written from a Christian and a socioeconomic perspective. The text is arranged into the following broad areas of continuing world problems: the Third World, population, food, poverty, refugees, race, resources, and "one world." It is recommended that these sections be used with a map or globe, and that they be supported by additional materials from current newspapers, magazines, and television documentaries. Each section is divided into subtopics, which are often presented in question-answer format. Maps and graphs accompany the text, and several sections are followed by assignment suggestions relating to the topic, or by illustrative quotations from the Bible and other sources. A list of organizations where students may obtain additional information and a brief syllabus of suggested readings for both teachers and students are also provided. (Author/MK)
