Integration of environmental education and second language instruction is discussed, with two purposes: to describe educators' efforts to protect the planet's deteriorating environment, and to explore what destructive attitudes and actions that have led to environmental devastation have their counterparts in language education methods. The intended result is to heighten students' environmental awareness, knowledge, appreciation, and protective efforts through learner-centered instructional approaches, including learner-generated materials, cooperative learning, encouragement of creativity, integration of subject areas, and involvement with the community. The paper has three main sections. First, environment education is described and placed in the context of a global approach to education. Controversies in environmental protection are discussed briefly here. Second, the psychological and linguistics roots of a learner-centered approach to education are contrasted with those of a teacher-centered approach, and learner-centered classroom techniques are described. The third section contains environmental activities for second language learners using a learner-centered approach, including songs, data-based exercises, problems in decision-making, and making resolutions about protecting the environment.
