Lesson: Environmental Conference on Sustainability in Action part of CAMEL:Activities
This lesson uses a jigsaw format to introduce students to a wide range of environmental problems and how local communities have dealt with them successfully. It uses an EcoTipping Points perspective to illuminate strategies that turn seemingly insurmountable problems into sustainable realities. Students use scaffolded readings of success stories from six continents, each with key human geography terms and guided questions, to prepare their case for presentation at a conference.
