Every classroom and discipline, says Grotzer, can incorporate concepts related to environmental education. Both the ethical considerations — the notion that we have a collective responsibility for the common good — and the ideas of complex causality percolate throughout the school day, from history lessons to literature analyses to disputes on the playground. Learning to dissect these complexities and create sensible solutions can help develop the critical-thinking skills necessary to understanding the challenges of environmental stewardship.
