Welcome to Healing Earth, a free, online environmental science textbook for upper level secondary school students, beginning college students, and adult learners. We invite teachers around the world to use this resource in their classrooms and share their experience with us. Healing Earth is an ongoing project, so we hope that everyone—teachers, young students, adult learners—will join us in using and improving Healing Earth.

Healing Earth presents a unique approach to six major ecological challenges of our time: 

  • declining biodiversity
  • natural resource depletion
  • shift to renewable energy
  • water quality and availability
  • food quality and availability
  • global climate change

Unlike any other environmental science textbook, Healing Earth presents an integrated, global, and living approach to the ecological challenges we face on our extraordinary planet.

By integrated, we mean that the scientific knowledge presented in Healing Earth is joined by ethical analysis, spiritual reflection, and a call to action. The authors of Healing Earth consider this approach critically important. We believe the wisest and most effective response to Earth’s urgent ecological challenges will come from people who are scientifically literate, ethically grounded, spiritually aware, and motivated to act.

By global, we not only mean that Healing Earth’s content, examples, and lessons are drawn from different cultures and regions around the world, but also that the users of Healing Earth are members of these diverse communities. More than at any other time in the past, the range of today’s ecological challenges is planetary; thus, a global approach toward environmental science is necessary.

By living, we mean that Healing Earth will be monitored for content updates and postings on interactive forums. New knowledge about the Earth and its natural systems increases daily, so we aim to create an international network of teachers and students who are willing to join us in keeping Healing Earth current and alive.

The overall goal of Healing Earth is to help all of us grow into integral ecologists, people from every walk of life and region of the world who dare to imagine a healed Earth and are willing to put their hands, hearts, and minds to the task.

We sincerely hope that teachers will use this resource in their classrooms, that it will draw young students closer to nature, and that it will encourage fruitful discussions among adult learners worldwide. We invite all of you to link your imagination with ours and become members of the Healing Earth community.
