"Still the bible of solid, experiential and ecological approach to loving and knowing about the Earth we live on. And the systems of life that underly all life, including ours. It's a little harsh at the beginning in it's critique of other programs but most of the ones it critiques are those funded by big oil, big mining and big logging. So take it with a grain of salt. And focus instead on the earth ed approach and techniques. It works better than anything I've ever seen or used and I've checked out many programs. I highly recommend Earth Education." (Bruce Elkin)
