Don Weaver
Educator/Planning Consultant/Installation & Maintenance Manager

After concluding an enjoyable dedication to competitive athletics, primarily basketball, Don Weaver has devoted the past 33 years as an ecologist, researcher, writer, and organic grower concerned with improving the health of humanity and the Biosphere. He has enjoyed those 33 years of relatively natural living and vibrant health on a 100% raw vegan diet, to test out the idea that a good gardener should be able to obtain all his/her nourishment from our “Once and Future” Garden of Eden without asking other animals to give up their lives. Don thinks the craze for raw “super­foods” is a natural desire for those seeking “superhealth,” but reminds people through his talks and writings that if we’ll first go to the small trouble (actually a big joy) of creating “super soil,” then all our foods can and should be “superfoods,” which with intelligent use can end the current global malnourishment of children and adults.

Don thinks that humanity must quickly emerge as the wisely generous species on Earth, if the growing momentum of eco-climatic and health degeneration is to be reversed. In 1978, he met the brilliant ecologist John D. Hamaker and learned how local and global soil remineralization with natural gravel (mixed rock) dust, to grow high-quality crops and trees, is a powerful and practical foundation for regenerating the socio-ecosphere and preventing catastrophic climate change of more than just a “warming” kind. John and Don subsequently collaborated to author The Survival of Civilization, produce 11 issues of Solar Age or Ice Age? Bulletin, plus write numerous articles for the magazines Remineralize the Earth, Acres U.S.A., Living Nutrition, and others. Buckminster Fuller, considered by some the most brilliant mind of the 20th century, praised The Survival of Civilization as “well done, completely convincing.” After John Hamaker passed away at age 80, Don spent five years researching and writing To Love And Regenerate The Earth: Further Perspectives on The Survival of Civilization, which includes additional Hamaker writings in its 540 pages.

Based in Northern California, for over 40 years Don has planted and tended numerous Fruiticulture gardens and orchards in mineralized soils and promoted and the establishment of Earth Regeneration Centers worldwide. Don also assists the non-profit Remineralize the Earth (www.remineralize.org).  Contact Don if you are interested in Fruiticulture planning, planting and/or maintenance, or if you’d like him as a speaker at your health or ecology conference.
