MEET THE TEAM
Joanna Campe
Executive Director
As the founder and Executive Director of RTE, Joanna Campe raises public awareness of the crucial role of soil remineralization with finely ground rock dust, sea minerals and other natural means to regenerate soils, forests and stabilize the climate. She promotes partnerships with foundations and educational institutions, government agencies, international development agencies, the private sector, and NGOs. She has decades of related conference participation, project organization, media development, authorship, public speaking, professional networking, policy advocacy, and public awareness building. She has co-authored several research papers and is the co-editor of Geotherapy: Innovative Methods of Soil Fertility Restoration, Carbon Sequestration, and Reversing CO2 Increase.
In the early 1980s, Joanna read the book The Survival of Civilization by John Hamaker and Don Weaver and what had for her previously been “dirt” under her feet became a vast micro-universe that is the basis of all life. She recognized the tremendous importance of John’s work and joined together with him, Don Weaver and others to get the message out.
Don Weaver
Co-Author of The Survival of Civilization
Don has for 37 years been an ecologist, researcher, writer and organic grower concerned with the health and survival of humanity and the Biosphere. Humanity must quickly transform into the wisely generous species on Earth, if the growing momentum of eco-climatic and health degeneration is to be reversed. He began working with John Hamaker in 1978. John’s early writings inspired an understanding of how local and global soil remineralization with natural gravel (mixed rock) dust can enable us to perpetually grow high-quality crops and trees, the natural foundation for regenerating the socio-ecosphere. John and Don subsequently collaborated to author The Survival of Civilization, produce 11 issues of Solar Age or Ice Age? Bulletin, and numerous articles for the magazines Remineralize the Earth Magazine (1991-1997), Acres USA, Living Nutrition and more. His email contact is: earthdon@yahoo.com
Since John Hamaker died in 1994, Don has continued sharing these crucial insights. From 1997-2002, he researched and wrote To Love And Regenerate the Earth: Further Perspectives on The Survival of Civilization, which includes additional Hamaker writings in its 540 pages. Both Hamaker-Weaver books and Weaver’s Fruiticulture remain free at www.soilandhealth.org.
