Food justice and security, water security, renewable energy, urban farming, sustainable agriculture, land restoration, organic foods, gardening, local and alternative currencies, bartering, peak oil, transition off of oil dependency, permaculture, wild foraging, homesteading, biomimicry, sustainable cities, social ecology, skill building, ecopsychology, self reliance, ecovillages and intentional communities, conservation biology, biodiversity, CSAs, ecosystem health and ecology, natural building, zero waste systems, shifting global consciousness, earth stewardship, indigenous ways of life, wilderness survival, ethnobotany, alternative health care, nature crafts etc.
If you or your organization have upcoming events to announce, or if you'd like to join the list for weekly updates, please contact me at gsquared1234@hotmail.com
