Intelligently, ethically and intentionally designed living systems are the only way we as humanity can be a true benefit to the physical earth we inhabit. From where we get our water, to what happens when we're done with it, if we build soil or destroy it; the simple act of living can create rich ecosystems if we design through permaculture.
Shifting from feeling and acting as a burden on earth to benefiting life through living in well designed systems is a huge liberation from a painful mindset and a safety to oncoming disaster.
Sam has a strict design policy and will only design for those who have an intention to implement the design created, or a better one. There are a variety of ways to make the design physically manifest: a contract job with Sam and various workers, a workshop facilitated by Sam to create a broader educational impact, or through your own personal labour with online tuition for concentrated personal learning. It just depends how much you want to learn, want to share with others, have time for, and your budget.
