Permaculture is a connecting system between disciplines, not a collection of isolated subjects. Geoff Lawton emphasizes the importance of understanding core scientific principles, especially climate data, and grounding all design in ethics. He cautions against unproven sciences and highlights the potential dangers of unchecked technological advancements, stressing the need for a sensible, proven approach to design. Ultimately, the goal of a permaculture teacher is to empower students to become better designers and consultants, fostering a deeper understanding of the interconnectedness of science, ethics, and climate.
