Nature by Numbers

Patterns in nature never cease to amaze us. The short clip below gives some visuals on what we teach in our Permaculture Design Courses about how to use natural patterns to increase sustainability in human systems. For instance, on many plants, the leaves are spaced in a “Golden Mean” ratio around the stem – giving each leave maximum exposure to sunlight.  That same ratio in a thin spiral seashell gives it more structural support while keeping it light and mobile. How could you use these ratios to improve your design?  🙂
