When organisms exist within a well-functioning system that includes abundant energy (e.g., from the sun), clean water, fertile earth (soils and mineral resources), and a robust community of plants, they collectively produce materials vital for human life. These materials include food crops,
fibers, timber, medicinal compounds, and other renewable products.

By ensuring the balance and integrity of these elemental inputs, we foster
ecosystems that not only support the organisms themselves but also generate a continuous flow of sustainable, nature-derived materials for human use.
