The document discusses building a healthy economy through sustainable development. It notes that available productive land per person has declined significantly over the past century due to overuse of natural resources. Sources like renewable and non-renewable resources provide materials and energy for livelihoods and the economy, while sinks assimilate wastes. Historically natural capital has been overused and undervalued, leading to degradation and low wealth in rural communities. Principles of sustainable development include being locally rooted and building self-reliance through cooperation. Green job categories discussed include restoration, efficiency/waste reduction, and renewable energy.
