Bozeman Science: Environmental Economics
Paul Andersen explains how economic models, like supply and demand, can be applied to environmental systems. The market forces will not protect environmental services until proper valuation and externalities are established. The wealth...

Bozeman Science: Environmental Systems
Paul Andersen explains how matter and energy are conserved within the Earth's system. Matter is a closed system and energy is open to the surroundings. In natural systems steady state is maintained through feedback loops but can be...
