EcoSystems applies energy technologies to do more with less. Going beyond efficiency, we employ solar energy to sustain human culture without drawing down our natural resources -- our "natural savings bank."
Virtually all modern economic systems are based on the continued exploitation of nature.

On the brighter side, stewardship practices are emerging. At the end of the day, cultivating economies will be more fruitful than at the beginning of the day -- with more fertility, more soil, and a brighter future for the next generation.
