I received this link in an e-mail from the director of CWF this morning. The Cambodian Rural Development Team plans to install 15 more bio-digesters--yes, the magical concrete boxes that turn poo into power. For 15 families, this means that they will have electric lights and gas cooking stoves (instead of using kerosene lanterns and wood-burning stoves). Implementing biogas in rural Cambodia helps slow deforestation and offers a sustainable solution for two basic problems.
So if that extra cash is burning a hole in your pocket, or you just feel like making a big difference in someone's life today, this is my recommendation.
Sorry, poo donations not accepted.
