I actually saw a demo of this at a community event I attended in Westgate, Kenya last year. And I realize something like this doesn't directly aid in wildlife conservation. But if conservation orgs provide resources such as clean water to the community with the understanding that they will in turn help with the org’s conservation mission, I believe that is the best way forward for long-term, sustainable community-based conservation. As Mark’s video says, helping the poor people in the world ultimately helps all of us, not only increasing our own security but also raising the overall global prosperity.
