O2 Sustainability Treehouse

O2 Sustainability Treehouse has been making people talk! Featured on Treehugger, Inhabitat, ecogeek, Popular Mechanics, and Dwell to name a few. People are talking for good reason - these spheres aren't your father's treehouse. They are suspended in, rather than nailed and bolted to, the tree, causing harm to it. Also the buildings are made with 100% sustainable materials!
Also, they get big points for having a heart!... from their blog....
This August 2009 O2 Treehouse Eco-Tourism will be joining forces with SYRV, a non-profit organization dedicated to enabling travelers and contributors to support developing countries through education, social development, and local engagement.
Two groups of volunteers from SYRV will travel to the village of Jiquilillo & San Juan del Sur, Nicaragua, from August 5-12, 2009 and August 19-26, 2009. One of the projects the volunteers will be partaking in, with the local communities involvement, is the development of the O2 treehouse to be built on the property of Montys Surf Camp in Jiquilillo. 100% of the proceeds from guests staying in the treehouse will go to sustaining and developing SYRV’s on-going humanitarian efforts in Jiquilillo and the surrounding Chinandega area. This includes sustaining clean water projects, electricity in schools, school donations and more.
In order to build this project of giving and love, we need your help. All moneys donated to SYRV on behalf of O2 Treehouse will help make this happen. We can’t do it without your support.

SYRV has partnered with Project Lagoon (Proyecto Laguna) a US registered charitable foundation with 501(c)(3) status, therefore a your donations are tax deductible.
