In 2012, The United Nations General Assembly proclaimed March 21 the International Day of Forests.
The Day raises awareness of the importance of forests. The organizers, United Nations Forum on Forests, the Food and Agriculture Organization of the United Nations (FAO), the Collaborative Partnership on Forests, and other organizations, encourage tree-planting and other celebratory events.
This year’s theme is Forests and Biodiversity.
An Earthship is a passive solar house. Michael E. “Mike” Reynolds, a New Mexico based American architect, developed Earthships.
Earthships use both natural materials and unconventional building materials, such as automobile tires. Earthships utilize everyday trash items like aluminum beverage cans, beer cans, plastic bottles, and used tires. These materials are mortared together and then plastered over into a brick design.
Earthships require a permit. They can be completely off-grid or partially off-grid.
Earthships use solar panels and geothermal cooling. They provide electricity, potable water, contained sewage treatment, and sustainable food production.
