Forty percent of the world's population live in earthen dwellings. The most enduring earth building, Egypt's adobe Ramasseum, still stands (though damaged) after 3,300 years. In China's Fujian Province there are 30,000 earth buildings, dating mostly from the Ming (1368-1644) and Qing (1644-1911) dynasties. India's oldest earthen building, the Tabo Monastery in Spiti Valley, Himachal Pradesh, built in 996, is still in use, having withstood Himalayan winters for a thousand years.
With the 20th century came the use of concrete, steel, treated lumber and all manner of synthetic materials, with serious consequences. Our rapacious thirst for lumber is stripping forests. And for every ton of concrete we produce, we generate one ton of greenhouse gas emissions. More pollution is caused by the need to transport these materials and to heat and air-condition the poorly designed buildings. Furthermore, many modern building materials continuously outgas toxic chemicals into the home or workplace for the inhabitants to breathe. Concerned builders are going "green " and turning back to the oldest building material: earth.
Imagine a healthy home, heated by the sun, cool in the summer without the noise of loud furnaces and air-conditioners. Such a home supports a non-polluting, sustainable economy and pays for itself over time.
