Eco tree houses - the homes of the future

Tree houses grown specifically for modern living could be the eco-homes of the future. Scientists from the US and Israel have developed the trees that can be shaped into the structure of innovative homes.
The ingenious tree houses naturally provide shade and can also be used to process waste and reduce carbon emissions. The researchers at Tel Aviv University and a branch of the Massachusetts Institute of Technology are confident the first prototype home could be ready in just ten years.
