Gandhi said: Go To Villages Now IT companies and organizatons move to villages for many

reasons like cost cuts, increased productivity, cheaper resources

But need to green rather than eco-damage

A layman would scarcely understand what the machine does and how it does.

Gandhi believed about hand-spun clothing:

“The art that is in the machine-made article, appeals only to the eye; the art in Khadi appeals first to the heart and then to the eye.”

So concern for humans rather than just luxury and technology

Care for the country, Green family and future Generation Teach kids the eco-friendly ness and natural

living rather than Video Games and iPads
