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
He also said: Grow tree and plants in the computer center and labs Plants absorbs pollution and CO2 emission but releases O2.

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
