contrary, human progress seems contradictory to environment security. To keep up both at the

required level is a challenge to be addressed by one and all. One of the ways to curb the climate

change may be suitable scientific innovations, while the other may be the Gandhian perspective on

small scale progress with focus on sustainability.
