That’s according to Peter Kalmus, an atmospheric scientist at NASA’s Jet Propulsion Laboratory, in California. Alarmed by drastic changes in the Earth’s climate systems, Kalmus, embarked on a journey to change his life and the world in the process. He cut his carbon footprint by 90 percent. How did he do it, what insights can he share as we attempt to live less consumptive lives and can he(or we) really be happy with a simpler lifestyle? Doesn’t it involve tremendous sacrifices? He offers a great roadmap to ‘being the change’.
