‘ The uncertainty is constant’ is a fact. Due to our lifestyle, all of us are prone to risks that were not even assumed to exist in older days. The introduction of newer technological changes such as wireless network, 5G etc., have increased the risks of uncertainty given our limited knowledge of new technologies and its impact on health of human and ecosystem. In addition the natural calamities such as forest fires, floods and earthquakes have added new dimensions in these uncertain times.
