Its we, who are responsible for the disasters, not the nature
Mahatma Gandhi very well quoted :
"There is enough in this world to address EVERYONE's need but not to satisfy ANYONE's desires"
In this beautiful world of god every thing - living and non living exist in sync and have its own right space. As long as every creature is allowed its own share of resources the things go smooth but the moment one creed tend to seize more than what is meant for them the ecological balance starts getting disturbed. In their drive to have more and satisfy the endless desires, human being have created this imbalancing gap where some of the integral part of the ecological cycle have been deprived off of their share of resources and the nature, in its drive to make good the loss suffered by its components is restoring back the system to the situation in which it is supposed to be and we feel as if its a calamity but its nothing but just a system restore to set the thing in the way god wants them to be. A very innovative description of god was taught to us which says BHAGWAN means:
BHA: Bhoomi
G: Gagan
W: Wayu
A: Agni
N: Neer
