Are natural disasters ecessary for the earths evolution?
It depends how you define “disaster.” The processes which shape the topographic features of the earth include earthquakes, tsunamis and hurricanes. These are natural events. They are only “disasters” if they cause a loss of human life and property — features about which the earth and the processes evolving it care little to nothing. In the absence of humans and life, the natural processes would continue to change the shape of the earth, and none of these processes would be declared “disasters.” So technically, NO, natural events and processes, not natural disasters are necessary for the earth’s evolution.
