Nature and the fall of man

There are some Christians who hold that before the fall of man nature was different from what we see today. Animals were not wild but tame and peaceful, and they did not eat each other. There were no diseases and there were no natural disasters. This was the condition of nature in Eden. However, when man sinned and was turned out of Eden, nature changed and became what we see today, in which disasters and diseases are common, and animals eat each other.So this view explains that the reason for human suffering due to events in nature is that man brought such a state of affairs on himself. It is all the fault of mankind.Some Christians do not, I think, hold this view. If one believes in evolution, for example, I would think it would not be possible to hold the view that nature changed in this way. So my question is for those Christians who do not hold the view that nature changed in the way I have described. If the current state of nature is not due to the Fall, then what is it due to? Why does God permit these terrible natural events to occur?
