Unfortunately nature sucks. One of the main philosophical questions of the past was why humans' internal moral code goes against what happens in the nature?

We need to eat to survive. Animals/plants/bacteria etc. need to eat as well. Why is killing/damaging plants more acceptable than killing/damaging animals? Why do we want to kill viruses that are eating our bodies? How many insects did you kill on the way to work today and didn't even notice? Simply no good answers :-( Hence cyberspace vs meatspace etc.
