I would say the first answer may be yes, human kind may the owner of everything. Nevertheless, human kind has no right as all to rule the Earth and "other living beings". if we consider things there are the 'civilised' and the 'uncivilised', I'm not talking about Men in general. We consider animals as the 'uncivilesed'.
Are we really civilised? mind me but wars, terrorism, fear and all that are our creation. I reckon that animals feel the fear, but not like us. and we want to rule them, to explain how they must live??? First of all it seems that they were here before us, and then sometimes it seems that they're largely happier than us, don't you think?
and finally, I think that Man can create, build, or kill(I know sometimes I'm quite negative!!
), but nature create and destroy. Look, hurricans, they go and take everything without considering Man. someone told me that because we are going against the nature, the nature takes a revenge on us, to show us that finally, IT rules everything. Maybe is it only a Man's impression to rules the world, because we want to rule overything and think that no one can interfere between us and the GREAT power.
