Oh quickly on a (barely) related idea...
I saw a news story that a group of young men nearly died climbing Uluru (which I still want to call Ayres Rock even though it never has been in my lifetime) in Australia. The story had a number of interesting ethical dimensions. An emergency responder complained that the men had put themselves at unnecessary risk and considerable resources had been spent saving them. Moreover news reports also dwelt upon the fact that indigenous people now own the land and have asked people not to climb the rock. I feel two divergent and simultaneous gut reactions to this statement. One is that these indigenous people have been treated badly historically and this is just the latest of their rights being trampled on. Another is that nature, the world, and unique places should belong to all humanity, not one person or group. What right have they to say who goes there? Especially since their objection is based on superstition which I don't share. But should their beliefs be belittled as mere superstition just because I don't share it?
These are the kinds of complex ethical issues that hang on all sorts of historical, cultural, religious, social, economic (there's a complex economic dimension too to the stories I didn't even get into) and other factors that are impossibly difficult to reduce into a scientific utilitarianism.
What's Sam Harris's scientific answer to this issue I wonder? Should people be allowed to climb Uluru? Would be interesting to know the "correct" answer.
