are you kidding? for ethical calculus? any allocation of resources. be that state resources, hospital staff and resources, humanitarian aid... . knowing its fundamental weakness; the slippery slope, generally ethical relativity, we must be on guard that the calculus cannot be applied when certain 'sacred' things, such as an innocent life, poorly-understood ecosystems, etc. are at stake. the calculus may be especially seductive in certain 'risk-situations', where the 'sacred' thing is placed under a certain risk, though huge benefits can be reaped if all goes well. for example, issues concerning genetic engineering. can we really relativise our ecosystem? our human bodies in their given form? if we do so in a minor way, what are the limits of this relativation? if they are relative, why stop at some arbitrary point instead of throwing it completely in the calculus? or say we engineer some kind of retro-virus to deliver a piece of genetic code that prevents cancer. suppose there is a *very* minor risk that it mutates and does the opposite, in some people. should do we employ it? should we invest resources in its development and dispersement? or this very real one (yes this one happens right now): there are salmons that are minorly engineered to grow extremely fat in a short time. they do so to the point of all kinds of deformities, and at times end up unable to breath properly anymore and suffocate due to their fat. however, this results in very cheap salmon feeding many poor families. yes or no?
and i mean, thats just for genetic engineering. the list is endless...
[edit] or this one: should we sterilize every couple after they had their first child until world population reaches an optimal level?
