It's a bit of a tangent, but this is basically the question behind one of the classic cognitive bias studies on "scope neglect", https://en.wikipedia.org/wiki/Scope_neglect https://en.wikipedia.org/wiki/Scope_neglect - "In one study, respondents were asked how much they were willing to pay to prevent migrating birds from drowning in uncovered oil ponds by covering the oil ponds with protective nets. Subjects were told that either 2,000, or 20,000, or 200,000 migrating birds were affected annually, for which subjects reported they were willing to pay $80, $78 and $88 respectively.[2] Other studies of willingness-to-pay to prevent harm have found a logarithmic relationship or no relationship to scope size.[3]"
