As an abstract idea I think there is a reasonable argument to be made that the size of any contribution to a problem should be measured as a relative proportion of total influence.

The carbon footprint is a good example, if each individual focuses on reducing their small individual contribution then they could neglect systemic changes that would reduce everyone's contribution to a greater extent.

Any scientist working on a method to remove a problem shouldn't abstain from contributing to the problem while they work.

Or to put it as a catchy phrase. Someone working on a cleaner light source shouldn't have to work in the dark.
