>But yeah lots of people don't really buy into the idea of their small contribution to a large problem being a problem.
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.

Right, I think you have responsibility for your 1/<global population>th (arguably considerably more though, for first-worlders) of the problem. What I see is something like refusal to consider swapping out a two-stroke-engine-powered tungsten lightbulb with an LED of equivalent brightness, CRI, and color temperature, because it won't unilaterally solve the problem.
