You can split up every single industries/topics/&c. into "yeah but it only use 1.5% of energy", "yeah but it only produces 1.5% of the co2"
Guess what happens when you add them up...
>Guess what happens when you add them up...
I'll guess, they add up to 100%?
I don't see what's the insight here.
This kind of logic only works if the percentages for each industry are all equally that small, so you can treat them as all equally bad, but they are absolutely not.
