Not trying to say we shouldn’t consider this, but it seems like there’s bigger fish to fry first (assuming we can’t fry them all at the same time).
They don't seem low at all to me. And a quick search suggests that malnutrition probably causes fewer deaths [1] (note that it's counted for all people here, not just under 5).
And in places like India and SEA, where malnutrition and violence are less of a problem, air pollution stands out even more.

That is properly fucked up for children under 5. They start with absolutely clean lungs and the damage compounds so much they die from it. Think about all the other age groups that have some other horrific numbers.
Not per 100k, per 1000.
That means that for every child that dies from air pollution, ~600 more die from some other cause.
To be fair, most causes seem related to terrible living conditions, so everything probably improves or degrades together.
