60 people over a decade dying is not minor. If a school killed two entire classes of kids over their k-12 education, that'd be a shocking amount of death. If a sports team lost 6 players every year we'd shut down the team instantly. Treating 6 deaths as minor is absurd and callous.

It only feels ok because it's so abstractly connected to pollution.

If this data center killed 6 people every year on site due to industrial accidents, we'd almost certainly close it. What Amazon warehouse kills half a dozen people on site every year?
