5-6 years ago I would have said "office work" -- not nec the sort that is paper pushing and silly meetings but mostly working in an office, the best possible setup to make sure that no deep work gets done.

But then 'rona and WFH revolution, every pleb and schmuck gets this. ("Ah, actually, I can do more and perform better if people DON'T interrupt me and I can cut out unnecessary commutes!")

So, instead, I'll say -- with a wink to the experts -- the danger, impact, and effective outcome of climate change. Won't be a big deal under any scenario. Green is a fad that will, thankfully, go away.
