aboriginal Europeans' TFR is about 1.2 and falling. even if did remain that high (it won't!), 750M will become <100M in 100 years and <10M in 200 years. Europeans have already adopted the most effective strategy imaginable to fight klimat change -- extinction.
so I don't think it's fair to scold Hans from Hamburg over his carbon footprint. Abdul from Mogadishu may emit less CO2 over his own lifetime, but each of his 5 children will have 5 children, and no one will scold him for it.
yes. does that not make sense to you? unless Hans is a young global leader who flies his private jet to Davos every year to urge proles to eat ze bugs, his carbon footprint will be less than that of someone with children.
(I would use something other than "Abdul from Mogadishu" as the counterpart, but the only remotely European people not going extinct are some subgroups of Israeli Jews.)
not a single European country has the TFR anywhere near 2. with the median age now reaching >=40, the TFR of 1.0-1.5 means rapid and irreversible decline. is this news to you?
yes, yes, very virtuous of you, now back to my point: why should Hans give a flying fuck about climate change if he will have no descendants to suffer from it?
