Sorry... I couldn't understand, maybe it's something from the language, what do you mean?
What I mean is that people are good at ignoring miseries and over time relativising a malady that was initially considered or perceived as catastrophic, or forgetting the state of affairs or pushing it far into the background.
I remember well my youth and later younger adult self and how we were scared off by school teachers and the media because of, for example, AIDS or the Chernobyl disaster. I did not directly experience any of the threatening effects or masses of people falling ill, and in the course of my life I began to take the horror stories less seriously, either because I was unable to do anything directly about them anyway or because I realised that the news reports were exaggerated.
Just the other day I saw an interesting contribution on the topic of global warming, in which the author had recited interesting horror stories from about a hundred years ago from picked-up newspapers. In it, journalists were already terribly worried in the early 1900s because the sea above Norway was not completely frozen over in winter. If you're interested, I'll send you the link with the video.
Is it clearer now what I meant?
Yeah, now I get it. :)
Don't worry, I know modern scientists are being just as alarmist about it today as they were then.
