To answer your question, yes, I think it's really important for adults to know what's going on in the world. I watch lots of news on TV, and read a variety of newspapers online. I always have the news on when I'm getting up, having breakfast before work, often in the evenings and at bedtime.....
It is difficult to gain a balanced perspective because every type of news coverage has an 'angle' and a bias, I think it's important to realise this. To counteract the bias I tend to use multiple sources for my news...I watch BBC, ITV and Channel 4 but also RT, Al-Jazeera, Sky.... I want to know what is happening in the whole world, not just the BBC's take on Boris' parties (!!) Channel 4 has some good news documentaries but world news is better covered by Sky and particularly Al-Jazeera, who often cover the Middle East, African and South American news stories which our own TV channels don't even follow. DW is German and can be watched online and gives a different take on European news, it's also possible to watch RUV online which is Icelandic and covers news from a Scandinavian perspective, as does NRK Nyheter (Norwegian).
I think to be a global citizen these days requires us to be informed. It means knowing what others in the world think, even if we don't agree with it at all. For instance, RT is a Russian news source and obviously gives a completely different perspective/argument for troops amassing outside Ukraine (or any other story which involves Russia). They are also heavily biased against the USA. I seldom agree with their views but I am interested to hear their "take" and how they justify their actions.
I'm not very interested in showbiz stories and I ignore social media stuff about celebrities, I am more interested in national and international politics, climate change, humanitarian stories, science breakthroughs, travel, environment.....
Everyone on MumsNet appears to hate the Daily Mail but I read it online, alongside the Times, FT and Guardian. Each paper gives a very different perspective on the same story and somewhere in the middle is the balanced view. The Daily Mail is sensationalist and often spouts tripe, but it has a readership of around 2 million (I believe) and therefore I read it more to understand what a section of our population is digesting every day, and which probably helps explain why certain people hold certain views/opinions. The same could be said of papers like the Times and the Guardian.
