Fluff or Really meaningful

There are news and information and rumors about all parts of life, just like how the internet spreads information (excluding echo chambers). Taking most recent headlines about changes to Gulf of Mexico to Gulf of America. From this specific action, are there going to be severe changes to the Gulf region for oil drilling or just a small front towards a distraction but will soon have a larger ripple effect. Like there are other headlines; wars, genocide, Ebola outbreak, tuberculosis outbreak, measles outbreak, bird flu. All of these one way or another are true but somehow dwindled down. My question is in these hyper sharing and information consumption, which ones are more imperative and follow up will be necessary?
