I’m not your target demographic but it’s not really a stretch to say that pretty much everything that’s happening today has happened before and will keep happening. Like others say it’s mostly because there is more coverage (and maybe some more nuance causing more opinions). Back in the 50s the US started fighting in Korea and pretty much the entire US could see why and supported it. Then when Vietnam happened, there was a bit more coverage which also caused more dissent. Since then I think petty much every 5 years or so the US has been fighting wars in the Middle East. The fight with Iran is nothing new (look up Iran-Contra for instance).
Environmental concern has been around for well over 60 years and yes, we are a lot further along but by now the smart money is on people will never be able to steer it in a positive direction so it’s pretty much damage limitation where possible.
In the end it’s not really about how fucked up global events are, it’s more about finding the light in when they all seem a bit less fucked up than it used to be.
