"We should be aware of current events" - should we? Why? There is an avalanche of current events, I've stopped paying attention and I still find out - its impossible to avoid, I see absolutely no value in paying attention to things that I'm just not interested in. War in Iran - yep, battle of the stupids - it just doesn't matter, there is nothing I can do about it, best to ignore it all. I have friends obsessed with the news, wake up in the morning and watch the news during breakfast - they discuss it endlessly, get a lot of angst from it, its all just noise to my mind.
Cause people unaware of those events vote to cause those events.
Large groups of people all contributing small amounts towards a goal none of them could accomplish on their own is the only way any of those things ever get done.
Doing what you feel necessary or useful at a local scale is still empowering. Understanding that the effects will be mostly local as well is a good thing, but choosing your battles is perfectly healthy.
