> In our day-to-day lives you can basically ignore all of it
This is true for people who are able to detach from the events of the world, but that is not a universal skill.
Plus a lot of the concerns I listed are not just news you hear about - they are things people are living on a daily basis. Just the other day a guy walked into MSU, about an hour away from me, and killed a bunch of people. For some you can tune that out and carry on with your life. For others, notably people in the community or families who were directly impacted, it's traumatic.
The plume of shit in the air down in Ohio is also about an hour from me. It's not just a news story, farm animals are dying. That is someones livelihood and its indicative that the environment is toxic. That would stress you out, wouldn't it? Should I drink the water? Do I need to move? Can I move? Can I even sell my house now that the local area is toxic?
I think you can stick your head in the sand for a certain amount of time but at some point you need to come up and look around at the world we are creating and become proactive instead of just watching it crumble.
