I'll preface my answer by saying that "world media" (as mentioned in the parent post) and US Media are different things. If the goal is internal political pressure and accountability then sure US Media attention has some value. World media maybe not so much.
1) alas, in the US context its not really "special". There seems to be an article every 5 minutes about some business prioritising profit over the environment. I agree that its terrible, but unfortunately not special.
2) probably not. But media attention won't change their danger status.
3) absolutely not. Environmentalism, climate change, the ills of profits before environment are well documented and we'll understood. Politically the nation seems divided on thus topic. In an absurd way this event adds very little to the conversation. I think that's bonkers, but I don't think this event will change too many minds.
4) working conditions are already regulated. There are people in favour of more regulation, and some in favour of less. The US has some of the weakest labour regulation in the world (in some respects.) So yes, I think better regulation would be a desirable outcome. Then again that fire is already burning well. This event does little to fan the flames.
5) short answer is, unfortunately no. The root cause of this is profit over environment, profit over people. That's a particular US condition and it is intrinsic to the American psyche. Media attention of this event won't change that, and there's certainly no shortage of upcoming preventable ecological or human disasters waiting to happen.
I'm not saying I'm happy with the status quo, but it's not like this is surprising, or frankly even newsworthy.
It's life-changing to those folk affected, but the rest of the country don't really care. Which is whacked.
Explain how media sensationalism helps 1-5. The people are already very aware, authorities are already aware, you're already aware. so we can't use the awareness angle.
We have a very different view of how media ends up affecting outcomes. I haven't seen many positive outcomes from media involvement, the cycle is too quick and the viewpoints heavily biased.
1) Do you think that a town getting poisoned is not "special"?
2) Do you think that the 5000 people that lived on said town are out of life-threatening danger?
3) Do you think it's only said town and said 5000 people that are threatened by this?
4) Don't you think that working conditions need to be regulated in order to be safe?
5) Don't you think that this disaster could help us prevent other ones?
