It's much more likely is that everyone's well aware of climate change (I'm sure I've read many hundreds of articles over my lifetime), but this is the first many people have heard of SV pollution (it certainly is for me).
I'm missing something.
What exactly is the agenda?
Maybe front page rank isn’t about how important or pressing the story is?
2) It's generally frowned upon to comment about "why isn't this story getting more upvotes", etc. In other words, it's not adding value to the conversation, so please refrain from doing so and use the upvote/flagging features if you feel outraged something isn't getting the attention it deserves.
3) If you don't like something on the frontpage then don't upvote it. Simple.
4) I don't live in SV, but many people who are "Hackers" do. The article specifically targets tech companies who have offices in SV and are impacting the environment.
