The doom and gloom is gonna be there for a while, and it should be there for a while, because things are still gonna get worse and we need to know the important details, like how, where, and why, so we can properly assess and address issues. Sometimes though, I think they paint the doom and gloom too thick to the point where it might actually cause more harm to attitudes than good. To me, there's a balance, like it's possible to say "atmospheric carbon buildup is fucking nuts, here's why, and here's what people are starting to do about it." Imagine if people payed as much attention to reforestation or regrowing carbon sinks as they do Elon Musks' projects like SpaceX. Shit like that captures the imagination, it excites and energize people. It is absolutely possible to create similar excitement around environmental issues.

As for job creation? Dude, I totally agree. Screwing up the planet is gonna create a whole mess of jobs out their, from disaster relief and reconstruction to medicine to ecology projects. Personally, I'd rather it not be necessary, but you're right, there will not be any shortage of work that needs to be done.
