I think the metaphor of mortality really hits the nail here. I've been reading and writing about the doom and gloom for most of the last year and in summer (during the heat waves and wild fires) I simply crashed. I needed to seek medical help because of burnout. I went on a vacation, enjoyed a flight with an airplane, came back home rested, and avoided this topic for the next three months. Now I'm back and I feel the same shitty feeling in my chest again. I ordered Greta's new book, but I had to put it away. It is tooooo fucking much for one soul to handle. And collectively we're doing shit.
The other metaphor you've mentioned is smoking and drinking. Few of them really quit before a stroke or a heart attack. That's what it will take for us. But by then, it will be too late. The only thing that gives me some degree of hope is that at least some form of geo-engineering will be ready to use by then. Because in terms of real prevention, nothing will happen. Only cheap hashtags, marketing, brainwashing, and plain denial.
