Sincerely, do not read this if your mental stability is tenuous. Basically details the numerous factors, environmental and otherwise, that are all pointing to societal collapse by the 2040s. I could barely get through it without feeling nauseous. There's some minor liberalism regarding China but it's more of a footnote than major focus.
You don't need to let prepper paranoia take over your life to have at least some basics covered, get a month or so worth of long life food and rotate it occasionally. Get some water filters or something to make water safe. Get a cheap gun and a small stock of ammo. If you did all this you should hopefully at least be able to weather any short term issues.
If you have a garden dig it up and try growing food, it's a fun hobby and can save you money so it's worth doing anyway. This and some water collection capability and you will be very resilient to a lot of issues.
