Mostly prepping to go without food, electricity, travelling or communications because of sabotage of vital infrastructure (in Europe and UK is happening on a weekly basis) and climate catastrophes which are regular in the UK since 2020(ish) and increasing. There are also potential lockdowns because of pandemics (e.g. measles from US). Also Brexit Britain is now inoperative in terms of food safety, really, since it relies on mainland Europe food imports to survive. If something fails or there’s a mega-storm, supermarkets will be empty for days like they were in 2018 or 2020.
