Wondering what I should do after alevels.

Recently I've been thinking that having literacy in STEM subjects is more essential than having a humanities or social science degree. Particularly because of the most pressing issue facing humanity: (renewable and nuclear energy development, more efficient agricultural processes and space travel) - all kinda linking to climate change. I feel as though I would be able to make change with for instance a history or politics degree but in a more indirect way than with for instance a mechanical engineering degree. I also sometimes felt quite demotivated when studying history for instance and wonder if it's because it's not as directly applicable to a career as a more "trade" ish degree, for instance, mechanical engineering... However I have also wondered if this conception has been kinda socialised into me in a way as in my school there were far more people studying and interested in stem. Sorry for the long largely unintelligible schpiel would be really useful if anybody had any tips on what my options could be or if they were ever in a similar situation.
Btw I finished my alevels all in non stem subjects last month and am taking a gap year
