it takes time. I lived in a bubble for over 30 years, until I stumbled upon the guy from yt I mentioned above.
in dec 2022 he made 2 docus, 1 about the fur industry and 1 about the milk industry.
I became vegan after those 2 videos. slowly I also read more about that stuff.
becoming vegan was a game changer for me (and my health also).
because if u are vegan, u are bound to read up more about micronutrients etc
you also become aware of all the bad things happening.
if u have time, you should watch 'dominion' with your mum. the full movie is on yt.
but it shows all the animal cruelty happening in animal farming.
its really hard to watch tbh, and as I`m not sure about your age, u better watch it with somone together.
