It's an interesting book, sometimes many things can't be changed, for example in Mercadona everything comes in plastic and sub-plastics haha.

But if I always buy everything from a greengrocer not from Mercadona, I avoid plastics, I take my own bag or trolley. I walk a lot unless it is too far then I use the bus. I try to use as little plastic as possible and if I want to move out of the city centre! But renting is very complicated at the moment.
I want my own vegetable garden, my own fruit trees and all that. I used to have it before and I will work to make it happen.

It's very difficult sometimes to change everything unfortunately.
