I think quite a lot about this and related subjects. And I try and live with my values.
I don't buy UPFs on a regular basis (and by irregular I mean maybe one once a month or two months).
My house isn't stocked with loads of half used shampoos, conditioners, shower gels, etc.
I don't tend to buy clothes made with manmade fibres (because they're generally yuk, not because I'm religious!). I even make my own clothes every now and again. I also don't have loads of clothes just for the sake of having loads and buying something new every week or month.
And so on, I could continue, but it would be boring. I think you get the gist: I care about these things.
However, what I do do is drive a petrol car. My next car may be electric or a hybrid, but right now I drive all over the place using petrol. I don't tend to drive short distances, though, which is a small plus point.
I used to fly a lot, particularly to Europe, but many places it's a lot more pleasant by train, I hate the faff and waiting around at airports. But if I were going to Australia I'd fly as the steam ships no longer run. I've flown to Tenerife, this year I'll be flying too to another island with no direct ferry route.
I'm pondering flying to the Balkans as the train takes 24 hours or so. I don't mind that particularly, but I imagine the vast majority would prefer to just get there and start their holiday!
My thoughts about cars and aeroplanes are that they're necessary for a lot of things if you don't want to spend an inordinate length of time getting to places.
And I think telling people for whom a holiday abroad is a yearly or two yearly (or whatever) treat to forego that and either stay at home or go by a much more expensive and lengthier means of transport isn't very helpful.
Having said that, the types of people I can't stand are those who fly a lot, pay to offset the emissions, then lecture others about the problems with flying!
We could do with fewer planes in the air, but until on the ground (or water) transport infrastructure is there to provide alternatives, it's not going to happen.
