I do wish people would stop pissing on each other over small changes already made, regardless of how tiny they might be in the grand scheme of things. Yes, we all could do more, but everyone has to start somewhere. Perhaps it can then be built up over time without becoming a huge inconvenience.
My lifestyle is relatively eco-friendly, not always by choice, but often due to monetary issues. I buy a lot of things second-hand, including furniture, toys, books (we use the library weekly, too), my car is second-hand and old enough to almost count as vintage. Old clothes and bedding get put into a sewing box and get made into one-off costumes for silly things like princess parties and whatever else kids get invited to that normally has people buy polyester costumes, which get thrown away after one use. I'm lucky that I am a reasonably gifted seamstress, albeit self-taught and not always picture-perfect. I cycle or walk to the shops unless I do a big weekly shop. I line-dry, even in winter.
I cook from scratch and seasonally where feasible, buy wonky fruit and veg, I do eat meat but never throw any out (e.g. my duck roast lasted 3 meals) and have taught my kids to respect the animals we eat by not wasting any meat.
My garden is attracting an awful lot of wildlife, partially because I planted consciously, but also because I often don't have the time to weed and maintain it to manicured standards.
And yet, no doubt plenty on here would slate me for my lifestyle. I drink tea and carbonated soft drinks, my battery use is high because we use console games and don't have a charging cable (yet), I colour my hair, drive a petrol car, keep small pet animals (not carnivores), heat my home, buy the odd trinket for the hell of it and plan on a big holiday some years in the future in Asia. Oh, and I have kids.
The point being, there is always more that can be done and no doubt we will all be forced to make big sacrifices in the future. But allow us a tiny bit of life, in the meantime, while we get to grips with what is and what isn't reasonably easy to do. I am sure, over time, many more people will be forced into the kind of money-conscious lifestyle that the poorest (of which I am not one, I might add, just very careful with money due to being a single mum) already lead.
