I buy everything I can from my local no-waste shop, including tooth powder (instead of toothpaste) and recyclable toothbrushes (they collect them in a box), shampoo (I have switched to solid, but nobody else at home has), flour, spices, pasta, rice, dried legumes, etc. It's frustratingly expensive, but I can afford it, and believe it's important that those of us who can should do so, until it becomes more widespread and affordable.
Fruit and veg come from a local delivery scheme, from various local producers, delivered all jumbled up in cardboard boxes (ie no other packaging). We don't eat much meat, but what we do comes through the same scheme, so it's organic and local, albeit in plastic. I would like to be able to take my own containers to a butcher's, but as I want organic and local, that's impossible round here.
I make my own cleaning products (ingredients bought at no-waste shop). I have used white vinegar instead of fabric softener for years. I also make my own body butter and handwash.
I spray DD's hair with a mixture of apple cider vinegar and tea tree essential oil; it's a brilliant detangler (smell fades as hair dries).
I try to take my lunch to work, but when I have to buy something, I choose on the basis of minimum packaging. It's usually something to take back to my office, but when I go out for a casual lunch with colleagues I no longer have a drink; tap water isn't served in this country, not because it isn't safe to drink, just to force people to buy bottled and canned drinks, and I now refuse to do that.
Other things aren't changes because I've always done them: dry washing outside wherever possible, compost everything we can, use public transport where possible (though we have to drive to the station as we live in the country)...
I do think that bigger, systemic changes are necessary, but I also believe that we all need to take responsibility at our own level.
