Ive tried so many things over the last few years, but so many are hard to keep up if you are living with not much/on a budget:
For a while we had a milkman, sadly they were expensive and didn't deliver on time. I spent more money on the phone to customer service, so we ended up giving up on this
Ive cut up old clothes, no good for chairty of giving away in rags
Use natural deodorant (better than shelf brought that even Dp uses)
Unfortunately my dp is used to his "creature comforts" so we brought bulk containers of shampoo/body wash, rather than lots of littles ones
Buying organic meat/clothing when finances allows, again all these things are more expensive!
I try to eat vegan/veggie - this one is more difficult when DP and family are very much 'meat' people
I buy most things- toys, clothes etc from shpock, charity shops etc, I try never to buy things 'new' its genuinely easy and amazing to find things you need for next to nothing, and is as simple as looking what people are selling close to you. - recently we got an American fridge freezer to replace our energy guzzling old fridge, for less than half the price of buying new. Good for us. Good for environment, I then didnt just tip my old one, but someone came to collect it to use -
The thing with being environmentally friendly, is that it is more expensive- eg. Buying 3 loose peppers in the supermarket is more expensive that buying a whole bag wrapped in plastic.
I can honestly say since learning about plastic and its damage to the environment, it has had a huge effect on my conscious mind for the environment, but most of the time its just so expensive to the average person, I can see why its never going to work.
I do what I can, and im always looking for ways to improve, but we live in such an ingrained throw away society. Its actually overwhelming all the time.
