I have always
Only boiled the amount of water needed to make tea/coffee it is a waste to boil more than you need economically and environmentally.
Rarely buy clothes, they set off as good clothes then sitting around in clothes then working in clothes then rags, this process takes at least 10 years and up to 20 years
I've never bought new toys just second hand ones and these are donated back to charity some toys are at least 5th hand
Never bought kitchen/bathroom wipes any sprays I buy are refilled with a touch of bleach and topped up with water until they die
Have always washed and reused freezer bags
Reuse tin foil
Don't buy take away coffee
Walk
Holiday in UK
Reuse if possible then recycle
Heating set at 19 degrees and only on in evening not over night.
Switch lights of when not in room, No point in buying renewable energy if you are still wasting it as non renewable has to fill the shortfall caused by us wasting it
Grow some veg where possible.
Don't do dairy but that's because I don't like it.
Turn taps off while brushing teeth
Compost anythingwe can
All little things that don't take much effort but would add up to a lot if every one did it
