Make the least change for the greatest possible effect.
"Small changes meet with less resistance than huge overhauls. I can't afford to retrofit my flat and moving is a big upheaval that I am not ready for yet. So, I can start by draughtproofing using old materials I have at home: pillows, unused itchy blankets, for example.
If I want to cut down on food miles and packaging I could grow salad on my windowsill, it would also cost me a lot less."
