As a teacher of English to real foreigners, you are outed Jenricks. 
As for PC points; I compost, recycle, car-share, make all meals from scratch with food grown on own allotment, heat house with woodstove, my furniture is mostly 'pre-loved' (okay then, secondhand), my clothes are mostly form charity shops - and the family motto is, 'Use it up, wear it out, make it do, or do without'. I look forward to receiving my PC points, which I shall of course donate to a charity.
