Looking back - I find my marking a bit mean!
We do only 2500 miles a year in the car, never fly - what idiot would??, recycle or compost everything, have longlife bulbs, eat our own asparagus rather than Peruvian or, worse, US, do not have central heating, grow as much as we can & buy as little packaged food as possible, choose British & free range produce, & since we pay for water, we watch our usage ...............etc. So?? So the house is too big? Taking up too much of the planet? My fault? 18mx4.5m. Built in 1650, we must be re-cycling a previously owned domicile? And, at £3300 , we were very modest in money waste??
