I have a lovely DiL, a gentle Corbynista and supports ER, but visit their house and all the lights are on and the curtains open and the amount of food I have thrown away this Christmas because they and their family put food on their plates and then only eat half of it, so that there is no alternative to throwing it away is heart-breaking. I have also spent half the time walking around the house turning lights off behind them.
I have no time for ER they are the johnie-come-latelys to those of us, and there are a lot of us out there, who have been quietly and systematically trying to reduce our carbon footprint for over 20 years. During which time British territorial carbon emissions have been reduced by 42%.
It is delightful to be woke and aware of every issue, but you need to walk the walk as well as talk the talk
