I guess I feel slightly bad as over the last four months I have added 8.5kg of carbon dioxide to the atmosphere. I did this by mostly eating less and exercising. I also added 1.5kg of water into the world’s system. Both of these measures should be carbon neutral I think. The carbon I ate over the last few years and the water was drunk – I mean how else is that stuff going to get into my system? The tricky thing now is to maintain my input-output balance and get clothes that fit me, once we are out of lockdown.
