In a moment of idle curiosity I wondered how much CO2 we breathe out each day, since almost everyone now seems to think that CO2 is poison. (It isn't folks!)
Well the internet provides everything and on a web site somewhere (very scientific) it said the average persons breathes out about 450 litres of CO2 a day or about 900g.
You may wonder if it is worth holding your breath to improve things (hint, it isn't).
For a comparison a 2 litre VW Golf emits 145grams per Km. So if you stop breathing for a whole day you can drive your car 6.2Km or about 3.85 miles. I think I'll keep breathing then.
