I don't have children. I haven't flown for 21 years.
We only eat meat produced in the UK and only eat outdoor-reared pork and free-range chicken and eggs. Much of our meat, poultry and eggs comes from a farm shop 2 miles from our house.
We keep an eye on the food miles of fruit and veg. We buy British where possible and wouldn't dream of buying green beans from Peru or similar produce. I'll choose apples or stawberries from the neighbouring county rather than those from Worcestershire 180 miles away.
I don't buy fast fashion and we keep stuff until it breaks or wears out. We only drive approx 6,000 miles a year, and around 2,500 of those are work miles, that I don't have a choice about. We recycle as much as we can and have a wildlife friendly garden.
I'd hazard that our carbon footprint compares quite well with that of a couple of vegans who bog off to Thailand every year.
I'd also like to point that in parts of the country that are grazed, particularly sheep-grazed, the landscape has been created by millenia of grazing. The unique flora and fauna of this land would soon cease to exist if grazing stopped, so I'll keep my skylarks, bee orchids and blue butterflies and keep eating locally-sourced south downs lamb in the interests of bio-diversity.
And if these chalk hills and upland areas, like the Yorkshire Dales, stopped being grazed they would quickly revert to scrub, which would be very sad indeed.
