SIR – It’s no surprise that Sir Paul McCartney has extolled to us the ‘virtues’ of not eating meat for one day a week as our contribution to saving the planet from climate change.

Of course, it does rather defeat the object if, instead, we eat more fruit and vegetables raised using large amounts of power from fossil fuels or have been imported over great distances also using fuel, especially by air.

As a possible pensioner himself, he should try managing on the old age pension like the rest of us. We have no difficulty in not eating meat for more than one day a week – we have no choice.
