@philippa smith2 So you live a totally basic life without any excesses. OK fine. But that isn't the case for millions of people - and I'm 'poor' but still have excesses. And it's not a case of generalising - as stats are just that - but taking figures that represent what people (on average) do - as in https://www.magnet.co.uk/advice-inspiration/blog/2018/February/food-waste-around-the-world/.
So it's amazing how people talk the talk but really don't walk the walk. I personally have around 3 acres of land that cannot grown crops, 2 acres are too wet for machinery in spring and autumn. and the last acre is an old gravel pit so steep sides and thin soil. These are the places animals should go.There is also a more than slightly inconvenient issue with plant proteins in the north, namely we need a good summer to get beans mature enough to dry. the only one that does grow is peas.. Pease pudding anyone? Hot or cold new or old.. your choice.
