Yesterday I listened, via Zoom, to a most interesting lecture by an economics professor on how to take account of climate change in accounting. This was part of my University of the Third Age in Cambridge (U3AC) lectures.
One of the "take away" remarks was that he thought we would be able to feed the world as long as we eat less meat. In my view, we will be persuaded by adverts to enjoy alternatives, if only on certain days each week. Beef and lamb need huge amounts of land and water. If we don't change, we will all die!
As a carnivore who enjoys steaks I shall not find this totally easy. Eating less lamb and beef and more pork and chicken are good starters. Personally, I could be a vegetarian despite enjoying my steaks, certainly on some days a week.
My 10 year old granddaughter has been vegan for over a year and some of her food has been really tasty.
