YOUR correspondent Des Morgan (letters 14 May) needs to look at the main problem with meat eating and not get himself tied into knots over religious controversy about methods of slaughter.

We live in a world of rising population and major food shortages. The rising consumption of meat is unsustainable. A kilo of meat needs at least 8 kilos of grain to produce. Instead of feeding grain to cattle and poultry, but using it directly in our diet, feeding the world adequately will be possible.
