Wendy Warren suggests that because vegetarians eat eggs and dairy produce they don't care about animal welfare (Mailbox April 3). What nonsense!

Her assumption that there will be an "adjustment" to the world population is an extraordinary statement. Is she suggesting we wait for a cataclysm to solve the world food problem?

Vegetarianism is often a stage prior to becoming vegan. Both diets provide sufficient protein and all necessary nutrients for good health as well as using far less of the world's resources. What evidence does she have to support her claim that most veggies don't eat soya?

The teeth, jaws, mouth and digestive system of humans have far more in common with those of herbivores than carnivores. Ms Warren's arguments are unconvincing, ill-informed and concerned only with finding fault.

I do not criticise meat-eaters. I pass on information to enable people to make educated choices.

Ms Warren says she would continue to eat meat "by sheer cussedness". If current trends continue, future generations may not have that choice. She should be grateful to vegetarians and vegans, as their abstinence from meat will allow meat-eating to continue for longer!
