The world does produce enough to feed its inhabitants – in fact we waste vast quantities of grain and soybeans by feeding them to animals, getting back from the animals only a small fraction of the nutritional value of the plant foods we put into them.

Pacifists have usually regarded the use of violence as absolutely wrong, irrespective of its consequences. This, like other ‘no matter what’ prohibitions, assumes the validity of the distinction between acts and omissions.
