This leads me of course to at least mention here the cruel methods used in the slaughtering of animals and fowls for human consumption. The creatures are treated as if they possessed no feeling or consciousness of their own - and such attitudes show a most unfortunate misreading of natural events. As a direct result, at least as many diseases develop through such procedures as would exist in a highly primitive society with unsanitary conditions.
