They do it out of the consciousness, that many foods could be used better and more expediently without being wasted on livestock. Ecological reasons are not only linked to economy but also to the ethical point of view and thus our circle of the motives closes. That is to say, everything coheres. As I have said already there is still a reason worth mentioning, and that is, of course, the fashionable one. Vegetarianism of which there was nothing to be heard of for years is relatively new and for that reason has become at once very attractive.
People hope to get a slender figure and to preserve a youthful appearance.
The future will show who of these new born vegetarians will hold out. However I did not want to say, that one must be a vegetarian from birth. The human being is an immeasurably complicated being. In his subconscious there are stored knowledge and experiences of many thousands of generations. Only crucial knowledge and experiences are dominating.
