Considering all the negative effects on nature, climate, resources, world-hunger and animals that have been mentioned here one will automatically wonder why mankind does not simply live on a purely vegan diet
In the US, there are about 16 million vegans and vegetarians at the moment with an upward trend. But most people do not regard a completely plant based diet as a possible alternative. Yet, this attitude is primarily based on prejudice and false information, which makes many people believe that a vegan diet is deficient and means abstention. This is due to decades of manipulation through the advertisements of the animal industry, which wants to make us believe that animal products are important for a well-balanced diet.
On the other hand, we know that advertising aims at presenting products in the most favourable light and that it uses extreme exaggeration.
And politics, too, supports the milk and meat lobbies wherever it is possible. In the EU alone more than 50 billion euros of subventions are paid to the agro-industry, a large part of which goes to the animal industry. http://www.provegan.info/eng/vegan/the-healthiest-diet/
It is obvious that dealing with animal products contributes immensely to economic growth.
Another issue that makes a vegan diet appear in a negative light is the official recommendations on our diet. These are made by diet commissions which are largely composed of representatives of the animal industry. In Switzerland they did not even make an effort to hide this fact: until recently the head of the meat industry's marketing department (whose aim is to promote the sales of meat) was a member of the Swiss diet commission, the highest authority to give official advice on diets in Switzerland, which also serves as consultant of the government. http://www.provegan.info/eng/vegan/the-healthiest-diet/page-2/
In other countries like Germany this connection is not less evident either. The Ministry of Food and Agriculture is the highest authority in matters of diet standards. The Minister's task also consists in promoting agriculture, thus the animal industry. How come these controversial functions are combined in one person? One could equally create a combined Ministry of Health and the tobacco industry. The Minister, Christian Schmidt, is a professing "flexitarian", who showed that he accepts the exaggerated consumption of animal products and consequently the mass killing of animals and the damage done to the environment when he spoke out against a vegan diet. How do such people, who do not even have a sound education in matters of diet, dare to pass judgment?
Minister Schmidt's statement even made it into BILD, the leading German tabloid. For often subjects which cast a bad light on veganism are blown up.
This was also the case when a small child died in 2004 allegedly as a result of a vegan diet. But it was hidden in the report that the child did not eat anything at all because of a serious pneumonia. Moreover its parents were followers of the so-called Paleo Diet, which is far from being a balanced vegan diet. That report was published in the context of "veganism is dangerous" and was intentionally distorted in order to support the animal industry. http://www.provegan.info/eng/vegan/the-healthiest-diet/page-3/
Dr Henrich, the author of the ProVegan brochure, calls this principle "worldwide legal manipulation". For the diet commissions who issue diet recommendations are often composed of dietetic scientists, doctors, lobbyists and marketing experts who are paid by the meat, milk, fish and eggs industries. The pharmaceutical industry has no interest in a vegan diet either for they can make not profit with healthy people. It is hard to understand that money is the most important interest of so many humans.
So the gullible citizen is influenced in a way that he decides against a healthy, purely vegetal diet and in favour of a meat and milk-based diet.
The following paragraph Studies will show that a diet based on animal products is absolutely unhealthy.
Apart from that, we all know of the scandals in the animal industry, which are revealed in regular intervals. In spite of it all, the responsible persons try to play down things and to sweep them under the carpet. Yet, in a purely vegetal diet, you will find none of the following:
