The production of all animal products unavoidable causes animal suffering, be it through forced impregnation of animals to breed further descendants, be it due to cramped and unhygienic conditions in factory farming, be it finally in the slaughterhouse. Animals want to live, in freedom and dignity, with their family and friends, just as we want to. They do not want to be considered our property and exploited by us. They do not want to die prematurely and cruelly in a slaughterhouse.
Not least, humans suffer as well from the animal industry, for example as poorly paid slaughterhouse workers who have no other job opportunities and therefore have to perform the ungrateful, gruesome and mentally destructive work of killing animals for our consumption. In addition to that, a significant part of our global crop harvest is fed to animals while hundreds of millions of humans live in hunger.
In today's society, where we have access to a both secure and incredibly varied production of food, we are no longer dependent on exploiting animals to survive. We can cover our nutrient requirements completely through a balanced plant diet. Thanks to newest culinary innovations, we can also enjoy the same dishes and flavours as before, just produced from plants. We are therefore convicted that a vegan way of living is, from an animal ethics perspective, the morally correct one.
The production of animal source foods is very inefficient, both in regards to requirements for animal feed and usage of space. Depending on species, obtaining one calorie of meat requires 4 to 12 calories of plant food to be fed to an animal. Therefore, an omnivore nutrition uses significantly more arable land and water per person than a vegan one does. Despite the production of animal source foods taking up around 70% of all arable land globally, it only yields about 20% of all globally consumed calories. The amazon rainforest deforestation happens to a majority for the animal industry: In addition to freeing ground for grazing areas, soy is farmed there, which is mostly used in the production of animal feed, not for human consumption. Not lastly, the methane emissions of cows are problematic, as methane is a very strong greenhouse gas. The animal industry causes about as many greenhouse gas emissions as the entire transport industry, which is all cars, trucks, trains, ships and planes added up.
A purely vegan nutrition is possible without problems today. Renowned nutritional institutes like the Academy of Nutrition and Dietetics (formerly American Dietetic Association) confirm that a well-planned vegetarian or vegan diet is possible in every stage of life and can even carry health benefits. Evidence suggests that a vegan nutrition reduces the risk for several types of medical conditions that mostly occur in industrialized countries, including heart diseases, obesity, diabetes and different types of cancer.
