Acharya Prashant addresses the argument that Vitamin B12 can only be obtained from animal meat. He clarifies that no animal, including humans, specifically produces Vitamin B12 in its body. Instead, Vitamin B12 is produced by a bacterium that is found in the intestines of many animals, including humans, and is also present in the soil. The reason humans often do not get enough B12 is that the bacteria in our intestines produce it too low down for it to be absorbed, and it is excreted with waste. In nature, animals consume B12 by eating unwashed plants and fruits that have fine soil particles on them. However, modern human practices have disrupted this natural process. Firstly, the overuse of chemicals and fertilizers has made the soil lifeless, killing the B12-producing bacteria. Secondly, due to our civilized habits, we thoroughly wash our food, removing any traces of soil. He refutes the idea that nature intends for humans to eat meat for B12, stating that it is human actions that have broken the natural cycle of obtaining it from soil on plants. He points out the hypocrisy in people who reject artificial B12 supplements while readily accepting other artificial medicines and vaccines for their own health. This shows that the objection is not about what is natural, but about self-interest. When their own life is at stake, they accept artificial intervention, but to save an animal's life, they are unwilling to take a simple B12 supplement. He advises taking vegan B12 supplements, which are readily available, and to check the labels to ensure they are not animal-derived. Acharya Prashant then addresses another argument that essential amino acids are only found in meat. He explains that out of 20 amino acids, the human body produces 11. The remaining nine essential amino acids are found in both animal meat and plants. The notion that they are exclusive to meat is a delusion, as animals themselves get these amino acids from plants. He also tackles the misconception that if the entire world's population of 8 billion people became vegetarian, there would not be enough land to feed everyone. He states that this is a completely erroneous and misleading argument. In fact, the opposite is true. A non-vegetarian's diet consumes 17 times more land, 14 times more water, and 10 times more energy than a vegetarian's. This is because over three-quarters of the world's agricultural land is used to grow food for livestock, not directly for humans. He concludes by stating that if humans stopped eating meat, the vast amount of land currently used for livestock would become available. Even if half of that land were used for human agriculture, there would be ample food for everyone. The world's food shortages and malnutrition are, in fact, primarily caused by meat-eaters, whose diet is extremely resource-intensive. He further links meat consumption to fatal diseases like heart disease, cancer, and diabetes, stating that 8.1 million deaths could be prevented annually if people adopted a vegan diet. He also identifies the meat and dairy industries as the biggest contributors to climate change. Therefore, the only sustainable way forward for the planet is for humanity to adopt a vegetarian or vegan diet.
