You have a box of strawberries in front of you. You can see and smell the fresh, organic strawberries. You can take a knife and slice through the strawberries and they look as delicious as before. Now you have a pig in front of you. You either think that that pig is a cute, cuddly, and playful animal or you see bacon, ham, sausage, pork, or a hot dog. Either people will see an animal, or they will see food. However, most wouldn’t be willing to take a butcher’s knife and cut through a living pig. Similarly, some people eat dogs in China but Americans could never imagine hurting a dog. What is the distinction between these two animals? Why would it be wrong to kill a dog but right to kill a pig or vice-versa? It all comes down to the culture in which one is raised. In American culture, dogs are considered as pets and our companions, while pigs are food. In other cultures, dogs are food and pigs are considered as pets. In some parts of India, the cow is a sacred animal, and certain Hindus wouldn’t dare to consume its meat. Many meat-eaters believe that consuming dairy and animal meat is the way humans are designed. However, because of the certain cultural beliefs people have, diet is learned behavior. Regardless of culture, everyone is a human being. The question it all boils down to is: what diet is natural to the human species? Veganism, the abstinence of consuming animals and animal products, is the most sustainable lifestyle because it is the most natural and healthy way of human existence and is also environmentally and socially conservative. The term “vegan” was first coined in 1944 by Donald Watson when he founded the Vegan Society in England. It was initially defined as a “non-dairy vegetarian,” but then evolved into a more animal rights centered definition as “the doctrine that man should live without exploiting animals.” People normally think that veganism is only a diet that requires abstention from all animal food, such as land animal meat, seafood, dairy, eggs, honey, and gelatin. However, veganism is a lifestyle the branches to the abstention of all animal products as well: wool, fur, silk, suede, leather, etc. Vegans live off a plant-based diet that includes vegetables, fruits, nuts, grains, and the array of dishes that can be produced with combinations of these ingredients. With the rise of vegan versions of familiar foods: vegan hot dogs, ice cream, cheese, meat substitutes, non-dairy yogurt, and even vegan pizza, it is becoming easier for meat eaters to change diets. Interest in veganism increased in the 2010s, when more vegan stores opened and vegan options became increasingly available in supermarkets and restaurants. Due to the diet’s growing popularity among celebrities, veganism is becoming trendy among millennials worldwide.People may go vegan because of health benefits, animal rights, or both. Vegan diets are known to contain less saturated fat and a higher content of many essential nutrients like fiber, vitamins C, vitamin E, and magnesium. Vegans are usually healthier and are in less of a risk of developing certain cancers, diabetes, high blood pressure and suffering from arthritis (Lin). Sustainability is also a key point: the environmental benefits are considerable, such as the more efficient use of land and water or the reduction of greenhouse gas emissions and global hunger. However, even many vegans don’t realize that their diet is the most biologically natural diet for humans. Humans do not require animal products to survive; humans’ mouths do not salivate at the sight of a living pig as would a wolf, and many studies prove that our physiology itself is not suited for meat consumption.
