Vegetarianism is the practice of not consuming the flesh of any animal (including sea animals) with or without also eschewing other animal derivatives, such as dairy products or eggs. Some vegetarians also choose to refrain from wearing clothing that has involved the death of animals, such as leather, silk and fur. Veganism excludes all animal products from diet and in some definitions from attire also, whether or not the production of clothing or items has involved the actual death of an animal (dairy, eggs, honey, wool, silk, down feathers, etc.). Vegetarians have varied motivations including religious, cultural, ethical, environmental, social, economic, health, political, and personal concerns.
