Human being does not need to eat meat in order to maintain good health because they can get all their food needs from meatless products and meatless substitute. Do you agree or disagree?
    Meat provides human beings with a lot of nutrition needed for maintaining good health. People get protein, fat, heat and cholesterol etc. from meat to build themselves stronger than ever.
    However, along with the development of meatless products and meatless substitute, people can also get their nutrition needs.
    Vegetarians are the best example. They don’t eat meat, but only depend on vegetables, eggs and milk. They live a happy life, working every day, doing sports, going for disco and traveling for sightseeing, etc. Most of them are in such good health; they can even compete with athletes in sports games. Monks are another example. Due to their faithful religious belief, they are not allowed to eat any meat, yet they are in good shape. Moreover, the secret of longevity is to eat meat as little as possible, according to most of people over 100 years old. Theoretically, people will be in good health so long as they have enough protein and vitamin. People can easily get protein from milk and egg, while get vitamin from fruits and vegetables. Science and technology makes everything possible.
    Based on the above, my conclusion is that people can live without meat, particularly along with the advancement of the science and technology, which can create more meatless substitutes. People can maintain good health, even if they do not eat any meat.
