Disclaimer: In some places and some times, one cannot help but eat meat to survive!
Medically, everyone agrees that Non Vegetarian Diet is not good, and increases Cholesterol, increased Toxins, triggers Inflammation Response, and even cause serious diseases like Mad Cow, Swine Flu, Chickungunya, Brain Diseases, and Kuru (Neurological Disorder) - among-st many Prion Diseases. We will go deeper into it.
Environmentally, it takes more Land, Water and Resources to produce Meat. It keeps the harm or foot print of one's living minimal on the Environment.
Economically, it is cheaper to feed the World and eliminate Hunger, if everyone shuns Meat based diet.
Morally and Ethically it does not make sense to kill anyone - and larger Animals and Animals closer to our DNA. Call it Relative Principle, otherwise Prion listed diseases are there. It is a principle of "Do untu others as one wants others do to unto onself" If you are willing to be someone's food, then it is OK.
Yogic Science have been blessed with Scientific Researches over 25 years, if one want to Realize Buddha Hood, Siddi, or Permanent Happiness, or Contentedness, one has to follow the Character Building Blocks of Yama and Niyama. Can one be happy by Hating, being Angry, Lying, Killing and so on?
More Scientific points:
1. Humans do not have canines like Carnivorous. They have at max 4 Canines, and some do not have. So they are 4/32 Percentage wise Carnivorous.
2. Humans do not have jaws or bite-strength like Carnivorous.
3. Humans have long Alimentary Canals and Canines have short ones. Food starts rotting when not part of the main body which keeps it alive. In the Food Chain, or Entropy Scales. Non Veg Tissues would rot faster than the Vegetable Tissues as they habe Higher Metabolic Decomposition. The rotten food makes toxins. That means Humans eating Meats would have more toxins in their canal for more longer time. It makes a double whammy for plant eater eating meat.
4. Life is about RNA/DNA Computing Machinery. It has been found that Cows when fed their own meat or meat of other mammals, developed Mad Cow Diseases. Same thing with Chickens and Pigs and even Human Beings!
5. It seems Red Meat will trigger Inflammation Response and cause Carcinoma risk.
6. When an Animal is killed, it is under stress, and produces a lot of toxins called Cortisols Steriods, which can also trigger Inflmmatory Response and Auto Immune Disorders. Think if you are under constant Stress and Flight and Fight Response, what happens to your Body and Auto Immune Response. There are 450 Auto Immune Issues, including Cancer and Tumor, and the main culprit is Environmental, Chemical, Emotional, etc. Stress.
In defense of Eating Vegetables, as some claim they have Life and Pain too. Most plants drop of fruits, flowers, seeds, for consumption. We should eat parts of Plants and Trees that are dropped or plants that have died.
