bacon causes cancer! WHO!

They are not held in "appalling conditions" in a first world country such as Australia. The very suggestion is not only completely ignorant, but deeply offensive to many people. Breaches of animal welfare are treated very seriously.

WOW! Maybe in your alternative universe world but here animals are caged all their life in super farms where the idea is to have as much animals on less area of ground. Just last year Chris Christie vetoed pig crate ban and that is just tip of the iceberg how horribly animals are mistreated. Or chickens that are bread with such large breasts that they can't even walk because of the weight and lots of them drop dead before they get slaughtered. In fact animals are kept in such appalling conditions sometimes are sources of cow madness, swine flu, E. Coli and many more.

Really I'm not pulling those things out of my ass, but rather from reality, like for instance, this documentary which shows how animal farming conditions are worse every day and animals change, they're not even same as they were couple of decades ago, let alone stone age.

Nutrients found only in meat include B12, Vitamin D

Again maybe in your alternative universe but we here make our own vitamin D in our bodies when the skin is exposed to the Sun and also I said I was vegetarian I don't take soy proteins but whey proteins and get B12 from milk and cheese.

Vitamin A is most aboundand in potatoes, carrots, kale... and not meat. Similar with calcium that is also present in many vegetables, fruits.

And additional problem is that people eat meat every day for every meal, they don't even know how to eat other food.

The majority of the world's plant species are either poisonous to us, or inedible. While there are plenty of "wild" meats we have to chose from, and only a handful of domesticated species (like pig and cattle), the vast majority of plant foods we consume are artificially-selected and domesticated. This includes: Wheat, Maize, Rice, Banana, Tomato, Cornflour, Broccoli, Orange, Apple, Pear, Lemon, Figs, etc. It includes the vast majority of plant foods. If your argument is that you want to avoid domesticated foods then you have far more plant foods you'll need to avoid compared to animal foods.

I don't want to avoid domesticated foods, only avoid eating domesticated animals. WHO also says that people who eat meat eat 2 to 3 times more sugar and fat then their body needs.

How does cancer happens by meat?
Meat is devoid of fiber and other nutrients that have a protective effect. Meat also contains animal protein, saturated fat, and, in some cases, carcinogenic compounds such as heterocyclic amines (HCA) and polycyclic aromatic hydrocarbons (PAH) formed during the processing or cooking of meat. HCAs, formed as meat is cooked at high temperatures, and PAHs, formed during the burning of organic substances, are believed to increase cancer risk. In addition, the high fat content of meat and other animal products increases hormone production, thus increasing the risk of hormone-related cancers such as breast and prostate cancer.

And for the end watch this documentary on pig farming that is so appalling causing danger and death not only for those that eat them, but those that work on those shameful farms and live many miles around it. - Really educate yourself people.
