The five main reasons why some people decide to follow a vegetarian lifestyle:
People who eat plenty of fruit and vegetables, pulses – all types of peas, beans and lentils, and wholegrains (oats, wholemeal bread, wholegrain spaghetti, brown rice etc) but little animal fat and animal protein cut their risk of many illnesses and diseases including some of the most common cancers, heart disease, strokes, obesity and diabetes.
55 billion animals are killed ever year for meat production; nearly one billion of these are slaughtered in the UK. Most of the animals raised for meat production in the UK are factory farmed, the most intensively reared being pigs, chickens, ducks and turkeys..
More than 70 per cent of all agricultural land in Britain is used to feed animals because of animal farming's inefficiency. It can take as much as 17kg of vegetable protein to produce 1kg of meat protein.

Throughout history, some relgions have required their followers to observe strict dietary guidlines, including avoiding some meat and animal products. A short explanation about what each religion teaches about eating animals as food.
