What are the arguments for and against vegetarianism?

Seeing animals running around filled with cuteness can bring a smile to anybody's face. But knowing the fact that most of them will be taken away and butchered creates a number of arguments because some people would simply put this down as cruelty were as others would call it 'meat.'

Many vegetarians, and especially vegans, also choose to give up the use of all animal products, including leather, fur, and animal products used in common household items and substances. Some say that killing animals for any reason is entirely unnecessary, while others argue that human beings are not meant to be carnivores at all, pointing to a human's small canines, flat molars, long intestines and less acidic stomachs, all ideal for eating fruits (carnivores have larger teeth, shorter intestines and stronger stomach acids.) Many feel that all animals are creatures with emotions, feelings, and the ability to feel pain too.
