Every year in Canada more than 25 million animals are slaughtered for human consumption. The companies that manufacture and kill these animals for food represent a multibillion-dollar industry, which requires 2500 gallons of water just to produce one pound of meat. Also a single pig factory generates raw waste equal to that of a city of 12,000 people. Finally eating animal products is bad for human health because it leads directly to many diseases and illnesses such as, heart attack, stroke, cancer, and osteoporosis. For these reasons individuals should live their lives without consuming anything that comes from animals. .
To begin, animals that are produced for human consumption live their entire lives as machines. For example male cows and pigs are castrated without painkillers. Also when many of the chicken livestock are being bread, they spend their entire lives inside cages that are too small for them, so they are not able to spread their wings, or even turn around. Factory farmers do this because they want the chickens, cows, pigs, and all other animals to spend all of their energy on producing eggs, milk, and flesh. Once the company decides the animal is ready for it to be turned into a product for human consumption it then is shipped off to the slaughterhouse. When being shipped to the slaughterhouse "the only law regarding transit to slaughter refers to transport by train, although 95 percent of the animals are moved by truck, where they are subjected to weather extremes, overcrowding, hunger, and thirst."" (http://www.cowsarecool.com/animals.html). The entire purpose of a slaughterhouse is to produce the most meat, milk, and eggs using the least amount of space, time, and money. For these reasons, slaughterhouses do not use any humane treatment on animals at all. Once the animals arrive at the slaughterhouse they endure mutilation, for example cows are dehorned and branded, without any sort of anesthesia.
