The first reason zoos should be banned is because of the fact that malnutrition, mistreatment, and murder (the three m's) is becoming more and more popular in zoos worldwide. From China to Detroit, animals are not being treated the way animals should be treated. In fact, some animals are not even getting a chance at life. In 2007, the IDA (In Defense of Animals) came out with a top ten list of the worst places for an elephant to go. All ten of the American zoos have had elephants die prematurely there. This is because of mistreatment of animals (improper diet, lack of exercise, unsuitable living conditions, etc.).
