My first trip to the zoo was years before during an elementary school field trip. It is an activity I still remembered to this day. It was for the first time that I had found me so close to animals like tigers and lions. I would say that the trip was worth every minute of time spending. However, some feel that animals should not be kept in cages, and should rather be let out in the wild. They think keeping animal in cages shows the cruel of human beings. As far as I concerned, without zoos, many of us would never have the chance to see how a tiger or lion really looks like.
