Throughout history humans have used non-human animals in many different ways to ensure the success of their survival and throughout history there have been differing opinions about how and when animals should be used for satisfying human needs. Some argue that we should no longer use animals in ways that seem to exploit them. Others argue this is okay as long as the animals aren't hurt. Students can explore the different issues of animal rights and animal welfare in this four-volume set written at the fourth and fifth grade reading levels. Copyright (C) Muze Inc. 2005.
