Greg, Liz, and Tom talk with Peggy Cunniff, Executive Director of the National Anti-Vivisection Society. She tells us how she became involved in the anti-vivisection movement, and explains why the definition of "vivisection" has evolved over time. She also explains how human tissue cultures can eventually eliminate the need to test experimental medical treatments on animals prior to human testing, and how technological advances are creating cruelty-free alternatives to animal testing.
