People for the Ethical Treatment of Animals sent letters to several U.S. politicians Monday urging them to cut funding for the National Institutes of Health, an organization that funds animal research at many universities across the country, including the University of Wisconsin-Madison. In the letters, PETA condemns UW-Madison among other universities ? including Columbia University and the University of California-San Francisco ? for conducting ?costly? research studies which ?do nothing to advance human health? when the money could be spent on ?safe? research.
