Each year, more than 100 million animals—more than three each second—are bred, injected, infected, cut open, genetically altered, force-fed drugs and chemicals in the name of science and testing.
Compassionate Innovation
When animal experimentation first began some 200 years ago, our scientific knowledge was very limited. Today, science is more sophisticated––we’ve mapped the human genome, grown tissues in culture and modeled human physiology using computers. By comparison animal testing looks like a crude relic of history. HSI is leading the campaign to bring scientific research and testing into the 21st century. Help us by taking action online and becoming a compassionate shopper.
