Today people hope that animal testing will help find new methods for incurable diseases in the future.) All these examples support the fact that with the help of animal testing today people live healthier and have greater opportunities to survive than in the past. So this is one of the most significant advantages of animal experiments. It's why people support...... middle of paper...... Np, July 5, 2010. Web. February 23, 2014."“Alternatives?"."
