Animal experiment is the base of American research and treatment of disease Each year,17 million to 22 million animals are sacrificed in the name of science While 90 percent of them are rats and mice.180,000 dogs, 50,000 cats,61,000 monkeys and 554, 000 rabbits are done away with in laboratories operated by industry and government(26)But the public has raised a protest over these deaths.They’ve documented cases in winch monkeys were isolated in steel tanks for 45 days and dogs were bombed with radiation or chemicals Scientists say such incidents are rare. Laws have been passed to govern testing.Many research centers now have committees to review all animal experiments,and computers can be used in place of animals in many experiments.(27) But scientists say they can’t do without animals to test new drugs and treatments on animals to make sure they’re safe for humans.Animal experiments produced treatments for diseases Animal rights activists have shown they will go to almost any length.One New York researcher received more than 10.000 protest letters following Publicity of her experiments in which she gave drugs to monkeys.The battle between scientists and activists raises a basic question:Can modern society be both humane in its treatment of living things and advanced in its treatment of disease? (28)It seems certain there will be new restrictions placed on the use of animals in scientific experiments.
