Advantages of Animal Testing in Medical Research
Medical research involving animals has dramatically improved the health of
the human race. Without animal testing， the cure for polio would not exist and
diabetics would suffer or die from their disease. Despite these benefits， some
people believe that animals should be not be used for testing medical techniques
and drugs. This essay will outline the advantages of animal testing.
Animal testing allows scientists to test and create new drugs. Animals such
as monkeys or rabbits have similar physical processes to humans. This allows
scientists to test the effects of certain drugs. If a drug produces adverse
effects in animals it is probably unfit for human use.
Animal testing is cheap. There is a large supply of animals for medical
research. Animals are easily bred， and maintained safely in controlled labs. The
costs of testing in humans would be extremely high.
Many people argue that animal testing is cruel. In some cases this is true.
However it would be much more cruel to test new drugs on people or children， or
to let people die because there was not enough information about a drug.
Furthermore， legislation in most countries sets standards for animal treatment，
and laboratories have guidelines to prevent cruelty.
Opponents of animal research also say that information from animals does
not apply to humans. They point to certain commercial drugs which have been
withdrawn because of side-effects in humans While it is true that animal systems
differ from human systems， there are enough similarities to apply information
from animals to humans.
Animal rights campaigners claim that we don't need new tests because we
already have vast amounts of information. However， many new deadly infections
appear every year and new treatments and drugs are needed to combat these deadly
plagues.
Animal testing is needed in the world we live in. Our responsibility is to
manage the animals in our care and balance their suffering against the good that
comes from them.
