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. Our responsibility is to manage the animals in our care and balance their suffering against the good that comes from them.
Animals are easily bred, and maintained safely in controlled labs. 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.
The costs of testing in humans would be extremely high. Furthermore, legislation in most countries sets standards for animal treatment, and laboratories have guidelines to prevent cruelty.
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. There is a large supply of animals for medical research.
The short life cycle of the animals allow researchers to study the animals throughout their entire life cycle and through several generations in a short amount of time.
Researchers also have control over the animal's environment (temperature, diet, light, ventilation, etc.) to make sure the animals are kept healthy and experimental variables are kept to a minimum.
