Animal Testing

Animal testing or animal research is the use of non-human animals in scientific experimentation. It is estimated that 50 to 100 million vertebrate animals worldwide — from zebrafish to non-human primates — are used annually. Most animals are euthanized after being used in an experiment. Researchs are usually conducted inside universities, medical schools, pharmaceutical companies, farms, defense establishments, and commercial facilities that provide animal-testing services to industry. These experiments are usually tested on animals first than humans, this is to prevent any serious damage against human.
