April 24 in the calendar of environmental dates is marked as World Day for Laboratory Animals, which was established by the International Association against Painful Experiments on Animals (InterNICH) in 1979 and supported by the UN.
Initially, it was “celebrated” by animal protection organizations in a number of countries, and today a movement against vivisection (experiments and experiments on laboratory animals) is actively developing around the world, which is supported by activists from various public and animal protection organizations.
It must be said that animals have been used in experiments since ancient times, but nevertheless these works were of an episodic nature. The concept of "laboratory animal" was formed at the end of the 19th century in connection with the rapid development of experimental biology and medicine, and since the second half of the 20th century, the method of scientific experimentation on animals took shape as an independent direction. Today, laboratory animals are used to model pathological processes and test medicines, cosmetics, cigarettes, food additives, household chemicals... The main customers of research are large pharmaceutical and cosmetic corporations.
