Animal trafficking has been gaining momentum in Brazil and, as a result of this crime, it has become one of the main causes of threats to animals, endangered species and biodiversity. The illegal trade in these animals is the third largest trafficking, behind only arms and drug trafficking, with exorbitant numbers of animals exploited, with approximately 38 million animals being removed from Brazil each year. It is estimated that for every 10 animals stolen from their natural habitat, 9 do not survive due to the precarious conditions they are subjected to during transportation, which is one of the main reasons for the threat to biodiversity. Since this is a crime that produces several negative effects and occurs mostly to satisfy human desires, stricter laws need to be regulated to reduce this crime, considering that in addition to the low routine imposed, sometimes the penalty is not properly applied, leaving the crime unpunished so that the act continues and more animals become victims of this situation. The topic of animal trafficking involves several fields, going beyond the possible loss of biodiversity, such as violation of animal welfare, ecology, law, biology, public health, mistreatment, ethics, among others, thus offering a possible opportunity for comprehensive and multidisciplinary research, enriching academic knowledge and bringing more visibility to the subject. The study of this topic contributes to the understanding and awareness about environmental protection, in addition to affecting not only ecosystems, but also social, economic and public health consequences. In view of the facts mentioned, investigating this problem can help identify solutions to mitigate its negative impacts on society.
