The ideology produced through the historical oppression of animals has been defined as speciesism —discrimination based on the specie— and under its cover different forms of violence which have broad social support have been legitimized. Activities such as livestock, fishing or hunting, among many others, are an inherent part of our society and have fostered the development of industries where animals suffer systematic and programmed exploitation.
Starting in the 1960s, after a series of historical precedents, the critical voices towards the use of animals as resources began to resonate with greater force and maturity than in previous periods. In 1963, the Hunting Saboteurs Association was formed. With it began a new stage marked by direct action in which there were massive raids in laboratories, undercover investigations, liberations of animals and sabotage against mink farms, slaughterhouses and other infrastructures. At the same moment, essays such as Animal Machines (Harrison, 1964) and, later, Animal Liberation (Singer, 1975), provided a growing number of people concerned about animals with tools to understand and combat their exploitation. All this ended up laying the foundations of the Animal Liberation movement. Since then, countless projects have been developed throughout much of the international geography aiming at dismantling the mechanisms and structures that legitimize and produce the exploitation of animals.
Tras los Muros is a project which is close to the values of antispeciesism. Through reports and graphic investigations that portray both animal exploitation an animal rights activism, it offers useful information for the analysis of speciesism and its consequences.
It is not an organization, but a personal photography project in pursuit of Animal Liberation.
