Pulque, the alcoholic beverage of pre-Columbian highland Mesoamerica is the fermented derivative of aguamiel, the juice or sap of the agave known as agave pulquero—principally Agave salmiana. Aguamiel is a sweet, somewhat heavy juice that collects in a scraped out basin in the heart of the agave pulquero and, unless refrigerated, rapidly ferments into the alcoholic pulque. The agents of fermentation are ambient and plant-colonizing bacteria and yeasts. Fresh pulque is a frothy, cloudy brew with a slightly sour taste, usually containing around 2 percent alcohol or somewhat higher, meaning it can be drunk in large quantities without intoxicating the imbiber. Although it is a nutritious drink, consumption was condemned by Spaniards in varying degrees during the Colonial Period. Its popularity in contemporary southern Mexico is increasing after more than a century of persecution and public disparagement. Pulque figures prominently in pre- and post-Columbian Mesoamerican history. Production of tequila and mezcal is completely different from production of pulque. The former are distilled from the pressed juice (tepache) of macerated and roasted hearts of certain agaves. The juice is fermented in vats for several days, then heated in a still, evaporated, and condensed. Tequila, by law is made from A. tequilana, and mezcal by custom is made primarily from A. angustifolia. Both these distillates contain about 40 percent alcohol. Pulque is a naturally occurring product consumed by native peoples for at least two millennia. Tequila and mezcal are industrial products derived from processes introduced into the Americas by Europeans.

Modern zoos emerged as mass entertainment, spaces of public leisure and of culture. In the past, they served as monuments and expressions of the degree of “civilization” and progress of a city and its respective country. In Latin America, zoos date from the last quarter of the 19th century. The history of Latin American zoos is a political, cultural, and social history. The conditions of their creation and operation over the decades have conferred important specificities to these institutions. Since their inception, zoos in Latin America have reflected nationalistic aspirations, civilizational projects, and social transformation. Over the decades, the history of many zoos has blended with natural history in Latin America, as many zoo founders were important scientists. The development of new sensitivities toward animals also follows the history of zoos in Latin America from the beginning, because the first animal protection societies appeared at the same time. Today, zoos face vigorous claims from animal rights activists calling for their closure. In view of so many challenges, these institutions are reinventing themselves with an increased focus on conservation and environmental education, joining international zoological societies with high standards of quality. Among several of these societies, the Latin American Association of Zoological Parks and Aquariums (ALPZA) stands out. Founded in 1990, ALPZA organizes, reshapes, and integrates Latin American zoos, establishing global connections. Various actors play a role in the defense and contestation of zoos, such as politicians, scientists, conservationists, animal protection societies, anti-zoo activists, visitors, administrators, officials, and, of course, thousands of wild animals from all over the world who have lived in Latin American cities for decades.
