Book excerpt: Heritage is a social construction rooted in modern and contemporary societies. It is commonly a positive assessment of many elements of the physical and human environment (e.g. ecosystems and landscapes, monuments, customs, gender norms, religious practices, gastronomy, and livelihoods). Heritage and tourism are strongly related to each other in that heritage gives rise to tourist attractions and activities, and tourism enhances the designation of heritage sites. A post-humanist perspective the moral valuation of equality between humans and other animals demands that both are sentient beings and self-aware of their pain and pleasure. Thus, the involvement of animals as heritage elements by themselves or as an element of tourist consumption in heritage sites implies their commodification and lack of agency. As such, these practices are usually unethical, since they threaten the animals' primary interests: not to suffer, not to feel pain and to be able to live their freedom. This book contains chapters that reveal both the unethical interactions between humans and animals within heritage tourism, and those that show experiences in which efforts are made to minimize damage within the commercialization of animals involved as heritage themselves.
