New studies of social behaviour of giraffes have brought also new questions regarding the social relationships of this apparently well-known species.

The diploma thesis focused on ZOOs in relation to animal rights and environmental context. Zoological Gardens in Olomouc and Brno were chosen and compared, specifically giraffes breeding. A comparative method and the SWOT analysis were used in the thesis. Another part of the study was a questionnaire survey. The aim was to evaluate the usefulness of the ZOOs. The results showed that ZOOs are not in concordance with the philosophy and principles of the environmental ethics and animal rights, however, they contribute positively to a sustenance of selected species and thus to their biodiversity and develop ecological mindset of visitors.
