Chúng ta có thể mong đợi cùng một động vật - họ sẽ được hưởng lợi từ một mối quan hệ gần gũi với thiên nhiên? Rõ ràng họ không xuất hiện để sử dụng nghệ thuật để miêu tả bất kỳ cảm xúc tích cực về bản chất, mặc dù đôi khi công trình xây dựng của họ, chẳng hạn như tổ của một con chim Bower, miêu tả một cảm giác trật tự và gọi một cảm giác tự hỏi rằng chúng tôi có thể nghiêng để tin rằng nó là nghệ thuật | 32 2 Mankind s Relationship to Animals in Nature Can we expect the same of animals - would they benefit from a close relationship with nature Clearly they do not appear to use art to portray any positive feelings about nature although sometimes their constructions such as the nest of a bower bird portray a sense of order and invoke a feeling of wonder that may incline us to believe that it is art. In contrast to this the activities of the elephants that are persuaded to daub paint on canvases which are sold to tourists in Asia are not art but merely the performance of a reward-driven behaviour. Even though they don t usually portray their feelings through the sort of art that we know and understand we have reason to expect that animals derive similar benefit from a close connection to nature. As well as us animals are likely to benefit from being able to identify the natural features of the environment and return to safe places at times of danger find food sources more readily and obtain shelter when needed. If a latent need to be close to nature is present in humans and animals it is likely that both derive mental satisfaction from a more natural environment - a need that may be partially satisfied if the enrichment in a cage is natural rather than artificial. There have been a few experiments designed to test this hypothesis. One such was an attempt to discover whether rabbits a natural grazing animal prefer to eat grass or whether they would be satisfied with an artificial food mix that is commonly offered to caged rabbits Leslie et al. 2004 . The rabbits showed no clear preference for grass although this could be explained because the mix could be eaten faster and most prey animals like to consume their food as quickly as possible so that they can retreat to safety. Other students in my group were unable to demonstrate any benefit of or serious interest in natural enrichment foliage and tree branches for gliders Greer 2006 or the scents of favourite plants for
