"Affair is The Life of Survival"

I feel a bit funny when I read the board says Affair Is The Life of Survival' in front of the Gorilla's cage. Then, my friend can guess what I am thinking about, he just mentioned not to put the analogy to the human and then I smile. I have a small discussion after that, about why they put that board. Some of species in the zoo can not survive for long period with many reasons, so there is usually a species survival plan (SSP) for that kind of animal such as a love affair between a male/female between 'A' Zoo with 'B'Zoo. Gorilla is one of this program. In the last decade, the Lincoln park zoo have been successfully of doing the SSP.

I imagine, this case is not happening in Indonesia, where so many Gorillas or Tigers still living in the jungle of Sumatra. I remember, when we went for fishing in the forest of Sumatra, then my father remind us that tiger can appear at any time, so just be careful. Or even in Bukit Lawang Sumatra 'Orang Utan' lives with their species in the natural forest and a part from that, there is a trekking area with water fall for the tourist.
