I am looking at different subjects that could be put under...zoo keeping. I have thought of noise and people, for example, King's cross station where there are a lot of people and often times there is always a rush. Also I have thought about the library at uni and the amount of noise and people that are sometimes not under control, whether walking up and down or being loud, a combination of both or just taking up too much space.
I wanted to look at pregnant lady's for this, not because I see the baby as an animal but because when the baby is a few months old, it starts to move around and kick and you woman is not necessarily able to control it.
I looked at children. The above images are taken from google as an example.
