What are the positive and negative aspects of a zoo or safari park?

Answers

In my opinion, the only advantage is that endangered species will be given thechance to reproduce and their numbers will increase. Apart from that, I disagreewith any animals being caged or kept in even a very large fenced area. However,it doesn't take a genius to realise that there are people (poachers) out therethat will do anything to kill off these precious animals for money, endangered or not.

Positive: You get to see different animals, see all kinds of habitats, learn new facts about all the animals and see them maybe in action!

Negative: They might be sleeping, In a cage or fence so they can't get out, restricted.
