Advantages and disadvantages: Endangered Animals

Most zoos are not only great places to get close to wildlife, many are also doing their part to bolster dwindling populations of animals still living free in the wild. Anyway, I think zoos are not entirely beneficial for endangered animals.

Zoos are very important in animals that are on the verge of extinction. In addition, injured or orphaned animals (in danger of dying in the wild) need rehabilitation before being reintroduced into the wild. Secondly, we should have zoos to protect endangered animals. This is because a zoo is the only sure fire way to be sure that they are not being poached. In fact, some zoos are very good about providing sufficient living and roaming space for their inhabitants. These types of zoos should make an effort to house endangered animals.

On the other hand, zoos are great for people that enjoy looking at animals. However, it's true they're not the best option for protecting endangered animals. Animals need room to roam that's similar to their natural habitat. Also, putting endangered animals in zoos to protect them is not going to save them in the long run, it just protects the lost specimens until they die.

So the question are: Are good places the zoos for endangered animals? What do you think about this?
Should animals stay in natural enclosures or in zoos?
