I believe that all animals should be provided with Five Basic Freedoms. They are, Freedom of thirst, hunger, and malnutrition, Freedom from fear and distress, Freedom from pain, injury, and disease, Freedom to behave as they would in the wild, and Freedom to have warmth and "physical comfort".
I am against Zoos because I feel that they do not meet these basic freedoms.
These are the reasons why I am against Zoos.
Poor animals are trained and forced to perform. This cannot be good for the animal; this is not how they would act in the wild. They would not be riding bikes, jumping through flaming hoops, or balancing balls on their noses.
Some animals can die from changes in their lifestyle. This could happen if they were moved to a Zoo. That cannot be good for the Zoo. Especially the animals, because animals really on other animals. If that animal dies what will the other one do? For example, a Rhino relies on a bird that lives in the same habitat. This bird stands on the Rhino's back all day; it eats the bugs that could bite the Rhino. What would the bird do if the Rhino died from a change in lifestyle? It would have no food.
Animals need large enclosures. If the animal does not have enough room, it can not get any exercise and stay healthy.
Another example, a jaguar needs a lot of room because they are able to run really, really, fast. They are used to getting to do that in the wild. If they are put in an enclosure, before the animal can kick it up to full speed, the jaguar will probably crash into a barrier. Which could lead to brain damage.
You could say Zoos are greedy. They spend little money on the animal enclosures, and then spend the rest on things they think are more important. Think about the animals. The five freedoms are already provided in the wild. You shouldn't take it all away.
