Are our zoos cruel to wild animals? Discuss

There are a lot of zoos now days, it makes people interesting, especially little kids. Animals should live on the field not in the small metal room, they have their own freedom, just as we do, so I think that our zoos are cruel to wild animals because they have their own freedom, they won't stress out if they live on the field, families should live together, so they won't miss each other because they have emotion...etc
Just as people do have their own freedom, the animals should have their own freedom, place to live, what kind of person wants to be in a jail for a long time, all the people have their dream house, or place that they like to live in, but look at zoo, those animals don't. Animals should be so stressful that they want a resistance against humans, they will have bad memory of humans, which is not great. What happens if people are so stressful, or want their freedom? People would be a rebel, and violent. For example, there is a book called 1984, in this book, the party controls the people, they want no want to have their own privacy, fun, happiness because the party wants their absolute power, an order to keep their power, they forced people to have no relationship, sex...etc. Anyways, the animals should have their freedom to live enjoyable lives, just as humans don't want to be being watched.
Most people live with their family, so as animals. They have feelings of their father, mother, son, daughter, brother, or sister, animals are very similar to humans. Because their similar, we shouldn't make the zoo, first of all, they are going to miss their family, if the animals that are in the zoo are young, they would be really embarrassing of people who are watching, which will make them to feel stressful.
If we want to keep the animals happily, we should do something good for them, but people don't, they mostly want to get money. Imagine the world with we are in zoo, and animals are ruling, that is going to be very bad, they are just going to eat us as food, hurt us, mostly do something bad. However we just flip that imagination over, we are doing bad things to animals, and animals are feeling bad because of us.
It is good to see the animals, but I do no think people want to watch, forlorn, or gloomy animals in the zoo, as people have fun in the zoo, the animals should have a fun too because they are very similar to us, they have their own emotions, families, act...etc. I think people will glad to see the animals that are happy.
