Are or zoos cruel to wild animals? Opinion

I don't agree with zoos, because I doesn't seem as though his philosophy is becoming a cruelty.

First I think that the zoos are cruel to wild animals, because I think that an animal must be free. 

I believe that all animals don't receive suitable conditions.

I think it's an economic benefit to the zoo a beneficial tourism and I believe the state has to put restraint.

To sum up, I am very concernid and very envolved in animal rights and I am pessimistic about the future of the animals.
