In fact, we all live in big cities very often without thinking about ecology. We always walk the streets and squares where it is always very dusty from passing cars. Also we will affect zoos, because children often ask their parents to take them there. This is my personal opinion, but I think that zoos should be closed. There are five important reasons for this: 1. Mockery of animals. 2. Conservation of wild nature. 3. Development of diseases. 4. Danger to humans in the event that the animal escapes. 5. Wild animals should not sit in cages as they will lose their instincts
