Yes, public parks are very important in cities. They give people a place to relax and have fun. Parks also help improve air quality by providing green spaces. People can go there to jog, walk, or play sports, which is good for their health. Parks also serve as places where people can meet and socialize, making the city more beautiful and improving mental well-being by offering a break from the busy urban life.

I don't think public parks are always necessary. Maintaining them can be very expensive for the city. The space used for parks could be better used for building houses or commercial buildings. Not everyone uses parks, so the money spent on them might be better used elsewhere. In some places, parks can become unsafe or not well-maintained, making them less useful. Some people might prefer indoor places like gyms or malls for recreation.

Whether public parks are necessary depends on the city. In big cities with lots of people, parks are very important because they provide open spaces. In smaller towns, there might already be natural areas that offer the same benefits. The local climate also affects how much people use parks. The decision to build parks should be based on what the community needs and wants.
