Discuss which is the most important thing that will help people to live a long and healthy life in the cities of the future.

In the cities of the future, there are many things that can help people to live a long and healthy life. However, access to green spaces and parks is arguably the most important. Green spaces can provide people with a place to exercise, relax, and enjoy nature, which can all contribute to improved mental and physical health. They can also help to mitigate the negative effects of pollution and noise, which are common in urban environments. Additionally, green spaces can promote social interaction and community cohesion, which can have positive effects on mental health. Therefore, it is important for future cities to prioritize the creation and maintenance of green spaces and parks to promote the health and well-being of their residents.
