When you make an urban park, you have to accept two things though. First, locally the city becomes more expensive. And second, it will occupy more space over potentially natural zones (over suburban area actually, that themselves will grow over peri-rural, that will push these, etc.)

If your goal is wildlife preservation or carbon capture, you probably want one more hectare in a forest rather than an hectare in a park inside a city.

Don't get me wrong, I wanted more trees when I was living in a city. But the choice is between livable big cities or trying to make the cities as small impact as possible.
