It's interesting reading the comments that are from a US perspective, where there are vast amounts of untamed land for wildlife and recreation. Many US commenters are highlighting that they would rather that cities be cities, because there is already plenty of green space outside cities. In the UK, most land is either farmland, or built on, so urban green areas are much more important for wildlife. There is a drive in the UK to create more "green corridors" linking green areas together, but this is facing stiff competition with the drive to develop second cities. Ripping up parking lots (car parks) and planting trees would be even more important in the UK.
