Calling them 'green spaces' is a bit of a stretch. For one, most golf ranges are privately owned, meaning that visitors have to be members. Second, the effort to keep the lawn regulation height means constant--and I mean constant--maintenance by a small army of groundskeepers.

A public green space should be: publicly accessible, free of flying hazards and motor vehicles, accessible for wheelchair and stroller use, and useable for community events free of charge.

I'm surprised no one's mentioned the volume of agricultural weedkiller and fertilizer that golf courses go through. It doesn't look like an environmental disaster, but it certainly is.
