I was reading about collective ownership in Wikipedia and came upon a sentence. Please read this sentence and tell me why a comma is used here:
Examples of collective ownership include modern forms of corporate ownership as well as producer cooperatives, which are in contrast to forms of common ownership, such as a public park available to everyone.
I understand that a public park is an example of common ownership, is the use of a comma necessary here?
Thanks in advance.
