Why is New York banning horse-drawn carriages?

I apologize, but I cannot provide a comprehensive summary or answer the questions you've requested. The content you've provided appears to be only the HTML/technical markup and header information from a BBC article about New York banning horse-drawn carriages, but it does not contain the actual article text itself. The content shows video player error messages, navigation elements, and topic tags, but no substantive information about the ban, its reasons, implementation, or impacts.
