The horse-drawn carriages that clip clop around Central Park could be banned under City Council legislation to be introduced at the urging of animal advocates who say the horses are treated inhumanely. Councilman Tony Avella, who plans to introduce the bill next Wednesday Dec. 12, 2007, said the horses that have entertained tourists and New Yorkers for decades are exposed to cruel conditions and are at risk of injury or death as they weave through city traffic.
