Actress Malaika Arora has teamed up with animal rights organisation PETA India to star in a new campaign, calling for an end to horse-drawn carriage rides.The print advertisement for the People for the Ethical Treatment of Animals (PETA) features Malaika standing with a horse. The accompanying words read: "Compassion Is Beautiful -- Say No to Horse-Drawn Carriage Rides".Talking about it, she said in a statement: "I'm adding my voice to PETA's campaign to ask kind people everywhere to think again before supporting an industry that subjects intelligent horses to slavery.""By choosing other forms of transportation, everyone has the power to spare horses the misery of being forced to work past the point of exhaustion."PETA India has documented the abuse horses endure in Mumbai, and was an intervener in a Bombay High Court case which resulted in the directive that horse carriages be phased out of Mumbai within a year.In April, however, the Supreme Court allowed for horse-drawn carriages to ply for the following six months or until a review petition is finally decided by the Bombay High Court, whichever comes first.
