Protesting in the national capital for over a month, Tamil Nadu farmers on Saturday drank their own urine to draw the Centre's attention to the drought in their state and other demands.On Friday, they had collected their urine in plastic bottles and threatened to consume it if the Union government fails to respond to their demands, including a loan waiver, drought relief package and formation of a Cauvery river management board.From wearing human skulls to conducting mock funerals and even stripping at Raisina Hill here, the farmers have been grabbing eyeballs for the last 40 days with their novel ways of protest. A few days ago, these farmers met Union Minister Pon Radhakrishnan who hails from Tamil Nadu. However, the two sides failed to reach a consensus on their demands.
