The so called sand dunes or Ram Bridge extends over 30,000 meters from India to Srilanka. There are over 20 similar sand dunes accross the world. For the sethu project, They just need 300 meters to be excavated out of 30,000 meters. The monkey Advani is trying to get political gains over this issue and all poisonous cross belts are supporting him. I am a hindu and from a place close to the so called Ram bridge. 99% of the people here feel that the project should go ahead and our fishermen and srilankan fishermen used to shit on the sand dunes for hundreds of years. If you feel it is holy, then take it.
