Setusamundram project is neither ecologically desirable nor economically viable. Vijay can you tell us which ship will use this route. naval chief has already said that this narrow chanel won't help much to security purpose. Go and see national Geographic to see the size of ships commissioned by international business. This channel at best will ferry small boats from calcutt to nagpattnam. And the two are linked by road. Advise Tamil nadu government to develope nagapattnam Port. There is absolutely no need to disturb Ram Setu.
