Dear, Mr. Bala Krishnan, marine life and ecology will be impacted in whatever manner you disturb the bridge. Anyway, don't tell me MK & co and Indian govt are worried about the ecology. Whether the bridge is imaginary or not the expected financial benefits are definitely imaginary. It is being compared to Suez or Panama canal by the proponents. There couldn't be a more ridiculous argument. MK is more concerned about this as hurting Hindu sentiments (no matter whether you believe in Ram or not) will fetch him minority votes by solidifying his 'secular' character.
