Protesters fighting to save Lake Urmia in Iran from permanent environmental damage have not given up . On May 21, 2012, once again people in Urmia and several other cities in the Azerbaijan region of Iran have called on the government to save the dying Lake Urmia , one of the world's largest salt water lakes. In Khoy (photo above) protesters hung a banner on a bridge  saying “the death of Lake Urmia is the death of Azerbaijan.” One blogger published a cartoon saying  “Let's save Lake Urmia with our tears.”
Here are a couple of videos shared by Iranian citizens of demonstrations in Urmia.
