Don’t Choke Ed

Played like classic Hangman (or Wheel of Fortune), you have to fill in the blanks by guessing letters. If you guess correctly, the letters fill in the appropriate blanks. If you guess incorrectly, the cloud of pollution hanging over Ed's head threatens to engulf him. Guess too many wrong letters and you lose - and poor Ed suffers the consequences. Hint: all the words are somehow related to air pollution and transportation.
