This week we get green as we welcome John DeCicco, Ph. D, an environmentalist who is a senior lecturer at the University of Michigan. We'll be asking Mr. DeCicco how the oil disaster in the Gulf of Mexico will affect our consumption of petroleum--if at all. And, what does he think of alternative fuels like ethanol and electricity? You might just be surprised at the answer. Of course, we'll also get into the news of the week including the wind down of the Mercury brand. Plus, May sales numbers are in and there are some interesting results including the fact that Chrysler seems to be gaining on Honda. John McElroy's in studio with Peter De Lorenzo, the Autoextremist, and David Welch from Bloomberg BusinessWeek.
