(Update: McKinsey seems to have pulled the whole issue from the web, which is too bad because there was a lot of good stuff in it.  The text of my contribution can be found below.)

I have a short essay in a special edition of the McKinsey Quarterly, What Matters.  My piece is waaaay back at the end of the printed volume, and all the preceding articles are well worth a look.  Other essayists include Steven Chu, Hal Varian, Nicholas Stern, Kim Stanley Robinson, Yochai Benkler, Vinod Khosla, Arianna Huffington, Joseph Nye, and many more.  Good company.

Here is the essay: "The New Biofactories" (PDF), Robert Carlson, What Matters, McKinsey & Company, 2009.
