When I read Dr. Polya's backgrounder at MWC I see a reflection of myself. My age, my white hair, a caucasian aussie (I'm a scot)and, like me, someone concerned with humanity and the state of the earth. However, he has worked four decades as a biochemist and is now trying his hand at journalism. That's my career. I have some advice for Dr. Polya: a little knowledge is a dangerous thing. There is a counter-argument to every issue you raise. A good journalist will present both (sometimes many) sides. That often involves disagreeing with your own biases. This is a skill too few achieve. Here's an exercise to help you. Identify the opposite view to the one you hold and gather evidence to prove it's right and that you are wrong.  
This will help you achieve the credibility which you so painfully lack (except among the disenchanted) and may refine your personal biochemistry. Thanks for reading.
