I took a trip to Las Vegas, NV with my most recent and favorite employer. Las Vegas is a city that most people "need" to go to at least once in their lives, but I never felt this way. Beside the gambling, sex, drugs and rock & roll, Las Vegas represents mostly bad qualities to me such as waste and useless consumption. Since I am very happily married, and I'd never gamble (because I subscribe to probabilities), Las Vegas is somewhere that I would have never gone if my awesome employer wasn't footing the bill.
As long as there are low prices for the things that harm the environment the most, there will be little incentive for any agricultural industries to make any moves such as these. In my opinion, the incentive should be provided by the government (sadly, with some of our tax dollars).
Government programs have recently made some big steps in the right direction. I estimated that the "Cash for Clunkers" program removes between 5,700,000,000 and 4,950,000,000 pounds of CO2 per year. I've heard of a new program that is supposed to do the same thing for inefficient appliances.
The American diet is driven largely by the price of our food choices. Unfortunately for meat lovers, this will have an effect on their wallets -- very much like recent tobacco taxes, making the price for a pack of cigarettes double over the last few years.
I guess that I've been a little bit inspired recently. I've watched a bunch of videos on YouTube that I should have seen a long time ago. They are videos that look at the global warming discussion from a risk management perspective. Greg Craven is a physics teacher, but he has made quite a few professional videos that are all on YouTube. The one that you have to see is called How It All Ends (embedded below). He reminds me a little bit of Bill Nye or Alton Brown (of the Food Network).
