Another example of the 'Invisible Green Hand
' at work. This time in the dairy industry. See link from Science Daily here
"The study shows that the carbon footprint for a gallon of milk produced in 2007 was only 37 percent of that produced in 1944. Improved efficiency has enabled the U.S. dairy industry to produce 186 billion pounds of milk from 9.2 million cows in 2007, compared to only 117 billion pounds of milk from 25.6 million cows in 1944. This has resulted in a 41 percent decrease in the total carbon footprint for U.S. milk production."
This is just one more example why we really may not need climate change legislation.Left on its own, the market is producing the incentives and the technology necessary for increasing output while utilizing fewer resources ( and reducing emissions).
The current Markey-Waxman ( Cap and Trade) legislation, narrowly passed in congress, in theory is supposed to put a price on carbon and provide the incentives that will encourage more such innovation. But in reality, it has become so overloaded with regulations that it will not be effective at either harnessing market forces or reducing emissions.

A better approach for dealing with climate change or any environmental problem is to develop resilient market based economies that are able to invest in the technology necessary to adapt to ever changing resource constraints. We know that this works, becuase we see it everyday in the agriculture industry through better management and technology.
