Hard to beleive somebody actually used up good money for a study like this. It would make far more economic sense to ban all gas burning cars and replace them with clean emission vehicles. The knowledge to build these cars have been around for decades...they are just not built because nobody wants to loose the 'easy money' of current cars, not to mention the tax on gas.
But to use this study for our advantage...the 'footprint' of a large snake would be far less than even the food they eat. One rodent every 2-4 weeks is nothing compared to what other animals of similar size/weight would eat.
