I just read an item on the internet about how bunny rabbits are eating the insulation from wires in cars parked in the Denver International Airport parking lot. This is said to be because the electrical insulation in the "newer" cars is made of a soy bean material and the bunnies just love it. I'm wondering if one of you out there might be able tell tell us what year they started using edible insulation, and how many years it will take to get us to understand the value of engineered plastics. You know, stuff that's not good to eat.
