It's not realistic that you'll recognize every ingredient in every bite of food you eat. And that would take the fun out of eating. On the other hand, it is responsible to ask the questions about the origins of your food. Then you can make educated decisions about the food ecosystem that you support.
I won't know all the answers, I don't know if I'll know many to start. I'm hoping that is what will make this fun, educational, and worthwhile for everyone's participation.
