I worked on an educational farm for five years and that was the usual answer I got even while standing in the middle of a garden with the class!! Unfortunately, the parents in the group knew little more than their children. I try not to get to depressed about it, since as you said, more and more people are growing their own food. It's better to laugh at their ignorance. For instance did you know that male and female dairy cows give milk?
I am excited about the future. I really am. There are schools here in Tucson which are creating gardens for the kids. And they LOVE it! I was the guest speaker at a kid's club meeting at the church where I work. They could not get enough of learning about how to grow things. We planted a tree and they are SO proud of it. As am I. I am going to do my part and get as many members of the younger generations excited about plants, gardens and educating them about the beauty of growing your own food.
I thank you kindly for your reply. I appreciate it. Now, here I go about to show my own ignorance, no, I did NOT know that male and femle dariy cows gave milk. I am one that believed only the females were the ones responsible. I learned something new today! Thank you!
