One of the most important things to me when I first became a homeowner in 1979 was to have a vegetable garden, because I wanted my kids to see where food came from, that it came from the soil, and it came from compost - in my case, it came from healthy soil, water sunshine - and that you could have a role in that in tending the earth and growing food. I've been very, very happy with my backyard garden now since 1979. Otherwise, kids don't really understand where food comes from. They think it comes from the supermarket. It can come from there, but ultimately it comes from someone gardening, someone farming. My kids have always been very attracted to that, they're grown people now. I have a 34 year old son who gave me some wonderful grand kids, they all garden. I have a 35 year old daughter, she's out in the garden with me every day, and my 13 year old daughter, who's out in the garden with me often. So it's important, I think, for everybody of every age to know where we get our real wealth. It's from our soil, it's from healthy soil and water, clean water and sunshine. And also our seeds, we have to protect our heritage seeds. There's a lot of new seeds that have genetically modified organisms in them, GMOs or what-have-you and I'm really drawn to the heirloom seeds, the old seeds that have served us well as a civilization over thousands of years, to protect those old seeds, to save them and keep planting and showing our young people where food comes from.
