GROW GARDENS, NOT LAWNS is awesome! I've been trying to convert my lot for the past few years. Books on permaculture and homesteading are great for this. Here are a couple resources if anyone cares:
Amazon.com: Gaia's Garden, Second Edition: A Guide To Home-Scale Permaculture (9781603580298): Toby Hemenway: Books
The Backyard Homestead: Produce all the food you need on just a quarter acre!: Carleen Madigan: 9781603421386: Amazon.com: Books
Anyhow, I'm not positive that organic tastes better than non-organic. What I do know for certain is fresh from my garden or a farmers market tastes a helluva lot better than anything off the supermarket shelf.
So I think organic and non-GMO are great for a variety of reasons, but freshness is paramount for taste.
