I haven't seen this movie yet, but I'd like to. It's an important topic. If you have an opportunity to watch it, please do. Emily recently watched it and posted about it. From what I've read and seen so far, the basic message is that we can all influence the food industry by the choices we make. Buy from your local farms and farmer's markets when you can. Plant a garden. When you shop at the grocery store, try to buy in season produce and organic when you can. It's more expensive, but it's worth it.
I'll admit that I could do better. I do try to buy primarily organic products when they're available, but I still often buy vegetables and fruits shipped from thousands of miles away. I go meatless several days a week, but I do still eat meat and don't always buy organic. I try to buy products without high-fructose corn syrup (my god it's in everything!), but there are a few things I haven't found good alternatives for (my horseradish for example, oddly enough, and I can be tempted by a good sale on ice cream, cereal bars, etc.). I can do better. And I'm sure you can too. So let's educate ourselves and identify a few ways we can influence the food industry for the better. All-natural food is healthier and tastes better, and it should really be what we all demand.
