This is it: retail giants make the ethical choices they make not (just) because they believe in it; it happens when the customer makes those choices for himself. They aren't going to stock their shelves with organic yogurt and locally grown produce and grass-fed beef for the sole purpose of standing behind what they believe in; they make these choices because the customer himself makes a personal choice, demands the product, and contributes to the profit.
It's up to us to make change happen. Visit a farmer's market today, pick your own peaches, grow a basil plant on your kitchen ledge, spend that extra hour indulging in a home-cooked dinner instead of heating up a microwaveable one, know where your food comes from, choose organic and local and from-scratch rather than processed when you can and if your pocket allows.
Preachy EV! But still, give it a shot with me :)
