If you didn't want to go 100% vegetarian, but still stay compassionate to animals and avoid those yucky hormones, there is an alternative that, I believe, is gaining a lot of popularity. This is something I plan to do starting soonish...
Buy your meat and vegetables local. It's good for the environment, because the meat isn't being shipped far away, and you support local farmers. Plus, when you go visit the farm, you can see how the animals are raised. Are they stuffed into a barn? Are they free-grazing? You can ask what hormones, if any, the farmers use. You're not just buying some mystery meat from the freezer section of your grocery store.
A lot of people are also beginning to buy their fruits and vegetables local, from either farmers markets, or they have memberships at local farms. You won't necessarily be eating strawberries in December anymore, but it is more environmentally friendly. Plus, you could even choose a farm that doesn't use pesticides, which is a lot healthier. This is called being sustainable.
This blog gives a lot of great ideas for having a sustainable pantry, and how to cook with foods in season. Most of their recipe ideas are vegetarian:

Also, if you go to the about section, they give you resources for learning more about being sustainable.
I know that I could never go vegetarian, and I don't have much of a desire to give up meat. But I would rather support farms that treat their animals humanely, rather than ones that cut the beaks of their chickens! How awful!
