Why shouldn't I eat fast food?
user
Well, I can give you one example of why I think that's a bad idea.  You eat fast food because it's easy and convenient.  It tastes good.  And it's really bad for you, your body, and the environment.

One other reason is that it's not very healthy.  It will damage your body, and the food industry uses a lot of chemicals.
assistant
Great, what else can you tell me?
user
Okay, one more reason.  Eating fast food is really bad for the environment.
assistant
You did mention that.

But I mean it's just gross.  The cattle, chickens, and fish are so tortured.  The beef comes from cows which have been fed all kinds of disgusting stuff.
