I do love my meat but I do try to mix up my meals and go vegetarian or pescetarian 2 or 3 days a week. Many of my meaty meals come from laziness - that is picking up a sandwich from the supermarket instead of preparing something fresh.
I wonder how much the increasing popularity of convenience meals has driven up meat consumption, if at all. I find veggie meals even more convenient and they are often quick and simple.
There's plenty of choice in veggie food everywhere these days, so I don't think there's any excuse to not try it. I don't think it does people good to eat too much meat anyway.
