Basically, I really admire how you managed to answer the question. That's the kind of explanation I like to get when someone is talking about his or her attitude towards vegetarians and vegans. But there are just two things that I think should also be taken under consideration while thinking about eating animals.

1. 50% of air pollution comes from food industry. So, if you decide to become a vegetarian or, even better, vegan, you actually help the environment get better. Showing "not eating meat" and "not eating carrots that don't come from ecological farming" as two different things is an omission. Eating meat is, in general, bad for the planet (and so is eating dairy products, of course). But eating non-eco vegetables and fruits is bad for it, too. It's the same thing. I know people that became vegan only for ecological reasons.

2. "Locally grown is often better than long transportations" - yes, because long transportation means wasting more fuel, and this is not a good thing. But that sentence is only partially true. The fact that we live in Europe and not on the other side of the globe does not mean that there is no slavery involved in the food production in here. Local products you buy in the nearest store may also come from slavery work. Check this out: http://www.globalslaveryindex.org/ - I live in Europe and the number of people enslaved in my country, as they say there, is pretty high. It's actually higher than in Brasil, China and a few of African countries. Slavery is not only a problem in Africa or Asia. It's a different type of slavery, but still counts.

Please excuse my poor English, I haven't been writing in this language for over a year now and it got a little bit rusty. :)
