How to be a vegetarian? (And also, why to be one?)

[Whateverist]

So, after becoming aware of a number of facts over the last few years, and most recently learning that animal husbandry causes more environmental damage than all of the planes trains and automobiles TOGETHER (and checking that fact, and finding it to be true), my family has decided, as a group, that we are going to be vegetarians.

This isn't a huge leap, because we have slowly been reducing meat in our diets lately, but eliminating it entirely is still a big step to take.

We have 3 main reasons for doing this.  The Pros:
1. It is what is best for the health of the earth.
2. It is what is best for the health of ourselves.
3. It is what is best for the health of the animals in question.
4. I want my kid to have a future, for there to be a rainforest, fresh air and water, seas filled with life and not dead zones and plastic islands.  I want my kids kids kids kids, and so forth, to have the same.

The Cons:
1. No bacon

1.  That is by far the best and least contestable reason.
2.  That is highly debatable and I would take the other side personally.
3.  Well yeah, being dead is practically synonymous with the very poorest state of health.
4.  I only wish that could be achieved through vegetarianism.  I'd become a vegetarian or kill myself if I thought that was true.

No bacon?  Hell I already have no bacon in my life on account of my damned new years resolution.  Gradually, I am becoming light on my feet though.
