Yes, certainly these are good reasons to become a vegetarian.

It is a bit difficult initially because old habits die hard. I myself found it very tempting whenever some of my family members would eat right in front of me but as the time passed i got used to it & now i don't feel like eating meat at all not even eggs.

About the cons -

1. If you are determined you can stop eating meat. Think of the pain & agony all the animals would be going through before they reach your plate.

Is it worth eating a food which has reached you in such a way ?

2. It is not that expensive that it will make you broke. There are variety of recipes available on the net. http://www.vegcooking.com/

3. The choices may be limited but there are variety of restaurants that are vegetarian only. Also suggest the restaurant owners to have special menus for vegetarians as vegetarianism is in vogue.

4. If someone invites you to dinner get them informed indirectly that you are a vegetarian or unintentionally show them veg dishes - http://www.vegcooking.com
