There is no requirement to be a vegan or even a vegetarian. America would do well if people would:
* Give up swine and shellfish
* Give up Fast food/takeout
* Give up imported foods (who knows what's imported today, but much is, it isn't labeled)
* Cut back on meat, say having 2 or 3 meatless days a week
* Cut back on the amount of meat -- smaller serving sizes
* Eat only Free Range / Organic foods
* Give up the ballpark meats, social eating in general (the Masonic or Fireman's chicken barbecue, the clambakes, Pig Roasts, etc.)
* Start with any of the above
