Which is more effective for reducing greenhouse gases?

Question

Eating locally (within 100 miles)

or

Eating vegan

Answer 1

why not eat a vegan organic diet within 100 miles?

If you eat vegan, but get most of your food from central and south america, that would probably create more greenhouse gasses than eating an omnivourous local diet.

Either way, reducing food miles, pesticides and hooved meat are all great goals.

Answer 2

Eating locally grown foods can also be vegan :-)

Meat is not a huge threat to the environment (except for all that gas that the cows have and all of the diseased waste that washes into the surrounding environment).  Meat is mostly just gross and poorly treated when it is alive.

Locally grown veggies are the best choice.

Answer 3

Eating locally or preferably at home would cause less water vapor and carbon dioxide to be emitted by you and whoever you go to dinner with.

Water vapor is 97% of the greenhouse layer and CO2 is only 0.3%.  There's no evidence that CO2 has any effect on global warming, so why worry about emitting these gases anyway?

Answer 4

Eating foods that have been genetically modified to need less fertiliser is even better.

Answer 5

Neither will have a measurable effect on global warming because they both involving moving carbon in a continuous loop from atmosphere to food to human and back to the atmosphere.

COOKING food has a bigger effect depending on whether you use a conventional fossil fuel / electric oven and stove versus an inherently more efficient microwave oven.
