That animal consumption has an environmental impact means that it should 
be taxed so as to make the long term costs immediate.  It's a similar 
principle to paying a recycling deposit on cans and bottles.

That animal consumption costs a lot of resources is by no means a reason 
not to consume animals [1].  The price of meat reflects those costs. 
Unless the government is subsidizing it which is a very bad idea in terms 
of social efficiency [2].

Perhaps a less extreme solution than becoming vegan is to make a pact to 
pay the true cost of the animal products you consume.  For every serving 
of animal, donate $X to an appropriate charity.  Erica and Rob, I nominate 
you two to estimate a lower bound on X, including government farm 
subsidies and environmental impact, but excluding health factors and 
animal suffering (since we're looking for a lower bound and the latter 
are less easily quantifiable).


Footnotes:

[1] Erica, Rob, Karen, Dave, Julie, and other veg(etari)ans on 
improvetheworld can chime in with many other reasons not to eat animals.

[2] For the same reason it's a bad idea for an airline to use your airfare 
to serve you a meal on a plane -- you eat it even if the cost of producing 
it far exceeds your utility for eating it, as long as your utility is 
positive.  (Those who don't grok the notion of sunk cost may even eat if 
their utility is *negative* because "Hey, I paid for it; I better eat 
it".)
