The 50 cent Burger you have at McDonald's really costs $200 Burger

Heard an interview on the radio and read about the author Jonathan Safran Foer, that just released a book called "Eating Animals" http://www.progressivereader.com/?p=59606 where he claims that meat industry is the number on cost of global warming. He also states that the very cheap burgers we eat, see above, have such an immense carbon footprint that it really cost 200 dollars. I had a similar experience a few weeks ago when I bought 4 t-shirts at HM for 200 SEK, which is the same amount that I payed for a t-shirt in the local market in Koh Lanta. I guess it's true what they say, nothing is for free!
