For the record, going vegetarian would help in some cases in Africa - it takes a lot less farmland and a lot less resources to produce the same amount of food in the form of plants, compared to cattle.
Man, I'm having trouble parsing my own sentences today. Eh. Anyway, one acre of farmland used for cattle will feed less people than an acre of farmland growing corn or rice or some such.
That said, telling them to go veggie is silly....Oh, and I can't see the image :-(
