I saw a picture on that facebook yesterday that had a caption on it saying that vegetarians 'save 100 animals a year'.
Now this got me thinking...
If everyone gave up eating meat then there would be a surplus of animals, and if remained unchecked would rapidly lead to there being 100's times the number of 'food animals' than humans. This gives a problem as these animals will need feeding. They will no doubt then eat all the vegetable, grain, pulse, etc foods that are grown leaving none for the humans.
Assuming we find a way out of this (probably by holding a massive 'day off barbecue' for everyone), then we will find oursleves not breeding the 'food animals', and thereby the vegetarianists will not be saving any animals. I dare say an established vegie isn't saving any animals already, 'cos they aren't eating an animal that hasn't been bread because they wouldn't be buying it anyway.
Anyway, I was tempted to reply to the faceplant post asking the poster where in their small 4th floor flat they were going to keep their 10 cows, 10 sheep and 80 chickens, but really couldn't be bothered. I may get round to winding them up later though.
Anyway, to keep things naturally balanced.....
...Bacon sarnie anyone?
