I love animals, and I hate the thought of animals being killed inhumanely. These scumbags in the third world countries that not only kill, but torture animals don't deserve to live themselves. People in Korea torture animals when they kill them, due to the fact that they believe the more adrenaline the animal is experiencing at the time of death, the tastier the meat is. These are the areas of livestock produce that need to be stopped. These pathetic people should starve to death and torture each other for a feed, we don't need them.
On the other hand though, you pretend to know about the meat industry in Australia, which you evidently don't. You claim that livestock here have a bad life, I assure you any grain fed steer that has access to shelter is a happy animal. They get the best medical treatment, preventative care and eat better than you "vegiewhatsies". The end of the line for them is understandably upsetting for some (even me), but the animal doesn't know it's about to be knocked on the head.
Vegetarians take iron supplements, without these you'd have to eat meat. So in a world not as advanced as ours, you'd have no choice.
The talk of greens feeding the world is all well and good, but if that's the case why isn't subsistence farming in the 3rd world countries working? The farmers sell their produce for little cash, but why wouldn't they just eat it instead?
Please don't take this as a go at you, the "rant" was just a joke, because I couldn't be bothered multiquoting. Wanting to be a voice for the animals is very noble, and when I see the ads on TV about animal welfare, they hit home with me a lot more than the ads of the poor people. I have much more compassion for animals than humans.
