One pillar of vegan propaganda is that vast areas of farmland are used to produce grain that is fed to animals. This grain should be fed to humans.
Firstly as a Paleo sympathiser I avoid grains wherever possible. I dabble in sourdough bread etc but only as a very minor part of my diet. Grains are basically anti-nutrients and should be consumed with caution. That's why sourdough is good as it removes the phytic acids that make normal grain products harmful.
Secondly the vegans totally miss the point that rangelands and pasture lands are not able to be farmed for vegetables or grains. This was the mistake made in the USA who opened up prairie lands to smallholder farmers who ploughed up vast areas of prairie for agriculture leading to the dustbowl in the 1930s. Today states such as Oklahoma and Arkansas (the original dust bowl, read Steinbeck) only sustain agriculture through a poisonous mix of pesticides and herbicides, artificial fertilisers, irrigation and now GM varieties. According to Nat Geo most of the American Mid West farmland is in danger of collapse in our lifetimes.
Thus rangelands and pasture lands are an ideal global resource for producing the planet's most widely eaten meat - goat - as well as sheep and grass fed cattle, deer, roo and other delectable morsels.
Take free range meats out of the market and the planet would starve within a year.
I avoid factory or feedlot raised meat, and only purchase free range eggs.. locally if possible. I'm in a great position here as I have access to excellent free range everything in the Manning Valley, but people in capital cities have an even better access to this produce due to the proliferation of farmers markets and online suppliers, if they choose to get off their arses and make a choice. A good example is Bangalow Free Range pork, I can't get it here as it all goes to the capitals.
Now for some lovely lard.. I'll check with Mr Butcher re the pig fat, thanks for the leads.
