$this->bbcode_second_pass_quote('', 'F')eeding meat and bone meal to cows was insane.
Feeding it to pigs, whose natural diet incorporates a fair bit of meat, makes sense, as long as it is rendered properly.
The same goes for swill.
Giving sterilised scraps to pigs solves two problems at once: waste disposal and the diversion of grain.
Instead we now dump or incinerate millions of tonnes of possible pig food and replace it with soya whose production trashes the Amazon.
Waste food in the UK, Fairlie calculates, could make 800,000 tonnes of pork, or one sixth of our total meat consumption.
I think people can chose to be vegan when the oil is cheap and industrial agriculture can deliver their protein,but if the system collapses,they will be getting their protein where ever they can
$this->bbcode_second_pass_quote('', 'w')e've been using the wrong comparison to judge the efficiency of meat production.
Instead of citing a simple conversion rate of feed into meat, we should be comparing the amount of land required to grow meat with the land needed to grow plant products of the same nutritional value to humans.
The results are radically different.
If pigs are fed on residues and waste, and cattle on straw, stovers and grass from fallows and rangelands – food for which humans don't compete – meat becomes a very efficient means of food production.
