In March, the ABC aired a story showing footage of pigs in Australian abattoirs being stunned with carbon dioxide before having their throats cut. Packed into small, gas-filled chambers, these animals could be viewed writhing, gasping and screaming in distress, some foaming at the mouth.
The pigs’ suffering was not an aberration; it is what countless pigs around the world commonly endure before being turned into ham and bacon. Such media exposés reveal how far we have – and have not – come since Australian philosopher Peter Singer published the seminal book Animal Liberation nearly 50 years ago.
