PETA and Austrailian Farmers Fight over Sheep

Hello world,
Last week, the People for the Ethical Treatment of Animals said that they would boycott the wool industry if Austrailia refused to stop mulesing their sheep. Mulesing is a process where extra skin is removed from the area of the anus of the Merino sheep in order to prevent flystrike, which slowly and agonizingly kills the sheep. Austrailia's wool industry has promised to end the practice as a condition of the Trans-Pacific Partnership, which would give Austrailian wool farmers the right to sell wool in the US, Brinei, Chile, New Zealand and Singapore. The industry argues that a better way of preventing the disease has not been found, but PETA argues that the procedure is cruel and unnecessary. I think that if this is the best way to keep the sheep from dying, then it should be done. Why is PETA sticking their nose in it anyway?
