The National Farmers Federation says that “mulesing remains the most effective practical way to eliminate the risk of ‘flystrike’ in sheep” and that “without mulesing up to 3,000,000 sheep a year could die a slow and agonising death from flystrike”.

A fiber farmer is heavily invested in the health and well being of their animals for the simple reason that an animal that isn’t happy and healthy can’t produce a sell-able product. An animal going through a period of stress of any kind produces a fiber that breaks.

Wool fiber has properties that make it unequaled by many other natural fibers/ Lanolin is also a critical oil that cannot be replaced with other oils. Lanolin and its many derivatives are used extensively in both the personal care (e.g., high value cosmetics, facial cosmetics, lip products) and health care sectors. Lanolin is also found in “lubricants, rust-preventative coatings, shoe polish, and other commercial products”

In some cases, the products derived from sheep make up a very large portion of a country's GDP. Banning sheep farming could cripple a country like New Zealand economically.

That said, obviously there are some horrible scenes in the video. Obviously there needs to be more oversight to control abuse to the animals. However, I would like to point out that the video did cherry pick a couple of companies that had egregious policies. Also, if the mulesing that was shown was part of the PETA video, it was staged with a fake lamb. PETA even admitted they staged that video for 'educational' purposes. I don't know if it was the same clip, but just putting that out there.
