Why are sheep important and how do they help man?
There are about 7 times more sheep than people in New Zealand that is around 31 million sheep. Wool is very strong and it is measured in microns. The higher the number of microns, the stronger the wool. A single wool’s fiber is stronger than steel of the same diameter. Every home has wool in it and because it doesn't burn easily, it is very safe. It takes less than 2 minutes for a professional shearer to shear a sheep. The world record is 30 seconds (naturally set by a New Zealander). Sheep are shorn so the fleece comes off in one piece. N.Z is one of the top 3 wool-producing countries in the world exporting 130,000 tonnes a year. Wool is long lasting which means that wool can bend back to 20,000 times without breaking. Together, cotton fibers can only bend up to 3200 times. Wool can be extended up to 70% of its natural length and when the tension is released, it returns to its natural length. Llama wool as well could make clothes too.
