Wool is a natural fibre and because it is a hardwearing fibre, it is very durable.
As a result, a garment made of wool will last for years. A wool fibre can be bent more than 20,000 times without breaking. This makes clothing made of wool enormously strong. Some other advantages of biological wool are that the material is breathable and self-cleaning. After the sheep’s coat is shaved off painlessly, it simply grows back on again. What’s more, wool is biodegradable; the soil absorbs the nutrients.
But there are also disadvantages to that woollen sweater with a good quality. For example, wool has an impact on the earth because it causes more CO2 emissions. This is due to the methane released from the farts of sheep. The use of land and water is large because the sheep cost a lot of space and the wool has to be washed (often also with pesticides). Also in terms of animal welfare wool does not score high because sheep are not always well treated during shearing.
However, the living conditions of the sheep in organic farming are much better than those of the sheep in conventional farming. The soil is free of contaminants and no harmful chemicals are used to control parasites and moulds on the coat. Clothing made of organic wool can be recognized by the GOTS (Global Organic Textile Standard) logo that you find on the washing label on the inside of a garment or on the hangtag on the garment.
