What cause the supply of wool to decrease?

The supply of wool can decrease due to several factors, including adverse weather conditions such as droughts or floods that affect sheep farming. Additionally, rising costs of feed and maintenance can lead farmers to reduce their flock sizes. Diseases affecting sheep populations and shifting consumer preferences towards synthetic fibers can also contribute to a decline in wool production. Lastly, trade restrictions or tariffs may limit the export market for wool, impacting overall supply.
