Wool is a versatile and sustainable fabric that can be obtained from several different animals, including sheep, alpacas, goats, llamas, yaks, and even rabbits. However, the ethical considerations for each type of wool can vary greatly.

Merino wool is one of the most popular types of wool, known for its softness and lightness. However, the selective breeding of Merino sheep for their wrinkly skin can lead to heat exhaustion and an increased risk of fly-strike disease, which is often addressed through the inhumane practice of mulesing in Australia. To ensure ethical production, consumers should look for labels like the Soil Association Organic, ZQ Merino Standard, and Responsible Wool Standard (RWS).

Angora wool, produced using the silky fiber from Angora rabbits, is often associated with animal cruelty due to large-scale production methods that involve plucking the fur, causing pain and distress to the rabbits. While ethical Angora wool is possible on a small, non-commercial scale, it is generally recommended to avoid this type of wool unless it is sourced from ethical and sustainable practices.

Cashmere wool, known for its high-end comfort and warmth, is often linked to environmental degradation and underpaid workers. However, consumers can look for recycled cashmere fibers or certifications and standards like the Recycled Claim Standard (RCS), Good Cashmere Standard ® (GCS), and Global Organic Textile Standard (GOTS) to ensure ethical and sustainable production.

Alpaca wool, on the other hand, is known for its eco-friendliness and gentle grazing practices. While the farming practices and animal welfare standards for alpacas can vary, ethical alpaca wool is possible when raised in small, free-roaming herds and gently shorn using traditional hand methods. Consumers should do their due diligence to ensure ethical and sustainable production.
