Heidi Braacx, owner of Vegan Yarn, joins me to discuss the ethics and environmental impacts of wool, and why vegans don't use it. Heidi says, "Just because wool is biodegradable doesn’t mean it’s environmentally friendly”. We discuss plant-based alternatives to wool, and their respective impacts on the environment. Also, how can we, as consumers of clothing and/or fibre products, ensure we choose ethical products that have a minimal impact on our environment? Heidi has 3 steps for us.
