A plausible definition of ‘sustainability’ in clothing

I’ve just come across the following quote in the introduction of Sass Brown’s book ‘Eco-Fashion’ (p.6):
“So what is sustainable design?
In clothing, it means sourcing and production that do not pollute through the process of manufacture and do not deplete non-renewable resources, whether those are planetary or human. It refers to clothing that can be absorbed back into the environment when it has reached the end of its life.”
