yea abt 10,000 litres to produce 1kg of cotton. The good thing abt cottonique though it doesn't have industrial dyes which is often one of the biggest causes of harm because of water going back to ground, evaporating or to the rivers. Interesting that merino is more durable than cashmere! I've been pretty interested in cotton mixed with vegan produce like pineapple husk and bamboo (30-70 ratio)
