The more I read, the more it boggles my mind. If you really want to knit or crochet “green“, what’s the best choice? The best answer I’ve come up with so far is, “It’s very complicated!” The more I read, the more complicated it becomes.
Wool to some is suspect because of some of the farming practices used and the amount of methane the sheep produce impacting global warming! I’m not kidding! see this Green Latern article in Slate.
Cashmere farming has caused land deforestation resulting in drought.
Cotton needs too much water and a lot of pesticides.
Other fibres required extensive manufacturing processes and chemicals (information of these procedures are not easily available because companies guard their manufacturing secrets to protect their product.)
Yarns that are touted as eco-friendly, like bamboo, are really manufactured yarns. Silly me thought that bamboo was a bast fibre like flax. Not so! The fibres of the actual bamboo plant are too short to be spun. In her book “No Sheep for You”, Amy Singer lists bamboo in the “Manufactured Fibers from Natural Materials” section along with Rayon, Lyocell (which includes Tencel (r)), Seacell (r), corn, soy and Modal (which has been around since the 1930’s).
What to do, what to do?
