Cotton vs Linen

Lately though, I have been doing a little bit of research regarding the sustainability of cotton. It is a natural fiber, and it does biodegrade after time (as sometimes, chemicals can be used in the process of creating the fiber). However, from planting to harvesting, enormous amounts of water is used. Even when growing cotton organically, without the use of fertilizers or pesticides, the amount of water is astronomical, and that sort of makes this fiber a less sustainable option than other natural fibers available.
