Natural fibres like cotton, linen, hemp and bamboo have various pros and cons – they break down quicker when disposed of and don't create demand for synthetic oil-derived plastics. Cotton biodegrades easily and can be spun into a durable fabric without requiring a complex chemical process, but is a very thirsty crop. Linen can be more efficient in land and water use, but takes a lot of time to process and is quite a delicate fabric. Hemp can be most efficient when it comes to land and water use, but can take more time to wear in. Bamboo grows quickly and without the need for pesticides, creating a hard wearing fabric but requiring a very intense chemical process to produce.
