I only tuned in about half way through, but the thing that really struck me about the programme was the damage that natural fibres have on the planet.
I've been trying to avoid artificial fibres (although it seems impossible), because of the issue of microplastics, but was horrified at the effect growing cotton has had in Kazakhstan and the amount of water required to make a pair of jeans. (15,000 litres if I remember correctly?). In a world where so many people haven't got access to enough water, I can't get my head around that being acceptable.
And then the river in Indonesia... 
Coupled with the fact that even "good quality" clothes don't seem to last very long anymore, it feels like I'm being pushed into a cycle of increasing harm to the planet and some of the less fortunate people in it. And because the industry is so opaque, it so hard to know what are the choices I can make. Buying less is obviously an option, but it's not enough. The reluctance of any retailer (apart from Levi's) to engage was appalling and I was left feeling quite hopeless about the whole thing tbh
