evidence: Just on a side note, in the process of making this episode, I was told by one sales person that there is no such thing as "vegan leather" – much in that way that some people take issue with "vegan meat" being called meat. It’s either meat – or in this case, leather, or it isn’t. [...] And this sleuthing won’t be much easier when it comes to non-animal based leather shoes either. Even a product labeled "bio-based" might not be as sustainable as a company claims. [...] The final question we need answered to figure out the environmental impact of leather versus vegan leather is – How long will it be until the other shoe drops…leather or otherwise… right into the trashcan?
