Beef tallow in beauty

I just watched the latest video from Hannah Louise Poston where she talks about a beef tallow cream among many other products. Honestly I was taken aback by that review. She raved about the product. During a time in which we should all be trying to reduce our carbon footprint I find it extremely weird to promote the use of a product which is made of beef fat (that's what tallow is). The beauty industry is already quite polluting and not great for the environment - do we really need to add animal products to our beauty routine? I don't think so. Also, my sense is that this is yet another fad in the beauty community. But I'd be curious to hear other people's opinion on this.
