I personally had no idea that the luffa sponges that I regularly use were from a plant! This is so crazy to me; I think I thought it was more of a man-made material than anything. You brought up some very good points during this post and I would have been on the same wavelength as you were with thinking that all-natural sponges came from the sea. That is after I found out it was an actual sponge ha-ha! I cant say that I have ever used them for cleaning anything other than my body though, so it was very interesting to learn that people do use them for other purposes. It also only makes sense unfortunately for use being the consumers that the rising demand for the luffa causes the price to coincidently go up as well.
Have you personally ever used them for some of the other tasks that you mentioned?
Great post this week and thank you for this awesome new knowledge and respect that I now have for something I only thought as a shower appliance!
Have a great week!
