I used to produce a product made from the oil of a nut from a tree found in the Amazon rainforest. Harvesting the fruit did not harm the environment whatsoever, in fact, gowing trees that provided the product supported continuance of the old growth forest. Unfortunately, through deforestation over decades for pasture land, this tree has been essentially been eliminated and the scarcity of the oil made the product go the way of the dinosaur.
I have since found another source of the saponin, that which I mentioned earlier in this thread. It is harvested ecologically and in a 'fair-trade' manner by indigenous tribes of the Himilayas, thereby providing them a decent earning, and at the same time, helping maintain the balance of nature.
