Come on y'all... Take ur concentrates home and pan it there with the soap... And everybody will be happy ... Even the fish.
And where do you suppose that soap water ends up? With the fishes me thinks.
I think present day thinking sees the wilderness as pristine and everything bad comes from us. Nature commits genocide also. There is a reason I don't drink water from a mountain stream.
I agree with the philosophy of "Do no harm" but also know the trappings of over reaction. The people that indulge in over kill regarding our affect on nature are sometimes akin to those that want to end any human involvement at all. Ban all but the idea of take only pictures and leave only footprints. When I was involved in caving, that's what we did but caves are far less forgiving than life on top.
Kuger, when you state that Soaproot has the same effect as what we refer to as soap, what concentrations are you referring to? I don't want to seem anal but test data should proceed an assumption. There are many poison plants out there, There are two growing by my house. Deadly Nightshade and Jimpson Weed, along with a mushroom that pokes it's head out, Amanita muscaria. I know fairly close how much of each of them would harm me.
Many questions come to mind about poisons. It's concentration, to what and how does it degrade, it's life cycle. Saying "soap harms fish" is an over simplification of the question.
If we really want to live harmless we might need to hang ourselves with a hemp rope over four feet of active compost. I forgot who suggested that.
