I dunno... there is no substitute for the good soft 3 layer TP ,that I know. And I have seen a few during my life.
The worst I've seen was the British Army TP in the 70s and 80s, a stuff similar to baking paper. Painful and inefficient at the same time. I guess it could also be used to wrap your gun into it and bury it for 20 years, and it would preserve it perfectly.
But of course we can take steps to save TP. For one, strictly using recycled paper, and secondly stop being a crumbler and become a folder. Most people in Germany are folders, while most Americans are crumblers, did you know that? They did a scientific survey about that, no kidding.
If you crumble, you need more paper in average as if you fold. And on millions of people that already makes a big difference.
