Steping light years ahead of the crowd.
A cheap, and reliable method for a toilet already exists.
Buying a toilet, putting it in. Making it clean, is all about ones own comfort. It has little to do with enivornmental protection.
come on step ahead, jump light years beyond the crowd. If you really are in to environmental protection, beyond your own comfort. Take your poo and your wee and put it in a pot. Carry that pot home and use your own toilet.
Think it is disgusting? Not me, I think that if you are brave enough to be a rock climber you should be brave enough to deal with your own waste.
Step up and stop patching the problem, deal with it. Zero impact. This option costs so little you can by more chickens and beer at old Ma Joe's
Vietnamese coffee? High in fat, low in fat? Vietnamese coffee.
