--If one can't find a public toilet and tries to constrict his/her sphincter muscle, could be bad  for his/her bladder or kidneys---Its a serious health issue

--The public hygene issue--could be minimised if people aim carefully at sewage outlets in designated sh1tting street blocks

--I mentioned before, a saint of a certain major religion urged his co-religionists to urinate and defecate far away from home. Legal prohibition could amount to religious persecution.

-- Public parks or green spots should have designated pissing holes near trees to collect organic fertilizers thus lessening demand for (petroleum sourced) chemical fertilizer

---GREEN PEACE should run street corner outlets to collect urine and feces and deliver such organic fertilizer to farmers and to help making the EARTH GREEN

.......

Comrades, no pun intended, I do occasionally piss into a bottle and water shrubs near my place with it
