Instead of showing the next person how much more you care about the environment than they do by leaving piss and/or shit in the toilet ,maybe just offset your water waste by not wasting food/ drinking tea a handfull of times a year instead of coffee ( it takes 1000 gallons of water to produce one gallon of coffee vs 100 for tea ). literally drinking tea for a week instead of coffee or not wasting a couple meals worth of food will save an exponentially larger amount of water. basically.... if you are smart about what food you eat and DONT WASTE FOOD you you could take a 4 hr shower everyday and do less damage to our water supply.........its whatever 50s style wedding dresses tea length
