WHY do i consume the amount of water i do?

15 minutes is a long time to spend in the shower every single day. Cutting that down to 10 would help a lot (5 would be ideal). Always turn off the water when you brush your teeth. The water only needs to be on for a second to wet your toothbrush. Why leave it on? Don't worry about the water you drink (though you should get a brita instead of bottled, because the plastic bottles are very wasteful) That seems like an awful lot of laundry. I guess with that just make sure to wait until you have a full load. Maybe someday get a washer that uses less water (front loading ones tend to use less)
