My usage of water shouldn't exceed 400 kgs per month. That includes drinking, bathing, flushing, cleaning, cooking and washing hands (I even have a weird habit of doing that excessively). You can't get that much wasted water from that usage.
Actually, I noticed the word average just now. I am packing my bags.
You also need to factor in the wastewater to produce all of the other products you consume. That produce you bought at the store and rinsed yourself was also likely washed several times along the supply chain before it got to you. That one bottle of beer you drank? The bottle has been washed several times, inside and out, along with the vat the beer was brewed in, every single pipe and tool that was used to process or shunt it, etc.
What about frequently checking replies page out of FOMA?
What about the content I watch or read? The anime I watched last took lot to produce and there is no doubt, people wasted shit ton of paper along with other things are?
That is quite a lot of waste in terms of energy.
