I'm trying to understand your examples. Those are absolutely massive quantities of water you're mentioning for cooking, washing and farming. I assume that you cook and wash yourself like everybody else, and have a basic understanding on how much for example a head of cabbage should be watered each day. So what do you mean with these numbers?

cooking includes the running tap under which you peel the potatoes, the water you boil the eggs in, etc. washing includes the 150 liters a washing machine uses or the 100 liters in a bath or shower.[3] Spraying things down with a hose really uses a lot too. farming is the one with most variance - but some crops have a super high number of liters of water used per kg of crop harvested. 1kg of rice = 5000 liters of water! [4] For things like beef, you really need to include all the water to grow the grass too...

  I cook everyday and there is absolutely no way that a normal family yet a single person would be using 20l of water per day to cook, unless they were deliberately aiming to use as much water as possible. Including washing dishes etc. The example stated for farming is 2000 liters per person per day for food. I'd like you to pause for a moment and think about that statement. A person can't eat a whole head of cabbage in a day, and you're saying that this head of cabbage would need more than two tons of water per day before it's harvested. Likewise with the washing machine, you're talking about washing a full load per person every day. Who do you know that soils so much his clothes that he needs to wash a full load only for him every day? Water to grow the grass for beef cattle is rain, as I assume at least a small minority of people reading here will know. Your original comment is greatly upvoted and the people here actually believe that two tons of water per day per person is needed to grow their food. Per day. Per Person. I can't fathom what is going on in this forum.

I just looked at my water bill, I am at about 150L/person/day, which is about average for my country. It includes drinking, cooking and washing. So less than then the 200+20+2 estimate but not by that much, if you enjoy baths and lengthy showers, 222L is possible. And from what I've seen 2000L/person/day for agriculture is not too outlandish. The production of your garden is likely to be tiny compared to what you eat. A head of cabbage is maybe 1/10th of you daily calorie needs, and compared to animal products, vegetables have low water requirements. So maybe it is not exactly right, but the orders of magnitude look correct. At least for the first world.

  In the Netherlands farmers and industry pay a lower rate than households. It is only recently with climate change that an ATTEMPT is made to get water use down. For millennia the country drowned in water and the issue was pumping it to the sea not preserving it.
