Extraction vs consumption bar graphs for water in agriculture, domestic use and industry from 1900-2025. Extraction bars are always smaller than consumption bars. Agriculture both extracts and consumes the most water followed by domestic use then industry. All three graphs show an increase of consumption and extraction but the separation of between the two bars grows over time. The most dramatic difference appears in domestic use followed by industry then agriculture. The difference between consumption and extraction is highlighted with a grey band. Water may be extracted, used, recycled (or returned to rivers or aquifers) and reused several times over. Consumption is final use of water, after which it can no longer be reused. That extractions have increased at a much faster rate is an indication of how much more intensively we can now exploit water. Only a fraction of water extracted is lost through evaporation.raw the least at lower than 15% for domestic purposes.
