So-called virtual water exports 'the molecules of H20 embedded in exported goods, alongside those rendered unusable by the production of those goods' amount to a net 95.4 billion cubic metres a year, according to data collected by the Water Footprint Network

Drawing a connection between the use of water and meat consumption by quoting Water Footprint Network

"The size and composition of a nation's per capita ecological footprint reflects the goods and services used by an average person in that country, and the efficiency with which resources, including fossil fuels, are used in providing these goods and services," said the report, which was created in collaboration with the Zoological Society of London, the Global Footprint Network and the Water Footprint Network

In an effort to get consumers, companies, and entire countries to recognize the true costs of their water use, a few environmental groups are promoting the concept of out "water footprint." The idea "very much brings the water problem to the people," explains its creator, Arjen Hoekstra, scientific director of the Netherlands-based Water Footprint Network
. Just as calculating carbon footprints has encouraged--and shocked--many Americans into seriously considering their personal environmental impacts, Hoekstra hopes that water foot-printing will reveal the gushing faucet behind every purchase we make.
