Will Everyone Be Vegetarian in Future? - as part of the news series by GeoBeats.
Humans may have to go to a strictly vegetarian diet by the year 2050 according to new information that's been discussed at the World Water Conference in Stockholm, Sweden.
UN bodies, researchers, and politicians from over 100 countries are exploring how to deal with our global water supply crisis.
The research suggests that a significant reduction in worldwide meat consumption may be needed to address the water shortage.
The water scientists studying our global food supply say, “There will not be enough water available on current croplands to produce food for the expected 9 billion population in 2050. Humans derive about 20% of their protein from animal-based products now, but this may need to drop to just 5% to feed the extra 2 billion people expected to be alive” in the next 40 years.
Currently, about 70 percent of all useable water is used to either cultivate crops or to provide for animals. Producing protein-rich foods involves using 5 to 10 more times water than a vegetarian diet. This means greater burden on resources needed to feed the human population by 2050.
