Check for the ecological footprint per nation or continent... water consumption is proportional to ecological footprint.
off top of my head,
North america by far outconsumes the world... in fact, it's been reported that if each person in the world consumes like the average American (don't even consider Canada), we would need 7-13 earths to have sustainable development that doesn't outpaces the consumption of natural resources to its production.
South America is relatively lower than NA. Middle East is a water crisis zone. South Asia is a water crisis zone. Rest of asia is quite high as well. Europe is after North America and Africa is next to nothing in comparison
we can deduce now that the more developed a nation, the more its water use per capita.
Photosynthesis- the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
