True or False
True or False: We need more water than we currently have to grow more food.
The answer is FALSE
According to the WWF, it's not the total amount of water that is the problem - it's how we are using it.
Currently the world is drawing on 54 percent of the world's accessible freshwater, says WWF, with 70 percent of that used by the global agriculture sector. But 60 percent of the water the sector uses, or 1,500 trillion liters, is "wasted through inefficient irrigation methods", it says.
Take rice, for example, which half of the world depends on for food - every kilo of rice produced requires 3,000-5,000 liters of water. Alternative methods of farming can remedy this, says WWF, citing 'system of rice intensification', or SRI, which it says in trials have show increased crop yields while using 30 percent less water.

Floods in Mexico / Droughts in Tennessee and Georgia
how do you show pictures of an urban drought? i just tried and failed to find any of note or that spoke the volumes of the photos above. and then i found this one ---
which could just be a creepy add for poland spring, until think for a second and realize this dude's in a fallout shelter. doesn't really scream drought, but gets the idea of impending disaster across. i like this image of a man surrounded by bottled water.
