Did you know that to grow $1 worth of rice in Australia needs over 1700 litres of water?

That is a lot of water for a small amount of food. I’m not sure how much water it takes in other countries but it is less than Australia because they grow rice in wet areas - we grow it closer to the desert than the coast. 

Maybe some scientists could find a way to grow rice with less water? Or maybe we need to find better places to grow it?

I wonder if brown rice is better because it uses less water in processing?
