About water ploblem Now, I'm learning about water problems at school. So I write about how I think to solve that. I think it is important not to buy too much food. There are so many kinds of foods in developed countries, and you will want to buy them. But you can't eat up all of them and the foods you can't eat up will be throw away. This is waste of "virtual water". So you have to buy food as much as you can eat. And don't forget we are shering the water as "virtual water ". The more the number of developed countries increase, the more food will be consumed. The water we can use is limited, so we have to use it (with?) saving.
