water
Recently, I have been writing about only formal things, but I have nothing else to write.
All animals and plants cannot grow up without water as well as oxygen. When I think about drinking water which is essential for us living, around a billion people are not able to use clean safe water now. From now on, world population will make the rapid increase. How can we obtain water and share it? Human beings cannot live without water any longer than one week. In Japan, almost all people don’t have difficulty in getting water. We can always use it when cooking, taking a bath, playing in the water, and so on. However, after thinking about it carefully, we depend on overseas water. It is `virtual water` that I think of. The food self-sufficiency ratio in Japan is around 40 percent. This means that Japan is a close connection with foreign countries through importing `virtual water`. We can think about importing foods as importing water. From this viewpoint, Japanese people must not be optimistic about water shortage. There are a lot of people who suffer from a lack of water right now at this moment. We should reconsider the way of using water.
