As we all know,the shortage of water source has become one of the most serious problems us faced today.Therefore,we should educate people to save water in their daily lives.
The picture above illustrates a model example of water economization.It shows that we can reuse water in many occasions.In the first place we can use clear water to wash rice and then use rice-washed water to wash vegetables so that we can not only reuse water but also make the vegetables more clear and safe.This is because,there are some components in the rice-washed water can help filter the chemical poisons left on the vegetables.After that,though the water would not be that clear,it can be used to mop the floor.
Now,most of us use clean water to flush toilet which is a huge waste of water.As the picture shows that we can use the dirty water flush instead.
As a conclusion,in my opinion the best way to save water is to make everyone aware that how to save water in their daily lives."Many a little makes a mickle",if everyone realises the importance of water economization and acts a good example for their children it will bring a great benefit the families as well as to the whole country.Besides,this is also critical for the further generations.
