What is vividly revealed in the picture is that water is being reused in daily life at home. After washing rice, the water can be used to wash vegetables and then clean the mop and the toilet. What a harmonious scene it is!
　　It is not difficult to find that what the picture intends to express is the importance of saving and protecting resources. On the one hand, as we all know, water resource is limited and water shortage is still a serious problem threatening the existence and survival of the whole human being. On the other hand, the phenomenon of wasting water can still be easily found anywhere in our daily life. For example, water taps are frequently left on by careless users. Someone even assumes that they have the right to waste water because they pay for it o that it has nothing to do with others. In fact, so precious water is that we cannot afford to waste it. Water resource is not only indispensable in our daily life but also in the industry and agriculture. It is hard to imagine what the world would be like when there I is no more water.
　　It is fortunate that now the public is starting to pay attention. But, this is not adequate. As is shown in the above picture, what we need is more actions to save and protect resources! First of all, social environment is shaped by the general public, and the cultivation of conservation-minded society depends on the active involvement of every member of our society, be he old or young. Accordingly, an education campaign should be launched to call on people from all walks of life to save and protect resources. In addition, saving and protecting resources is bound up with our daily life. We, college students, should spare no efforts to save valuable energy and natural resources such as power, water, coal, gas and so on. Only by the joint efforts of the whole society can we create a real conservation-minded society.
