In the picture,four men are gathering under a shower. They are staring at the shower expectantly,but only a drop of water comes out from it. Under the picture,the caption reads:"If you waste water today,you won't have any water for bath in the future." The intended message in this picture is that we should cherish water,the valuable resource,which will dry out one day if we do not learn to save it.
As a matter of fact,water is as valuable as fossil fuels and other natural resources. Some people might think that water is infinite and could be recycled again and again. Therefor,they never bother to think about saving it. Water is,indeed,renewable,but fresh water and clean water are rather limited. For instance,in some African countries,people are inaccessible to fresh water or clean water. They live in an inconvenient life and are prone to diseases transmitted by dirty water. If we don't cherish water,the situation in the picture may occur in the future.
To sum up,saving water is of great importance. It is necessary for everyone to economize on water resources.
