水源是水的来源和存在形式地域总称。水源是生命之源，物质，信息，能量传递的重要中介，是地球表面生物体生存的不可替代的资源。水源主要存在于海洋，河湖，冰川雪山等区域。它们通过大气运动等形式得到更新。水源是人类从事生产生活活动离不开的宝贵资源。
水是生命之源，是人们赖以生存不可或缺的物质基础。假如人一天没有水喝，人何以有充沛的精力？被太阳炙烤了一天的盆栽植物得不到水的浇灌，植物何以能得到绿色的树叶呢？所以水与我们日常生活息息相关。既然水在我们的生活中如此重要，我们就有必要从源头上杜绝污染水源、浪费水的现象。
在日常生活中，一些建筑工地浪费水的现象较为突出，常常是几个水龙头不停地拧开，任由自来水哗哗地流个不停；一些不负责任的人整晚拧开水龙头，任水一泻而出，这些浪费水的现象屡见不鲜。而污染水源的现象也在我市比较突出。一些生活在河涌边、江河边的市民，缺乏应有的公民道德，为一时的方便，经常把一些生活垃圾抛弃在河涌里；一些人还把用完的农药瓶、杀草剂瓶等随便丢弃在河涌里，难道我们不感到保护水源、节约用水已到了刻不容缓的地步了吗？
Water source is the general term for the source of water and the region where it exists. Water source is the source of life, an important intermediary for the transmission of matter, information, and energy, and it is an irreplaceable resource for living organisms on the earth’s surface. Water sources mainly exist in areas such as oceans, rivers and lakes, glaciers and snow-capped mountains. They are updated through atmospheric movement and other forms. Water source is a precious resource that human beings cannot do without engaging in production and living activities.
Water is the source of life and the indispensable material basis for people to survive. If people don’t have water to drink for a day, why do people have plenty of energy? Potted plants that have been scorched by the sun for a day cannot be irrigated with water. How can plants get green leaves? So water is closely related to our daily lives. Since water is so important in our lives, it is necessary for us to prevent pollution and waste of water from the source.
In daily life, the phenomenon of water wastage on some construction sites is more prominent. Often, several taps are unscrewed constantly, allowing the tap water to flow continuously; some irresponsible people turn on the taps all night. Water rushes out, and these water waste phenomena are not uncommon. The pollution of water sources is also more prominent in our city. Some citizens living on the banks of rivers and rivers lack proper civic ethics. For a short-term convenience, they often throw away some domestic garbage in the rivers; some people also throw away used pesticide bottles and herbicide bottles. Don’t we feel that protecting water sources and conserving water has reached the point where it’s urgent to just throw it away in the river?
