The importance of water
Of all the things we eat and drink, water is the most important. We can live without food for many days, but two or three days without water, usually makes people die.
However, not all of people understand this. They keep throwing rubbish into the rivers or lakes . Some factories even pour waste water into the river. As a result, many rivers and lakes have become so dirty that the water is no longer safe for people to drink .
Let’s do our best to keep the water clean to save ourselves .
