Water is very important to the human beings.But now many rivers and lakes are polluted.
And what shall we do ? We can do like this:
First we must prevent the factory from pouring waste water into the river
Second we should stop people from throwing litter into the river.Many kinds of litter may pollute the environment.
Finally we can tell the visitors how important the water is.
After doing these things,I think water will become cleaner sooner or later.
Water is very important for living things. Without water there can be no life on earth.
As we can see, the world population is growing rapidly day by day. So enough fresh water is needed to feed such a big population. What's more, with the development of industry, factories and vehicles produce poisonous gases or wastes, which consequently results in the pollution of water. Though fresh, a good amount of it can no longer be used. Only quite limited fresh water resource is available to human beings. So it's high time for us human beings to take quick action to protect water resource. Stop pollution and save water, otherwise, we cannot survive on the earth.
Water is indispensable to our life and the development of national economy. It is often described as the source of all living things and the lifeblood of agriculture and industry. Without it, nothing could grow and out world would become a terrible desert.
The world we live in is now faced with a severe shortage of fresh water. According to some official figures, more than 1,700 million people in the world don't have enough clear water to drink and over 25 thousand people die of water related diseases daily.
So, all of us should actively b save water. It's our obligation for the benefit of the future generations.
