Our class is going to hold a class meeting on the theme of protecting water resources. I am the host. Does anyone have a manuscript? First there are pictures of water shortages, and then it triggers students’ thinking.

Water - the source of life. Rain falls from the sky, nourishing all things; the stream sings joyfully all the way, sending a handful of nectar to dry lips in the distance, and adding a touch of green to the lifeless loess and sand. Water silently contributes to mankind and sows hope. However, today's humans believe that water is inexhaustible and waste water resources at will. Is this correct?

Background

According to surveys, the amount of water stored on the earth is very abundant, with a total of 1.45 billion cubic kilometers. Although the amount of water on the earth is huge, it can be directly What is produced and utilized by people is just a drop in the ocean. First of all, seawater is salty and bitter, making it unfit for drinking, irrigation, and industrial use. Secondly, the earth’s freshwater resources only account for 2.5% of the total water, and of these very few ice caps, more than 70% are frozen in the Antarctic and Arctic ice caps, plus mountain glaciers and permafrost deposits that are difficult to use. Snow, 87% of fresh water resources are difficult to use. The freshwater resources that humans can really utilize are part of rivers, lakes and groundwater, accounting for about 0.26% of the earth's total water. The global freshwater resources are unfairly short and extremely unevenly distributed. At present, more than 100 countries and regions in the world are lacking water. China is also a major water-scarce country, ranking 88th in the world. Of the more than 600 cities across the country, more than 300 are short of water, of which 108 are severely short of water, with a water shortage of about 100 million tons per day. Faced with these shocking figures, is it difficult for us to continue to be indifferent and waste the precious gifts given by nature at will?

Measures

Water is the basis of survival. In order to prevent the continued shortage of resources and to allow millions of our descendants to drink pure water every day, I propose the following suggestions:

1. Be aware of water conservation. If each person in the country saves one drop of water, 1.3 billion people can save 1,300 liters of water, and 474,500 liters of water can be saved in a year. Don’t look at this drop of water with disdain. Over time, it can turn a desolate wasteland into a bright one. garden.

2. Do not pollute water sources. With the rapid development of the economy, more and more factories are springing up like mushrooms after a rain. We should bravely point out that factory workers should abandon the bad habit of constantly discharging sewage into Hanoi and return the river water to pure and clear water. At the same time, I can also set an example and discipline myself not to throw away garbage, cans and other waste products in Hanoi.

3. Promote more. We must establish the awareness of saving water and everyone should follow the rules. Vigorously publicize the benefits of saving water resources, and use their free time to post slogans on the streets, so that people can consciously develop the good habit of cherishing the pure source of life and "turning off" every little thing.

Human beings, hurry up and use practical actions to cherish and cherish every drop of water, so that our motherland can restore the beautiful scene of gurgling water and lush trees, otherwise the last drop of water we see will be our own tears. !
