Presentation for Primary School Students: Protecting Water Resources.
Dear Teachers and Students:
Hello everyone! Water is the source of all life, 60% of the weight of the human body is water, 90% of the blood is water, and we each need two kilograms of water per day to sustain life. Water is again the primary resource in production
It takes 1,400 cubic meters of water to produce one ton of rice, 200 cubic meters of water to smelt one ton of steel, and 500 cubic meters of water to make one ton of paper. It can be said that without water, humans would not be able to survive.
Students, do you know when you turn on the faucet and take a cool shower comfortably in the scorching summer? The water you use for bathing is the daily water consumption of dozens of people in water-scarce areas; When you flush the toilet, you use as much water per capita per day as a developing country; When you are careless and do not tighten the tap, it loses water in one night, equivalent to ...... daily drinking water for residents of a village in a water-scarce region of Africa or AsiaThese cases are by no means sensational, but the result of years of investigation by the relevant United Nations bodies.
As we all know, China is a water-poor country, with only 2,240 cubic meters of fresh water per capita, less than a quarter of the world's per capita level, ranking 109th in the world, and being listed as one of the 13 countries with serious water shortage in the world. Due to the shortage of water, China's rural grain production has decreased, desertification in northwest China is serious, and sandstorms occur frequently. Water conservation is a top priority for every Chinese.
However, looking around, it is not uncommon to destroy and pollute water resources, just take the Lishui River outside!
According to the old people, a long time ago, our Lishui River was so clear, so beautiful, like a piece of green jade, in the river, fish and shrimp swam happily, on the shore, people lived happily. People like to drink the clean water and taste the fatty fish and shrimp, and in the summer, the river is full of people playing to their heart's content.
Decades have passed, and our river has changed, the water is no longer clear, the fish and shrimp are no longer fat, and people no longer drink the river water directly. What is the reason for such a change in the river? Mankind!
We humans are to blame! For decades, people have dumped garbage into the river, factories have been dumping wastewater into the river, and hospitals have been dumping sewage into the river ......Day after day, year after year, our mother river, the Lishui River, has become muddy and scarred! In some places, the riverbed has even become a stinky ditch for garbage.
In the summer, people no longer dare to play in the river......All of this is evidence of human destruction of water resources!
Students, "** priceless water is priceless". For the sake of our own health, for the happiness and tranquility of future generations, and for the future survival and development of human beings, let us take active action, start from the small things around us, start from little by little, save water, protect the water resources we rely on for survival, and be a "little citizen of environmental protection" who cherishes water as gold! Let advertisements like "the last drop of water on earth will be human tears" will always be only advertisements!
Thank you!

Who doesn't want the sky above their heads to be as blue as a mirror, who doesn't want the earth under their feet to be green and grassy, who doesn't want the lake around them to be clear and clear, and who doesn't want the sun in front of them to be as bright as gold. >>>More
