Asking for a report on the Cherishing the Water of Life is not an essay that cannot exceed 300 wor

Taiyuan News Network News Hands-on self-made rain gauge to measure summer rainfall; field measurement of the pH of domestic water; Learn meteorological knowledge and try to "see the clouds and know the weather" ......Yesterday, the "Cherish the Water of Life" provincial youth scientific investigation experience activity was launched in Xiangtang Primary School in Xinghualing District. From now until the end of August, millions of primary and secondary school students in the province will learn to understand the knowledge of water resource utilization and water pollution hazards through scientific experience such as water quality testing, soil and water conservation conservation, and wetland water conservation, so as to improve their awareness of water conservation.

Cherish the Water of Life" Youth Science Investigation Experience Activity, initiated by the Youth League ** and the China Association for Science and Technology, aims to improve the awareness of water hazards, water conservation and water resources protection among young people.

According to the person in charge of the Provincial Youth Science and Technology Activity Center, the majority of primary and secondary school students in our province will carry out water-related scientific investigation activities at home and school (class or group), and the students will experience the preciousness of water resources through small experiments with novel designs and easy to learn and understand. Among them, the experiment of "protecting vegetation and soil and water" can simulate the different scenarios of rain on grass slopes and soil slopes, and teach everyone to understand the truth that "only by retaining the root system of plants can soil erosion be avoided"; The experiment of using dry and wet sponges to simulate wetland water conservation vividly demonstrates the water storage capacity of wetlands, and if wetlands are destroyed on a large scale, it will lead to the evil consequences of "drought if it does not rain, and waterlogging when it rains".

At the same time, it will also organize and carry out scientific experience and scientific activities related to domestic water, industrial and agricultural production water, collect and sort out relevant materials and data, conduct simple data statistics and analysis, write investigation reports, and put forward reasonable water-saving suggestions.

It is reported that since 2007, every summer vacation, our province will carry out scientific investigation and experience activities on different themes such as energy saving, paper saving, and low carbon, and about one million teenagers have benefited from it every year.

Cherish the water of life, saving starts with me.

Cherish the water of life.

Water is the source of life! 70% of the body's body weight is made up of water.

People can't do without amniotic fluid in the mother's womb, and they can't do without water after birth, and people can go without eating for three days but not drinking water for three days. The human body is made up of cells, and cells need water exchange to complete metabolism all the time, so we must cherish the water of life.

At present, we rarely see clean water around us, and most of the rivers are polluted to varying degrees, which are not easy to avoid due to the development of industrialization and urbanization. With people's safe and healthy drinking water under threat like never before, what can we do in the face of increasing water pollution?

We must cherish the water of life, love the earth on which we live, and put an end to any behavior that destroys the environment, starting from each of us, starting from now. We should take care of the environment and oppose pollution as our own business.

According to the data, at least 100 million tons of sewage are discharged into water bodies every day in cities and towns across the country without treatment. One-fifth of the country's water bodies are not suitable for fish survival, and 90% of urban waters are seriously polluted. The main pollutants of water pollution are the following:

1.Untreated industrial wastewater.

2.Untreated domestic sewage.

3.Extensive use of chemical fertilizers, pesticides, herbicides, road snow removers, etc.

4.Industrial waste and household waste piled up near the river.

5.Soil erosion.

6.Mine pollution.

7.Industrial and chemical contamination from other emergencies.

In fact, we live in an environment that is heavily polluted, and most of all the pollution ends up flowing into the water, adsorbed in the water, and neutralized in the water! This is a wake-up call for our healthy water. The water we drink today determines the health of tomorrow.

Looking back at the past 2010, there were more than 10 water pollution incidents in large areas

1.Shaanxi Luochuan water pollution incident.

2.Shenyang Tuanjie Reservoir water pollution incident.

3.Water pollution incident in Bayan County, Heilongjiang Province.

4.Water pollution incident in Zijin Mining in Fujian.

5.Dalian oil pipeline ** pollution incident.

6.Jilin chemical barrel drifted into the Songhua River pollution incident.

7.3,000 tons of toxic water dumping pollution incident in Dongying.

8.Nanning underground sewage pipeline pollution incident.

9.Anhui Qianshan tap water pollution incident.

10.Zhongjin Lingnan "thallium pollution gate".

11.Jiangsu Meilan Chemical chloroform pollution incident.

What a shocking water pollution! If we continue to do this, it will be difficult to find safe drinking water in the world!

As an environmental protection worker who deals with water every day, I hope that our motherland can continue to strengthen environmental protection and crack down on all behaviors that endanger the safety of human drinking water, so that our nation and people can drink safe and healthy water.

Human beings do not cherish water resources and do not protect the ecological balance, and after all, they still taste the bitter fruits of their own planting.

Today, many people drink contaminated water and chew contaminated food every day. While people enjoy modern industrial civilization, they also suffer from the threat of water pollution, which causes social losses and economic losses that can be listed in non-numerical numbers. This is nature's revenge on mankind, and it is a great mockery of human beings' own fault!

Water is the source of life and the foundation on which all things depend. It is the duty of each and every one of us to save and protect water resources. For the sake of the lovely and fragile earth, let's cherish and protect water resources together.

A hymn to life.

Life is a small stream, from snow-capped mountains or underground springs, meandering through lofty mountains, grasslands and valleys, screaming and jumping towards the blue sea;

Life is an evergreen vine, absorbing the nourishment of the earth, bathed in the moisture of sunshine and rain, silently and quietly showing its green branches and green leaves on the hillside meadows and cliffs;

Life is a flowing beam of light, burning itself to the fullest and fiery, decorating the firmament, and finally merging into other objects in the form of energy;

Life is an endless cave, in which strange rocks, winding paths lead to seclusion, heavy roads and waters, and there are caves, which is always a fascinating, but confusing mystery scene.

Life is a sheep's intestine path, bypassing thorns in the overgrown weeds, bypassing the pits on the gravel slopes, winding through the green hills and beside the green waters.

Life is a mystery, a mystery that people in the red dust can never solve.

There is nothing nobler and greatest in life than to explore it!

There is nothing more meaningful in life than the study of life!

There is nothing more exciting in life than the reverence for life!

There is nothing more calming in life than to follow the trajectory of life!

Students:

You've all seen a public service announcement where there's a faucet on the TV screen, dripping water out with difficulty, and the dripping speed is getting slower and slower, and finally the water runs out. Then a pair of eyes appeared on the screen, and a tear flowed from the eye.

This was followed by the phrase: "If humans do not value water, then the last drop of water we can see will be our own tears." ”

Water is the source of life, and if there were no water on earth, then Mother Earth would not have given birth to our human offspring. Because the earliest primitive life was first conceived in the ocean, and gradually spread to the land. Therefore, water is the cradle of life.

Water is also indispensable for the survival and development of human beings. Because we need to drink water every day, the growth of food is inseparable from water, and industrial production is inseparable from water. Water is still the "air conditioner" of nature, and in the hot summer, when people feel the scorching heat, how happy it should be to have a rain!

Walking on the beach, the sea breeze swept away the hot and irritable mood; When the cold winter season arrives, the sea water sends a steady stream of stored heat to the land ...... around itThese are the effects of water.

Although our country is very rich in water resources, there are very few freshwater resources that can be used, and with the development of industry, water pollution has become a serious problem, and a lot of industrial wastewater is polluted to the point of smell, what a terrible thing! In addition, the phenomenon of wasting water is also very serious, according to statistics.

A medium-sized city wastes as much water as one Dongting Lake every year! March 22 is World Water Day. Every year on this day, countries around the world promote:

We should cherish water resources and protect the water of life. In fact, not only on this day, but also every day in our lives, we should cherish every drop of water and cherish the water of life with practical actions!

The total amount of water that the Earth has is about 13.6 billion tons, of which about 100 billion tons of salty seawater is there. Due to salinity issues, seawater cannot be used as a water source by life on land. The distribution of water on Earth is roughly as follows:

Oceans, polar icebergs, groundwater, lakes and rivers, and water vapor in clouds. (See Figure 1).

Fresh water on land comes from the sky. The sea water evaporates in the sun, the salt remains in the sea, and the fresh water evaporates into the sky, forming clouds. The clouds are blown over the land by the wind, condense and fall to the earth.

In this way, rivers, lakes and wetlands on land are formed, which are the source of fresh water for life on land. (See Figure 2).

The total amount of freshwater on the planet is about 100 billion tons, which is the total amount of water on the planet. However, such a finite amount of freshwater is found in several forms of solid, liquid and gaseous forms in glaciers, groundwater, surface water and water vapour on land, with a proportional distribution of:

Polar glaciers account for 75% of the Earth's freshwater, which is almost unusable;

Groundwater accounts for 8,600 trillion tons of the earth's total freshwater, but half of the groundwater resources are at depths below 800 meters, which is difficult to exploit, and over-exploitation of groundwater will bring many problems;

Rivers and lakes account for 230 trillion tonnes of the Earth's total freshwater, and are the main source of freshwater resources for plants, animals and humans on land.

The amount of water vapour in the atmosphere is 13 trillion tons of the Earth's total freshwater, and it replenishes the land with fresh water in the form of rainfall.

Fresh water on land is scarce because it evaporates from the sun or returns to the sea through surging rivers, and less than three thousandths of the earth's total water is available for life on land.

It's all two, and I don't know the homework of that dead baby. There is a lot less homework in the eighth middle school than we do.

It's just that I really don't know that the second middle school has arranged so much homework and is tired to death.

The theme can be described as water saving, starting with me.

Dead and rotten No. 2 Middle School, arrange a lot of ghost homework to play the ball!!

Cherish the water of life.

We know from the recent drought in the southwestern provinces that people cannot live without water, without which animals, crops and even humans cannot survive. Without water, there would be no life, and without water, the earth would be dead and silent.

As we all know, more than 60% of the earth's area is covered by water, but few people know that the total amount of freshwater available for human use in such a large amount of water accounts for only 3/100,000 of the total water on the earth, accounting for the total freshwater storage. At present, more than half of the world's land area and more than 100 countries and regions are short of water, and more than 2 billion people have difficulty drinking water. Humanity is consuming water resources at a rate that doubles its freshwater demand every 15 years.

To date, human freshwater consumption accounts for 54% of the world's available freshwater. China's total water resources are trillions of cubic meters, per capita water is less than 2400 cubic meters, only 1 4 of the world's per capita water volume, ranking 110th in the world, China's total water resources, available water reserves are only trillion cubic meters, and the current water consumption has reached 560 billion cubic meters, the city is short of 6 billion cubic meters of water every year, more than 400 of the country's 668 cities have insufficient water supply, of which 108 are seriously short of water. Due to water shortage, more than 230 billion yuan of industrial losses are caused every year.

If we don't conserve water, the consequences will be dire. Therefore, the water available to us is very limited compared to the continuous development of industrial and agricultural production and the growing population, so it is imperative to conserve water.

Every day of our lives, we should cherish every drop of water and cherish the water of life with practical actions.
