An old man with a face full of vicissitudes of life faces the smelly Sushui He was filled with grief and anger. As a tributary of the Fen River, the Sushui River was originally very clear. Without it, the prosperity of Yuncheng, Shanxi would not exist today. But now, Sushui River is embarrassing - the silent old man is not only holding a ladle of sewage, but also Sushui River's cry for help.

The innocent child pointed to the secretly discharged sewage in the culvert and told the adults that because of it, the well water was no longer drinkable and hair would fall out when washing hair. This young child actually has a bald head. What hangs on the branches are not verdant green leaves or piles of fruits, but thousands of colorful plastic bags fluttering in the wind. It looks so proud, and it is the misdeeds of human beings that make them so arrogant.

A stream of sewage pours into a pond of fish that has been worked so hard to raise, and in the end there is only a sigh from the breeder and a pond of dead fish.

Factories billowing with smoke, villages buried in sand and dust, and creatures in the sky and on earth displaced by human beings... "Song of Life - China Environmental Warning Education Large-scale Photography Exhibition" is open today The Military Museum of the Chinese Revolution opened. As the spokesperson of the devastated nature, more than 100 shocking photos scream to mankind.

The photography exhibition is a panoramic review of the China Environmental Protection Century Tour 10 years ago. Most of the photos are from the works of reporters from the China Environmental Protection Century Tour in recent years. Over the past 3,650 days and nights, hundreds of journalists have worked hard and hard, relying on their professional sensitivity and strong sense of responsibility to faithfully record the history of China's ecological and environmental changes with their own lenses and pens.

The heart-stirring photos are a warning that the earth, the home of mankind, has been destroyed to pieces by mankind itself. Wake up! Those saboteurs who are still obsessed with it.

The exhibition is divided into chapters such as Huaihe Scream, Yellow River Ballad, Yangtze River Ode, Green Variations, Blue Andante, Golden Ensemble, and Where Hope Is.

Walking towards the Mother River, I saw cracked ponds and dry land: the water used along the Yellow River has exceeded the carrying capacity of the Yellow River water resources, and there is a serious water shortage. From 1972 to 1998, the lower reaches of the Yellow River experienced dry flow for 21 years, and siltation in the main river channel increased. The "hanging river above the ground" in the lower reaches of the Yellow River is increasingly in danger.

Walking towards the Mother River, what you see is the artery of black water flowing raging into the Mother River: In recent years, the "fifteen small" polluting enterprises in the Yellow River Basin have developed rapidly, and the amount of sewage discharged into the main branches of the Yellow River every year Reaching 4.2 billion cubic meters, sewage is becoming increasingly serious, and many river sections are only filled with sewage.

The Yangtze River is also a tragic song. The endless stretches of yellow sand are crying and complaining: the green at the source of the Yangtze River is shrinking. According to statistics, more than 25,000 square kilometers of grassland have been degraded in the source area of ??the Yangtze River. Due to the influence of rats, 10% has been reduced to "black soil beach" type secondary bare land. Human activities are also aggravating the degradation of grassland. According to satellite remote sensing measurements, the pasture area of ??Qinghai Province is degrading at a rate of 2 million acres per year, while the number of livestock carried in Qinghai Province's pastures is increasing at a rate of 3% per year.

Many visitors were shocked by this photo: countless Tibetan antelope heads were piled together!

The Tibetan antelope is known as the "Plateau Elf" and lives in the "Third Pole of the World" - the uninhabited land of Hoh Xil on the Qinghai-Tibet Plateau. It is a national first-level protected animal. 50 years ago, there were nearly one million Tibetan antelopes living in Hoh Xil. When people discovered its amazing economic value (in the international market, a Tibetan antelope cashmere shawl was priced at US$11,000, and the highest price could even be sold for US$40,000). ), in the past few decades, the Tibetan antelope has been on the verge of extinction, with only 50,000 remaining. It is said that between 1990 and 1998, when poaching was most rampant, 20,000 Tibetan antelopes fell to poachers' guns every year. For the high profits of cashmere shawls, poachers are still taking desperate risks.

On Tianbao Mountain in Diqing, Yunnan, there is a large area of ??mountainous land where the trees have been cut down. Waist-high, blackened tree stumps stand silently on the green meadow like tombstones.

It was originally a well-preserved virgin forest. Although large-scale logging has been stopped at the end of the last century, who can tell clearly how many virgin forests Diqing has destroyed after more than 20 years of unscrupulous logging?

The seven major river systems of Haihe River, Liaohe River, Huaihe River, Yellow River, Songhua River, Yangtze River and Pearl River are all polluted to varying degrees.

One-third of the cities in my country have air quality exceeding Level 3 standards. Acid rain and sandstorms linger around us.

The situation in Wanli Sea is not optimistic either, with red tides arriving as scheduled every year. In the beautiful Bohai Bay, the turbid currents splash, and the oil floating on the sea is like a black torch that burns out the life in the ocean.

Ecological destruction is intensifying, with land degradation, soil erosion, lake shrinkage, and biodiversity declining. The ecological environment has become extremely fragile.

Qu Geping, who is in his late seventies, is one of the earliest advocates for environmental protection in China. The old man stopped and looked at each picture. He said emotionally: "China still has a long way to go to protect the ecological environment. The public should act quickly!" (Liu Shixin)

Water

——What can I do for you?

Number of views: Source: Author:

Water - the source of life for 2 billion people; water - the hope for the survival of all things in the world; water - the most desired goal of mankind. However, such precious and sacred water of life has been destroyed by human beings because of their selfishness and greed.

Slowly, slowly, there are more and more countries, provinces, municipalities and autonomous regions that are short of water in the world. Currently, there are *********** people in the world who do not have enough water. With the gradual development of scientific undertakings and the number of high-rise factory buildings, the water shortage problem has become more and more serious. With the destruction of mankind, the original blue "crystal ball" is no longer clear and blue, and is about to dry up.

Although 71% of the earth’s surface is covered with water, freshwater resources actually account for only about 2% of the earth’s total water, and the total amount of freshwater that can be utilized by humans only accounts for 100,000 of the total water on the earth. Three-thirds of the total fresh water storage accounts for 0.34%. It can be seen that there is not as much usable water on the earth as humans imagine. If it continues to be destroyed by humans, sooner or later it will disappear. Therefore, we should protect water resources and do our part to protect water resources.

Although I am still a 12-year-old primary school student, I want to use the sacred pen in my hand to call on everyone to protect water resources.

Water's self-narration

I am water, pure, beautiful, elegant and noble water. I come from the snow, I come from the mountains, slowly and slowly. It gently passes through the mountains, across the plains, and merges into the sea.

I am water, the crystal snow is my predecessor, the sweet rain is my brother, and the bitter tears are my sister. My footprints are all over the earth, and my arms caress every corner.

Only because of me, life will be so perfect; only because of me, everything in the world will be so perfect. I am not only a rich "nutrition" for the fields and a "growth agent" for the crops, but also a must-have for human beings. I am needed for washing rice and washing vegetables, and I am needed for washing and irrigating. I am the one who drinks when people are thirsty, I am the one who washes when they are dirty, and I am the one who uses them when they are in a hurry. But I am also the one who is constantly destroying things.

I have brought happiness to mankind, but why do humans treat me like this? I nurture the earth silently and selflessly. I am gurgling in the middle of the mountain, running happily in the middle of the grassland, and surging in the embrace of the sea. I am kind and loyal. I dedicate everything to human beings. Faced with the indifference and ruthlessness of human beings, I will get angry involuntarily and cause disasters. People can dominate all things, but they can destroy the ecological environment and human beings. Today, China is facing two major problems: First, Resource issues, and the second is environmental issues. Among them, China's per capita water resources are half of the world's per capita water resources. Among environmental issues, the degree of my pollution is self-evident. If I am "violated", it will affect the growth of aquatic organisms and domestic crops, increase the spread of diseases, and endanger human health. Therefore, protecting the environment is an urgent fact, and implementing a sustainable development strategy is an inevitable shortcut to accelerating socialist modernization. Humanity has only one home, please protect this only cradle.

Therefore, I hope to be cherished by humans, and even more, I hope to be protected by humans. Please stop, don't torment me anymore!

Where are the green mountains and green waters now?

Scenes of the past still emerge easily from time to time.

The water in my hometown in my memory is so beautiful! The smooth flow is as quiet as a picture, and it echoes with the green mountains, so it is as green as the mountains; some will form streams and can be seen everywhere. That is the water in my hometown.

When you reach out and touch it, it slips through your fingers, soft and refreshing. When I first arrived there, I went there every day to wash my face with that water. It was hot summer at that time, so my father and I swam in it. "Plop!" I jumped into the water with a sound, and all the fatigue was immediately washed away. The coolness spread all over my body, as if I was in heaven on earth.

Once again, five years later, my father and grandma and I came here again. As soon as we arrived at the river, we were stunned by what we saw.

I can hardly believe that this is the water in my hometown that I will never forget.

There is also the famous Xiangjiang River in Hunan.

My parents said that in the past, the water of the Xiangjiang River was very clear, and many people came to swim in the hot summer. People affectionately call it the "Green River".

However, now, the ancient Xiangjiang River has been swallowed up, and the surface of the river is full of plastics, medicine bottles, white pollution... emitting a disgusting stench. The Xiangjiang River, known as the "green river", has become a "dead river".

Suddenly, I understood that people today are blindly pursuing development and ignoring the importance of protecting the environment and protecting water resources.

The whole river echoed with the sigh of the river: "People have destroyed my body!"

Alas! Where are the green mountains and green waters now?

If you lose water...

People, people!

What would you drink if you lost your water? What is used to irrigate every inch of land and what is used to nourish every blade of grass? If there was no such beautiful water, where would the timeless saying of Su Shi come from? If there is no water, where would everything in the world be?

When we face such water, will you still praise its beauty and lament its vitality? Faced with the facts before us, isn't it enough to sound the alarm and awaken people's awareness of water problems?

As the saying goes: "Only when you have lost it do you know how to cherish it!"

People, do you really want the last drop of water to become the tears of human heartbreak, regret and awakening? Please don’t understand how precious it is only after you lose it. By then, I’m afraid it will be useless to regret it.

Please cherish every drop of water! Don't mess with it anymore.

Just think of this as a reward for giving water!
