After watching the first documentary about climate change in Taiwan Province Province, my mood became very heavy. Although people have paid more and more attention to environmental awareness in recent years, I naively think that this is not so bad, because I have not personally experienced the direct impact of the greenhouse effect. But after reading it, I found myself wet all over!

The earth, our beautiful home, has been broken under repeated destruction.

When Armstrong landed on the moon, he looked back at the earth. He said he didn't know the earth was so beautiful. The earth has a history of 4.6 billion years, and human beings have only appeared for thousands of years, but it almost ruined her beauty. The earth is beautiful, but while human civilization is flourishing, it is also dying. The earth has nurtured human beings for thousands of years, but we are like children who bite the hand that feeds them, constantly hurting our mothers. At first, she was tolerant, letting human beings get whatever they wanted, but human beings pushed their luck and became more and more fierce, forcing our mother to get angry at last.

The terrible mudslide caused by the rainstorm and sandstorm suddenly made people seriously allergic. Sudden climate changes have caused freezing floods everywhere, and global warming has led to the extinction of animals and plants. Nature, which once silently endured everything, fought back under the long-term destruction of the environment by human beings.

In the past two years, the weather has become very strange, and there are illusions everywhere-it is a day when Beijing is in darkness, as if it were a windy night; Severe sandstorms have enveloped Australian cities, and the amount of sand is amazing. An old man said that he had lived for 72 years, and this was the first time he met him. A number of strong typhoons in the Philippines took turns to go into battle, causing many lives to disappear in the eyes of the public, causing serious loss of life and property; The snowfall in high-latitude countries has hit record highs, but the temperature has hit record lows; In some countries, the temperature is horribly high, and droughts and heavy rains appear alternately, in a cycle. ...

After reading plus or minus 2 degrees Celsius, there were scary scenes in front of me, and I was very scared. Although Beijing is not a coastal city, it is also very likely to be submerged by melting icebergs, so I decided to start doing my best to protect the earth: blowing less air conditioners in summer, using bicycles or walking in nearby places to minimize carbon dioxide emissions; Plant more plants to green the environment and publicize the concept of environmental protection to influence friends and relatives around to be kind to the earth; Do a good job in garbage sorting, increase resource recovery and the use of renewable energy. In my opinion, the work of protecting the earth should start from individuals and be implemented in daily life, even if it is a small action, which is the most responsible performance.

But many people always think that their meager strength can't change the facts, and even think that the extinction of the earth is impossible. But if everyone holds such a mentality, who will protect the earth?

Mother told me: In fact, not only environmental protection can save the earth, but also the ancients mentioned a truth more than once, that is, everything comes from thinking. In life, if you are less jealous, less greedy and less self-righteous, you are saving the earth! If you share this "plus or minus 2 degrees" again, help your mother do housework and make a disciple rule, you will save the earth!

Mother Earth is the land where we live together and provides us with abundant resources, but we are ungrateful to destroy it. Now, maybe we can't let it return to its former prosperity, but at least we should control the global temperature rise within 2 degrees.

The life and death of civilization are in our hands.

The film is divided into seven paragraphs. The first paragraph combs the amazing global climate change phenomenon in the past six months. In the second paragraph, from the scientist's point of view, I quote the reports of Academia Sinica and IPCC to explain why these phenomena occur. In the third stage, Taiwan Province Province must face several truths, including that Taiwan's population density is the second in the world, only lower than that of Bangladesh, and many poor people are forced to live in places unsuitable for human habitation, which is very dangerous. The second truth that Taiwan Province Province must face is that the land erosion rate in Taiwan Province Province is very high, with an annual rate of 2%, ranking among the top ten in the world. Third, Taiwan Province Province is located on the typhoon chain island in Asia. There are three or four typhoons every year. In other words, when global warming becomes more and more serious and the extreme phenomena of rainstorm and storm become more and more obvious, the disaster situation in Taiwan Province Province will be more serious than that in other Asian countries or regions such as Japan and China. In the future, typhoons will become stronger and stronger and rainfall will become more and more extreme. Drought will be followed by heavy rain, and heat wave will be followed by cold winter. The land erosion rate of residents in Taiwan Province Province will become more and more serious, and Morakot will not be the only one.

The documentary also compares the preparedness of Taiwan Province Province and the Netherlands for global warming. 1953, the Netherlands experienced a disaster similar to Morakot. As a result, the Netherlands established a world-famous Millennium water conservancy project that no one can surpass in history. At that time, it was called "Millennium flood control standard". But the Dutch officially realized five years ago that under climate change, this "Millennium" could not be faced for even 20 years. As a result, the Netherlands has launched a new land planning, with a budget scale exceeding the national defense budget, returning the original land to the sea, the sea, the river and the water for a living, and inventing floating houses to prepare for the new earth ecology after the sea level rises in 2035.

Five months after the documentary and 20 10 1 morakot, we returned to the edge of the forest, which was called purgatory during the typhoon. We see that the riverbed is still silted up higher than roads and bridges, and we are very worried about the efficiency of the government. At the same time, combined with the research of professors and students from the Institute of Hydraulic Engineering of National Taiwan University, the documentary filmed Shimen Reservoir in Taiwan Province Province in the air. Due to previous storms, including this Morakot storm, Zengwen Reservoir and Nanhua Reservoir in the south were silted up. Five years ago, the typhoon in Zhi Tao silted up Shimen Reservoir, making the reservoir's ability to resist extreme rainfall weaker and weaker. Take Shimen Reservoir in Taipei as an example. At present, its limit capacity is only 1, 500 mm. In the future, as long as the rainfall breaks 1 500mm, especially if the rainfall drops suddenly in a short time, Shimen Reservoir will even have a major dam-break crisis. The so-called 1500mm is only a little more than half of the rainfall of Mount Ali in Morakot, and it is also the total rainfall measured in Han Xi, Yilan last September.

This documentary hopes to attract all audiences who are concerned about climate change in Taiwan Province Province. We always expect good leaders, but when a democratic country does not have good citizens, the elected national leaders are unlikely to make major changes in policies. Therefore, the documentary hopes that at least millions of people in Taiwan Province Province can watch the positive and negative second-degree C documentary, so as to unite the truly strongest consciousness of Taiwan Province Province on the island and make brave changes.

At the end of the documentary, a dialogue with an Indian girl at the United Nations in 2009 was quoted. The girl stood in front of the representatives of various countries to the United Nations and said to the powerful international leaders, "I hope you will make changes to the earth. You don't want me to come back and question you when I grow up. What did you do when you had power? 」

The news has been reporting the natural and man-made disasters that are happening all over the world, but these misfortunes are too far away from me, and everything seems unreal, so it will naturally fade away. Listening to the emotional narration of the narrator, the screen is full of fragments, plus sad background music; Finally, this movie touched my heart and gradually pulled me back from daydreaming to reality. Looking at the abnormal changes in the weather around the world, the balance of spring, summer, autumn and winter is slowly out of balance, and I finally understand that mankind is about to die.

Even if the weather rises, no matter how polluted the earth is, the animals and plants on the earth will become extinct before her. Without us, the earth would still be spinning and endless. A few years later, due to the extinction of human beings, the factors that pollute the earth no longer exist, but they can breed more vitality. However, since it has appeared here, it is still possible to mend it when the temperature is still under control at this stage. Don't wait until the temperature rises, wild animals are on the verge of extinction, species are forced to migrate, and human beings have a crisis of survival before they know regret.

You don't have to wait until the North Pole melts in ten years. Just now, there was a lot of ice melting in the Arctic. Seeing polar bears devour their own kind, even the coldest people will be infected by their behavior. The symbol of northern species has gradually lost, who is sure that the next one will kill each other? Isn't the next difficulty a person?

We probably all think that spring is short, summer is long, autumn is short, winter is long, winter is colder and summer is hotter. We also heard about the most terrible drought and the fire that followed, the most amazing rainstorm and the flood caused by it. The former is because the earth is warming, and so is the latter.

The film says that the scale of human existence is only between plus and minus 2 degrees. If the earth's temperature drops by 2 degrees, human physical fitness will not be able to adapt. If the earth's temperature rises by 2 degrees, many small island countries will die first, and then the coastline of the mainland will be swallowed up step by step, the Yellow River Delta in China, that is, Tianjin and even Beijing; Yangtze River Delta, that is, Shanghai and its surrounding areas; The Pearl River Delta with the most developed economy and the most densely populated population in China, namely Guangzhou and its surrounding areas, will bear the brunt. As the temperature rises above 6 degrees, the global species, including plants, animals and all kinds of marine life on the mainland will be extinct. Humans-as the culprit, nature is also among them.

The film begins with the ticking of the doomsday clock, and the director chenchen Wenxi presents a picture of the countdown of life on earth. How long this countdown is depends entirely on people's actions. In fact, this countdown has already started, and it is very urgent. It's just that human beings hide their ears, and the lessons are not strict enough and not popular enough. According to science, there is a lag problem, that is, the impact of human actions on the earth will appear in the next 10 year. In other words, even if people around the world don't need electricity in the next year, this deterioration will continue and will not improve in the short term. Of course, even this assumption is completely unrealistic. What is the realistic approach? A subtitle appeared in the film, which was signed by a monk in Taiwan Province Province. He wrote: "Saving the earth requires us to open up new sources and cut costs", that is, the development and utilization of new energy, energy conservation and environmental protection. The latter, how difficult!

Now it's a life-and-death game. How careless we are.

I wonder if Armstrong ever said that the beauty of the earth from space is like a tear.

In August, 2009, Typhoon Morakot hit Taiwan Province, which brought amazing rainfall. The torrential rain for several days caused serious landslides, mudslides and dam breaches ... which caused the biggest disaster in South Taiwan Province Province in recent 50 years. Not only did it cause hundreds of casualties, but the rolling floods also destroyed many homes, and the losses in all aspects were incalculable. As a result, global warming and climate anomalies after the "August 8 typhoon" have become the most concerned environmental problems. Recently, the teacher showed us the movie "plus or minus 2 degrees Celsius". After reading it, I felt a lot in my heart.

It is mentioned in the film: Since the industrial revolution, due to the extensive use of energy, the emitted CO2 has far exceeded the natural absorption rate, so the greenhouse effect has become more and more serious, and the global temperature has been rising all the way, leading to climate anomalies in all countries of the world. For example, in Beijing, it should have been sunny, but it was like night because of an unprovoked downpour; The Philippines has just been hit hard by the last typhoon, and its home has not been rebuilt. Several typhoons followed one after another, and typhoons became a lingering dream of local residents. In addition, many island countries are gradually disappearing because of the rising sea level! These climate anomalies are all caused by our excessive use of energy and our failure to cherish the environment. For example, cars and locomotives emit a lot of carbon dioxide, factories emit black smoke, and hillsides are reclaimed indiscriminately. The catastrophe brought by "global warming" will inevitably follow.

In addition, we also see that this catastrophe of human beings not only endangers our survival, but also endangers the ecology of the animal kingdom: hot and cold weather leads to the sudden death of fish; The arctic ice has melted a lot, and polar bears have been swimming around for food, and they have drowned without finding a habitat; What's more, some polar bears eat their cubs because they can't find food. This terrible picture is really embarrassing. Many animals are on the verge of extinction due to the rapid changes in the environment.

The film also points out that residents of Taiwan Province Province are the first refugees of global warming. I think this is a fact that we must face. So we must have a sense of crisis and make some changes together. If everyone has the determination to protect the earth, it is not impossible to save it. From now on, let's work together to save energy and reduce carbon, do environmental protection, cherish the natural ecology, and make the future earth still livable. After all, the fate of all living things on earth is in everyone's hands.

It is recommended to extract it comprehensively.

Add some transitional sentences between paragraphs. Do it.

So the teacher couldn't find out.
