People have been displaced by herds of animals for their own sake. It's not a false fantasy, it's a bloody fact.Once upon a time, many animals and plants in the world were destroyed, and so many animals and plants were endangered. Why? This is all because human beings are cutting trees and destroying the ecological environment, which is the root cause.Land resource is one of the three major geological resources (mineral resources, water resources, land resources) and is the most basic resource and labor object of human production activities. Human land use degree reflects the development of human civilization, but also cause direct damage to the land resources, the main show is unreasonable reclamation plant caused by soil erosion, land desertification, soil secondary salinization and soil pollution, soil and water loss is particularly serious, but facing the world today and a serious crisis. It is estimated that the amount of topsoil in the world's arable land is about 23 billion tons per year.Some argue that acid rain is a silent crisis, and the worst environmental threat we've ever seen, an invisible enemy. This is not alarmist. As industrialisation and energy consumption increase, acid emissions are also increasing, and they enter the air, forming acid rain through a series of functions.Although the red tide has been around since ancient times, with the rapid development of industrial and agriculturalproduction, water pollution is becoming more and more serious, and the red tide is becoming more and more serious. Since the first report in 1933, there have been 194 large-scale red tides since 1994, including only four in the 1960s and 157 in 1990. Oil pollution is very harmful to water quality and aquatic life. The oil that floats on the surface of the water can quickly spread, forming an oil film, which prevents the surface from contacting with air, and reduces the dissolved oxygen in water. Oil contains polycyclic aromatic hydrocarbons, which can be harmful to human health after the accumulation of aquatic organisms. Sulfur dioxide is mainly produced by burning fuels such as coal and fuel, followed by nature, such as volcanic eruptions and forest fires. Sulfur dioxide is strongly irritant to the conjunctiva and upper respiratory tract of the human body, but can be damaged by inhalation tube and can cause bronchitis, pneumonia and even pulmonary edema respiratory paralysis. In the short term, the mortality rate of the elderly or chronic patients with the concentration of 0.5mg/m3 air is higher and the concentration is higher than 0.25 mg/m3, which can aggravate the condition of the respiratory diseases. The number of people with prolonged exposure to 0.1 mg/m3 of air was increased. In addition, sulfur dioxide can cause corrosion, peeling, fading and damage to metal materials, housing construction, cotton spinning fabrics, leather paper and other products. It can also turn yellow or even die.Protecting the environment is everyone's responsibility.高一必修二英语单元作文2On the night of a full moon, the mother of the earth sighed and asked, "what's wrong with you mother earth?"

In some places we can't see fish swimming in the river or trees on the hills. Bird there is less and less fresh water in the world.Some people even have no clean water to drink. So I think we must do something to protect the environment. But what can we do? How to protect our environment? For example, we can go to school on foot or by bike instead of taking a car. We had better use shopping basketbets instead of plastic bags when we go shopping. We should use both sides of the paper when we write. Do't use paper cups. At our school dinning room, use our own bowls and chopsticks instead of disposable ones. We can reuse the water and save the electricity.In a word, if everyone pays more attention to ourenvironment, there will be less pollution and our life will be better."There is only one earth", I hope everyone will protect our environment well.高一必修二英语单元作文4In an interview with the Nobel Prize to award conference, a reporter to interview one of the scientists, asked: "do you think of in which university and which lab knowledge's most important to you?" Scientists answer: "kindergarten/" other scientists also agree that in the kindergarten learn the knowledge of the most important, where the teacher taught us to love the nature, observing nature. This reminded me of a text I had learned in sixth grade, called "just one earth." Yes, because there is only one earth, so we, as children and children of the earth, should be more protective of our mothers. Society always advocates the love of nature and the environment, but there are several people who can really do it. Do we really want to wait for our mother to be blackened before we wash her? I thought it was too late.One gutter stinks, road street, the road is full of garbage, oneby one old dirty trash can shake with the wind, forest by people are eating... In the face of all this, people should explain. To be honest, sometimes, I felt some news in the TV do very hypocrisy, take ZhaoAn news, the wind a leader to lead the masses to clean a gutter, news is the leading up to the hero, still have a lot of gutter ZhaoAn, everywhere, has also been plagued by people of pick up is always take the gutter ZhaoAn news, I am not in denial ZhaoAn news, just some news very boring. The protection of the environment cannot always be spoken by words, not actual actions; Some people unknown to contribute to the environment, work hard, if I were a reporter, I'd rather go to shoot them, with their deeds to call for people, to make our environmental consciousness enhancement. With our neighbors, for its part, the environmental protection consciousness is bad enough, in the courtyard of their house has a ditch, has been rotten for many days, sometimes affects all of us can't sleep, but they still pretend as if nothing happened, originally clean up early on, all things that he did not, but... And we told them that they didn't want to say anything. T o protect a solemn statement, deeply loves the nature of the first measures, we must enhance our environmental protection consciousness, consciousness enhancement, the people will throw, throw, destroyed. At that time, don't say that the edict was happy, and the whole nation would be happy.The scientists in this material also say that in the kindergarten, they have learned how to love nature, and children understand the truth, don't the adults understand? Love nature, protect the environment, is the duty of the whole country people, hope everybody can rise up to protect the earth, protect mother! Bid farewell to the dirty of the past and look forward to future clean!高一必修二英语单元作文5Live in my house too, west town, in front of my house have a long big ditch, if before, I will lift up his thumb kua it, but now, I to them for it.I had been playing at this ditch since I was a child, and when I was five or six, my father often took me to the ditch to play with water. Every summer, the ditch water full, the fish in the water in teams, to chase, weeds on both sides of the ditch is thick, the duck likes to wear to wear in the grass, as if to hide and seek, every day early in the morning, when the flashing dew on weeds, the duck is singing. The clear gutter flutter eastward, and it seems to be singing merrily, and every afternoon it is a paradise for our little children.Later, in imperceptible in, the ditch water become dirty, smelly, can't see even a small fish, groove face floated from time to time some of the animal's body, all kinds of plastic bags, rod, leaves cans... It turns out that in recent years, so more and more sand industrial park of the new factory, the factory waste water directly into the ditch without being cleaned, people also casually to ditch the trash, throw bricks... Now, on both sides of the ditch lush reeds by some cut to feed the sheep, and the remaining red willow also few, isn't here birds build nests, the duck is not here to sing, sometimes the ditch floating around, large and small, dead fish.Ah! Hometown, how beautiful is your original clean ah, but now you became a contaminated town, I loudly cries from the bottom of my heart: "people, wake up, protect the ecological, environmental protection, obligatory. Only in this way, can save water, save home, save the planet, save ourselves."Today, ignorance of humans, endless mirror to factory wastegas, waste liquid and smoke a lot of emissions into the earth mother's skin, blood, released into the earth mother feed in the milk of humans, only emissions into the atmosphere every year all over the world lead, mercury and cadmium, respectively is 200 tons, 11000 tons and 11000 tons, the clouds smoke, waste gas, the thick liquid waste and sewage, bared his teeth like contemplating the cancer cells to came to me and hit my body health, and even to protect the earth mother and our ozone layer veil torn two tunnels, ultraviolet relentlessly burn the earth mother's skin, cause serious damage to our survival. You see, we often think of metaphor is the sky blue sea, white clouds, the analogy is white cotton, the grass as green carpet, and the actual is all grey, these changes in the environment, make me sad, let me to tears.Human clothing, food, shelter, and practice are all dependent on the gift of nature. The atmosphere, the forest, the lake sea are all the conditions that people depend on. We humans should be awake, destroying the natural environment, which is the equivalent of destroying our homes and creating hunger. Let us act, my friends! Protect the environment, be duty-bound!。
