不乱砍滥伐的英语作文初中

As a middle school student,it is essential to understand the importance of preserving our natural environment.Deforestation,which involves the excessive and unregulated cutting down of trees,can have devastating effects on the ecosystem.In this essay,we will discuss the consequences of deforestation and the importance of sustainable forestry practices.IntroductionThe Earths forests are a vital part of our planets life support system.They provide habitats for countless species,regulate the climate,and play a crucial role in the water cycle.However,due to human activities,deforestation has become a significant issue, threatening the balance of our ecosystems.The Impact of Deforestation1.Loss of Biodiversity:Forests are home to a vast array of plant and animal species. When trees are cut down,these species lose their habitats,leading to a decline in biodiversity.This loss can disrupt the food chain and lead to the extinction of species that are crucial for maintaining the balance of the ecosystem.2.Climate Change:Trees absorb carbon dioxide,a greenhouse gas that contributes to global warming.When forests are cut down,the carbon stored in the trees is released back into the atmosphere,exacerbating climate change.3.Soil Erosion:Tree roots help to hold the soil together.When trees are removed,the soil becomes more susceptible to erosion,which can lead to landslides and the loss of fertile land.4.Disruption of Water Cycle:Trees play a role in the water cycle by absorbing and releasing water.Deforestation can disrupt this cycle,leading to changes in rainfall patterns and the potential for droughts.Sustainable Forestry PracticesTo mitigate the effects of deforestation,it is crucial to adopt sustainable forestry practices. These include:1.Selective Logging:Instead of clearcutting,selective logging allows for the removal ofa limited number of trees while leaving the forest structure intact.This method helps to maintain the health of the forest and its biodiversity.2.Reforestation:Planting new trees to replace those that have been cut down is an essential part of sustainable forestry.This practice helps to restore the forests ability to provide habitat and regulate the climate.munity Involvement:Engaging local communities in the management of forests can lead to more sustainable practices.Local people often have a deep understanding of the forest and its importance to their livelihoods.4.Regulation and Enforcement:Governments play a crucial role in regulating forestry practices and ensuring that they are sustainable.Strong laws and effective enforcement are necessary to prevent illegal logging and promote responsible forest management.ConclusionAs future stewards of the Earth,it is our responsibility to protect our forests.By understanding the consequences of deforestation and promoting sustainable forestry practices,we can help to ensure that our forests continue to thrive and provide the benefits that are essential for the health of our planet and its inhabitants.It is time for us to act,not only for our own sake but for the sake of the countless species that depend on these vital ecosystems.。

Today, most records of biodiversity are often in the form of photos, videos, and other digital records. Though they are useful for detecting shifts in the number and variety of species in an area, a new Stanford study has found that this type of record is not perfect.“With the rise of technology it is easy for people to make observation s of different species with the aid of a mobile application,” said Barnabas Daru, who is lead author of the study and assistant professor of biology in the Stanford School of Humanities and Sciences. “These observations now outnumber the primary data that comes from physical specimens(标本), and since we are increasingly using observational data to investigate how species are responding to global change, I wanted to know: Are they usable?”Using a global dataset of 1.9 billion records of plants, insects, birds, and animals, Daru and his team tested how well these data represent actual global biodiversity patterns.“We were particularly interested in exploring the aspects of sampling that tend to bias (使有偏差) data, like the greater likelihood of a citizen scientist to take a picture of a flowering plant instead of the grass right next to it,” said Daru.Their study revealed that the large number of observation-only records did not lead to better global coverage. Moreover, these data are biased and favor certain regions, time periods, and species. This makes sense because the people who get observational biodiversity data on mobile devices are often citizen scientists recording their encounters with species in areas nearby. These data are also biased toward certain species with attractive or eye-catching features.What can we do with the imperfect datasets of biodiversity?“Quite a lot,” Daru explained. “Biodiversity apps can use our study results to inform users of oversampled areas and lead them to places – and even species – that are not w ell-sampled. To improve the quality of observational data, biodiversity apps can also encourage users to have an expert confirm the identification of their uploaded image.”32. What do we know about the records of species collected now?A. They are becoming outdated.B. They are mostly in electronic form.C. They are limited in number.D. They are used for public exhibition.33. What does Daru’s study focus on?A. Threatened species.B. Physical specimens.C. Observational data.D. Mobile applications.34. What has led to the biases according to the study?A. Mistakes in data analysis.B. Poor quality of uploaded pictures.C. Improper way of sampling.D. Unreliable data collection devices.35. What is Daru’s suggestion for biodiversity apps?A.

飞逝的巨礁其他学科知识

飞逝的巨礁其他学科知识The topic "The Vanishing Reefs and Other Disciplinary Knowledge" explores the alarming decline of coral reefs around the world and the interconnectedness with various academic disciplines. Coral reefs are not only incredibly biodiverse ecosystems, but they also provide numerous ecosystem services such as coastal protection, fisheries, and tourism.From a biological perspective, the loss of coral reefs has devastating consequences for marine life. Coral polyps, which are the building blocks of reefs, provide a habitat for a wide range of species, including fish, crustaceans, and mollusks. The decline in coral reefs leads to a loss of habitat and disrupts the delicate balance of the marine ecosystem.From an environmental science standpoint, the decline of coral reefs can be attributed to a combination of factors. Climate change, specifically rising ocean temperatures and ocean acidification, poses a significant threat to coral health. Increased carbon dioxide levels in the atmosphere lead to ocean acidification, which weakens coral structures and makes them more susceptible to bleaching.Additionally, pollution, overfishing, and destructive fishing practices also contribute to reef degradation.Geographically, coral reefs are found in tropical and subtropical regions around the world. Understanding the distribution and characteristics of coral reefs requires knowledge of physical geography and oceanography. Factors such as water temperature, salinity, and nutrient availability influence the growth and health of coral reefs.Sociologically, the decline of coral reefs has implications for coastal communities that rely on them for their livelihoods. Fishing communities that depend on coral reefs for sustenance and income are particularly vulnerable. The loss of coral reefs can lead to food insecurity and economic instability, exacerbating social inequalities.In conclusion, the vanishing reefs highlight the interconnectedness of various academic disciplines. To effectively address the decline of coral reefs, a multidisciplinary approach is necessary, involving biology, environmental science, geography, and sociology. Only through a holistic understanding of the issuecan we work towards sustainable solutions and the preservation of these invaluable ecosystems.中文回答:题为“飞逝的巨礁和其他学科知识”的主题探讨了世界各地珊瑚礁的惊人衰退以及与各种学科的相互关系。

Agriculture is the backbone of any society, and crops are the lifeblood of this vital sector. In high school, we learn about the importance of various crops and their roles in sustaining life and driving economies. Here is a detailed essay on the subject:Title: The Importance of Crops in AgricultureCrops are the plants that are cultivated by humans for food, animal feed, fiber, and other purposes. They are the foundation of agriculture, which is the practice of cultivating plants and raising animals to meet the needs of a growing population. Without crops, life as we know it would not be possible.There are several types of crops, each with its own unique characteristics and uses. The most common types include cereal crops, legumes, root crops, and cash crops.1. Cereal Crops: These are the staple food crops that provide the majority of the worlds food supply. They include wheat, rice, corn, and barley. These crops are rich in carbohydrates and are essential for providing energy to the human body.2. Legumes: Legumes are plants that produce seeds in pods. They include beans, peas, lentils, and peanuts. Legumes are an excellent source of protein and are often used as a meat substitute in vegetarian diets.3. Root Crops: Root crops are plants that are grown for their edible roots or tubers. They include potatoes, carrots, beets, and sweet potatoes. These crops are rich in vitamins and minerals and are an important part of a balanced diet.4. Cash Crops: Cash crops are plants that are grown for sale rather than for personal consumption. They include cotton, coffee, cocoa, and sugar cane. These crops are often grown in large quantities and are a significant source of income for many farmers.The cultivation of crops requires careful planning and management. Farmers must choose the right crops to grow based on factors such as climate, soil type, and market demand. They must also ensure that their crops receive adequate water, nutrients, and protection from pests and diseases.Modern agricultural techniques have greatly improved crop yields and efficiency. The use of fertilizers, pesticides, and genetically modified seeds has allowed farmers to produce more food with less land and labor. However, these practices have also raised concerns about environmental impact and food safety.In conclusion, crops are an essential part of human life and play a crucial role in agriculture. They provide food, clothing, and income for billions of people around the world. As we continue to face challenges such as population growth and climate change, it is important that we continue to innovate and improve our agricultural practices to ensure a sustainable and secure food supply for future generations.。
马蝇效应英语作文

马蝇效应英语作文The Butterfly Effect: A Profound ExplorationThe concept of the butterfly effect, first introduced by meteorologist Edward Lorenz, has captivated the minds of scientists, philosophers, and the general public alike. This intriguing phenomenon, where a seemingly insignificant change in one part of a complex system can lead to dramatic and unpredictable consequences in another part, has far-reaching implications that extend beyond the realm of weather forecasting.At the heart of the butterfly effect lies the inherent complexity of the world we live in. Our universe is a tapestry of interconnected systems, each with its own intricate web of variables and feedback loops. The flapping of a butterfly's wings in one corner of the globe can set in motion a chain reaction that ultimately influences the weather patterns thousands of miles away. This realization challenges our intuitive understanding of causality and forces us to reconsider the delicate balance that underpins the natural order.One of the most remarkable aspects of the butterfly effect is its ability to transcend the boundaries of the physical world. Itsprinciples can be applied to a wide range of disciplines, from economics and sociology to psychology and even human relationships. In the realm of finance, for instance, a seemingly minor shift in market sentiment or a single trading decision can ripple through the global economy, leading to seismic shifts in stock prices, exchange rates, and the fortunes of individuals and corporations.Similarly, in the social sphere, a single act of kindness or a thoughtless remark can have far-reaching consequences, altering the trajectory of human interactions and relationships. The way we treat our family members, colleagues, or strangers can set in motion a series of events that profoundly impact the lives of others, often in ways we could never have anticipated.The butterfly effect also has significant implications for our understanding of the human condition. It challenges our notions of free will and individual agency, forcing us to confront the reality that our actions, no matter how small, are inextricably linked to the larger tapestry of existence. This realization can be both humbling and empowering, as it encourages us to approach our lives with a greater sense of mindfulness and responsibility.Moreover, the butterfly effect has inspired a deep fascination with the concept of chaos theory, which explores the underlying patterns and unpredictability inherent in complex systems. Mathematicians,physicists, and computer scientists have devoted countless hours to unraveling the mysteries of chaotic systems, seeking to understand the delicate balance between order and disorder that shapes our world.In the realm of science fiction, the butterfly effect has become a powerful metaphor for exploring the consequences of time travel and alternate realities. From Ray Bradbury's seminal short story "A Sound of Thunder" to the mind-bending narratives of movies like "Looper" and "Inception," the idea of a single change in the past rippling through time has captured the imagination of writers and filmmakers alike.Ultimately, the butterfly effect serves as a powerful reminder of the interconnectedness of all things. It challenges us to approach the world with a deeper sense of humility and respect, recognizing that our actions, no matter how small, have the potential to create profound and lasting change. By embracing this understanding, we can strive to be more mindful, responsible, and empathetic citizens of the world, working to create a future that is more resilient, sustainable, and just.。

南冰洋温度上升一摄氏度,会有哪些变化?

W hat changes are when you warmthe Antarctic Ocean just 18?奈冰#溫度&度,含-哪些01?By Vera Jonesj^^^Lfter warming a natural seabed in the Antarctic Ocean by just 1"or 2 ", researchers observed massive impacts on a marine ecosystem, as growth rates nearly doubled. The results of what the researchers call 4<the most realistic ocean warming experiment to date" reported in Current Biology on August 31 show that the effects of future warming may far exceed expectations.“I was quite surprised," says Gail Ashton of the British Antarctic Survey and Smithsonian Environmental Research Center, ul wasn#t expecting a significant observable difference in communities warmed by just 1° C in the Antarctic. I have spent most of my career working in temperate climates where communities experience much greater temperature fluctuations(波动)and wasn’t expecting such a response to just 1°C of change."Predicting how organisms and whole communities will respond to climate change in the future re mains a major challenge. So, Ashton and her colleagues decided to actually warm an area of seabed around the Rothera Research Station and watch what happened. They used heated settlement panels (面板)to warm a thin layer of water by 1°C or 2°C above the surrounding temperature. Those increases in global temperature are expected within the next 50 and 100 years, respectively.The experiment showed that with a 1°C increase in temperature, a single pioneer species of protozoan(原生 动物)increased in number like crazy. That one species finally dominated (支配)the community, driving a reduction in overall species diversity and evenness within two months.The responses of organisms to a 2° C rise in tem perature were much more variable . Growth -rate responses to warming differed among species, ages, and seasons. Species generally grew faster with warming through the Antarctic summer. However, different responses among species were observed in March, when both food availability for suspension feeders and surrounding temperature declined , the researchers report.The researchers said the findings suggest that climate change could have even greater effects on polar marine ecosystems than had been anticipated. As the planet warms, there will be winners and losers.The researchers say they now plan to expand the use of this technology to investigate the response to warming in other locations and communities, including the Arctic.2018.4疯狂英语(读写版)51。

Four Laws of Ecology中英对照

Four Laws of Ecology1 In broad outline,there are environmental cycles which govern the behavior of the three great global systems:the air,the water,and the soil.Within each of them live many thousands of different species of living things.Each species is suited to its particular environmental niche,and each,through its life processes,affects the physical and chemical properties of its immediate environment.1概括来讲,地球的三大系统—空气、水和土壤的行为由环境循环所决定。
每个系统中都生活着成千上万个不同物种的生物,每个物种都有与之相适宜的独特的环境生位,并且每一物种,在其整个生命历程中,都影响着它的周边环境的物理和化学特性。
2 Each living species is also linked to many others.These links are bewildering in their variety and marvelous in their intricate detail.An animal,such as a deer,may depend on plants for food;the plants depend on the action of soil bacteria for their nutrients;the bacteria in turn live on the organic wastes dropped by the animal on the soil.At the same time.the deer is food for the mountain lion. Insects may live on the juices of plants or gather pollen from their flowers.Other insects suck blood from animals.Bacteria may live on the internal tissues of animals and plants.Fungi degrade the bodies of dead plants and animals.All this,many times multiplied and organized species by species in intricate,precise relationships,makes up the vast network of life on the earth.2每个生物物种也与许多其他的物种相联系。

EU Slashes Growth Forecasts and Warns Over Brexit
The European Commission slashed its growth forecasts for all the euro region’s major economies from Germany to Italy and warned that Brexit and the slowdown in China threaten to make the outlook even worse.
The European Union’s executive arm delivered a downbeat report on Thursday that shaved a whole percentage point off its2019projection for Italy,now seen with minimal expansion of just0.2percent for the whole year.Officials in Brussels warned that the region’s outlook faces“substantial”risks.
The gloomier forecasts reflect more pronounced weakness in the region,which stumbled at the end of2018as political instability continued to rock Italy,violent protests in France depressed output,and Germany’s car industry struggled to rebound from changes in regulation.Global trade uncertainty and a
sharper-than-expected slowdown in China also pose external risks to the economic outlook.
In its forecasts,the commission sees the19-nation euro-area economy expanding1.3 percent this year down from1.9percent projected in November.For2020,it sees growth of1.6percent,down from1.7percent forecast earlier.
Italy’s downward revision was the starkest,with the commission seeing growth slowing to0.2percent--the lowest in the bloc by far--compared with its previous forecast of1.2percent.The lowered outlook comes two months after Rome and Brussels reached a compromise over Italy’s deficit target and will likely make it more difficult for the populist coalition to carry out its expansive spending plans.
“We need to watch certain situations and the situation in Italy as far as growth is concerned is much worse with0.2percent,which is quite significant,”EU Economic Affairs Commissioner Pierre Moscovici said in an interview with Bloomberg Television from Brussels.
Clouds Gathering
"Much of the euro area’s loss of growth momentum can be attributed to fading support from the external environment,including slower global trade growth and
high uncertainty regarding trade policies,"the commission said."However,there have also been a number of domestic factors at play,"it said,pointing to social tensions and budget-policy uncertainty in some countries,as well as weakness in the car industry.
Clouds on the horizon are also getting darker,the commission said.“In the U.S.,the risk of an abrupt fiscal tightening appears to have increased,especially for2020,”according to the report.“The Chinese economy might be slowing more sharply than anticipated while many emerging markets are still vulnerable to sudden changes in global risk sentiment.”
For the European Union,Brexit remains a source of uncertainty,the commission said.
An increasingly anemic economy will test the resolve of the European Central Bank in sticking to its plans to gradually pare back its crisis-era stimulus.ECB policy makers already walked a fine line in December by downgrading economic forecasts at the same time as ending net asset purchases that have helped buoy euro-area demand.
On inflation,the commission cut its2019euro-area forecast to1.4percent,down from1.8percent in earlier projections.The ECB aims to get inflation to just below2 percent over the medium term.。
