Greenhouse effect: also known as the "flower house effect", is a common name for the atmospheric insulation effect. The atmosphere can make the solar short-wave radiation reach the ground, but the long-wave thermal radiation released from the surface is absorbed by the atmosphere, so that the temperature of the surface and the lower atmosphere increases, because its effect is similar to that of a greenhouse for cultivating crops, so it is called the greenhouse effect.

If this effect were not present in the atmosphere, then the surface temperature would drop by about 33 degrees or more. On the other hand, if the greenhouse effect continues to intensify, the global temperature will continue to rise year by year. The greenhouse effect is mainly caused by the excessive burning of coal, oil and natural gas in modern industrial societies, and the emission of large amounts of exhaust gases, which release a large amount of carbon dioxide gas into the atmosphere after combustion.

Since the Industrial Revolution, the amount of heat-absorbing greenhouse gases such as carbon dioxide emitted into the atmosphere by humans has increased year by year, and the greenhouse effect of the atmosphere has also increased, causing a series of serious problems such as global warming.

Harm of the greenhouse effect: The greenhouse effect caused by environmental pollution refers to the heating of the earth's surface, which will bring serious consequences: 1) an increase in pests and diseases on the earth; 2) sea level rise; 3) abnormal weather and an increase in ocean storms; 4) The land is arid and the area of desertification is increasing.

and many unknown disasters and adverse effects.

Scientist**: If the increase in the temperature of the Earth's surface continues at the current rate, by 2050 the global temperature will rise by 2.4 degrees Celsius, the icebergs of the Arctic and Antarctic regions will melt significantly, causing a significant rise in sea levels and the flooding of some island countries and coastal cities, including several well-known international cities: New York, Shanghai, Tokyo and Sydney.

As the Arctic ice melts due to rising global temperatures, a deadly prehistoric virus that has been frozen for more than 100,000 years may resurface, leading to a global epidemic panic and a serious threat to human life.

What can we do?

On the one hand, people need to use electricity as sparingly as possible (because they burn coal to generate electricity and drive fewer cars).

On the other hand, protect forests and oceans, do not cut down forests indiscriminately, and do not pollute the oceans to protect the survival of plankton. We can also protect green plants by planting trees, reducing the use of disposable chopsticks, saving paper (wood for papermaking, not trampling lawns, etc.) so that they absorb more carbon dioxide to help slow down the greenhouse effect.

We live in this world, our children and grandchildren have to live in this world, our children and grandchildren have to live in this world, and we have to leave them this world that belongs to them as well.

We propose: each of us starts from ourselves, from small things, from the side, now we smoke a cigarette less, take a car less, plant more trees, plant more grass may leave this beautiful world suitable for survival for our children and grandchildren. We and our children and grandchildren will always have this world, this environment!

No, well, I don't dare to write casually, I can't write the restaurant, the company's relationship database is good, and it's raining heavily.

Recently, the state has begun to carry out the "I participate, I act, and jointly build an ecological homeland." I think it's very good, because building an ecological home really requires everyone to take action.

Some people may say: "Building an ecological home together is a major policy of the country, what does it have to do with us ordinary people?" "In fact, whether it is ecological civilization or not directly affects everyone's life; Whether everyone's behavior is civilized or not directly affects the process of ecological civilization construction.

Three years ago, my family happily moved into the community. Just moved in, it is really pleasant, between the brand new buildings, there are a number of small green belts, planted with green grass, planted with flowers and trees. It is no exaggeration to say that the community is like a beautiful large garden, with green leaves and red flowers shining against each other, and the taste is elegant.

However, the good times were short-lived. One day, I came home from school and found that a magnolia tree in the flower garden downstairs was missing. I was amazed and thought it was an accident.

Later, one after another, I saw that the green space was shoveled, and the flowers and trees were planed, and they were replaced by scattered greens, radish, shallots, and garlic, which turned from one piece to several pieces, and soon spread throughout the community. Since then, the community has less fragrance of flowers, more fecal smell, no bees and butterflies, and more flies and mosquitoes. The neighborhood has become deplorable and uninhabitable.

I've accused me of this behavior, and most people chose to be silent, and some in turn accused me: "Hey, I said you're young, dogs take rats — nosy." It's not your place, what does it matter to you when people grow some vegetables?

There are many more things like this in production life. Indiscriminate logging, destruction of greenery, littering, spitting, have become commonplace, and a small number of chemical plants, in order to save money, secretly discharge sewage, pollute the environment, endanger lives and ......Friends, think about it, in recent years, there have been fewer huge disasters in our lovely motherland? The 2008 snowstorm in southern China, the 2008 Wenchuan disaster in Sichuan, the 2009 typhoon "Morakot", the 2010 Yushu**, and the 2010 Zhouqu flash flood and debris flow in Gansu ......How many precious lives have passed away forever in an instant, bringing endless pain to loved ones and immeasurable losses to the country.

Why? Why? Why are there so many natural disasters now!

People on the earth, don't say that building an ecological home together is a matter for the country, if we don't build an ecological home today, then tomorrow's earth will be destroyed.

Let each of us participate and take action to build an ecological home.

The earth is the common home of mankind. Water is life.

The source of soil is the foundation of survival, clean fresh water.

and arable soil, has become the 21st century man.

class of the most important strategic resources.

Needless to say, in the material culture of human life water.

At the same time, the global capital is constantly improving.

Source and environmental problems are also becoming more and more prominent. Nearly a dozen.

years, climate change, deforestation and vegetation.

Destruction, increased soil erosion, and expansion of desertification.

The environment on which human beings depend is threatened.

Flank. There are currently 65% of the world's land area affected.

to varying degrees of land degradation impacts, among them.

Soil erosion, desertification, and salinization are.

The main forms of occurrence. Severe soil erosion.

It directly leads to environmental degradation, regional poverty and social deterioration.

will lag behind and has become an impact on regional development.

An important factor.

In the 21st century, China's soil and water conservation is facing.

Tough challenges. There are nearly 2 million square kilometers in the country.

The area of soil erosion needs to be controlled, and the soil and water flow is needed.

The situation of serious loss and deterioration of the ecological environment has not yet been achieved.

To be fundamentally contained, the modernization of our country, the city.

urbanization, the development of the western region, and population growth.

It will put a lot of pressure on the ecological environment. One.

In some areas, soil erosion has led to land retreat.

or desertification, land resources are more scarce, people.

The contradiction between the land and the land is very prominent. Preventing and controlling soil erosion, protecting water and soil resources, and improving the ecological environment have been.

It has become a very important and urgent task.

Let us join hands to prevent soil erosion, protect soil and water resources, and improve the ecological environment.

Build a beautiful home that human beings rely on for survival.

Let's talk about this topic first, and then talk about environmental issues and measures, and look to the future.
