Write a composition of about 800 words with the theme of giving love and caring for the environment.

The earth is our home and our mother. We rely on it and explore it. How beautiful this blue planet is, but you know, there is only one earth!

Regrettably, many people turn a blind eye to this simple truth and continue to do whatever they want, regardless of the safety of the earth's homeland. Environmentalist Qu once said: "Only.

Only change can save the fate of mankind, and only change can make our descendants survive. The "change" refers to environmental protection. That's right, so there are many people now.

Shouting slogans in the street, but not seeing much action. Will the pollution get better? Don't!

You see, the rivers in our city are black and smelly; Long queues of cars emit a lot of exhaust gas; A piece of green land has become a "stone forest"; The crisp birdsong disappeared without a trace. if

In this way, China will continue to be short of water, the air will become more and more turbid, and 10% of bird species will disappear in this century. The above things, we humans are the culprit!

Everyone knows that trees can absorb carbon dioxide, release oxygen and purify the air, which is a necessary condition for our human survival. However, some people cut down trees for money, which leads to excessive use.

Soil erosion has seriously damaged the vegetation of the earth, and oases and cities are also desertification, which has threatened our human survival. As for the disposable chopsticks we usually use, we need dozens of acres every day.

Forests, in the eyes of those people, trees seem to have no value except for furniture and building materials. Does anyone not understand what trees mean to us? Our living area is already very small.

If this situation continues, we may even lose our only land. In addition, the Yellow River, our mother river, has become one of the most polluted rivers in China in recent years, and its riverbed and sediment concentration are increasing.

. We can't watch the Yellow River dry up from our hands, so many environmentalists have studied plans to control the pollution of the Yellow River and tried to improve its water quality. But without our colleagues,

And the Yellow River, the cradle of our life, will run dry and die.

If we destroy the environment again without restraint, we will naturally be punished. Those catastrophic floods claimed countless lives, and the glaciers in the Antarctic and Arctic melted due to the greenhouse effect.

As a result, the water level rose, and the coastal areas were submerged by seawater, resulting in heavy economic losses. Isn't this the best proof?

My hometown Guangning relies on Zhuhai eco-tourism to develop its economy. Now the environment of some bamboo forests is so chaotic that people complain. Eco-tourism in Zhuhai is the foundation of our development in Guangning. If the root is broken,

If it is broken, how can it grow lush branches and leaves and produce beautiful flowers?

Let's be kind to human beings and nature! I wonder if you have read the article 100 things you can do to protect the environment. In fact, there are many things we can do. For example, plant a pot of flowers on Arbor Day.

Plant a tree; Protecting wild animals is the balance of ecology; Cherish water resources and don't dump garbage into the river; As a small environmental guardian, I use every green anniversary to publicize environmental awareness and keep the green hills always there.

Green water always flows and the soil always smells ... these are all things we can do, so why don't we want to practice?

Now, the ecological environment of the earth is getting worse and worse, and the environmental alarm has sounded. Let's join the ranks of environmental protection, create a bright future in which man and nature live in harmony, and let human beings

Keep breeding with nature.

Chapter II: Protecting the environment is everyone's responsibility.

Looking around, only uneven land, large areas of forests have been cut down and become wood products in people's lives. People are just selfish, so that groups of animals are displaced and rush to other places.

. This is not a false fantasy, this is a bloody fact.

Once upon a time, a large number of animals and plants in the world were extinct, and many animals and plants were on the verge of extinction. Why? This is all because of human deforestation and destruction of the ecological environment.

Is the root cause.

Land resource is one of the three major geological resources (mineral resources, water resources and land resources), and it is the most basic resource and labor object of human production activities. The degree of land use by human beings reflects human beings.

The development of civilization has also caused direct damage to land resources, mainly manifested in soil erosion, land desertification, secondary salinization of land and soil pollution caused by unreasonable farming, among which

Soil erosion is particularly serious, which is another serious crisis facing the world today. It is estimated that the global surface soil loss of cultivated land is about 23 billion tons/year.

Some people think that acid rain is a silent crisis, the most serious environmental threat that has ever attacked us, and an invisible enemy. This is not an alarmist. With industrialization and energy

With the increase of consumption, the discharge of acid is also increasing. They enter the air and form acid rain after a series of actions.

Although red tide has existed since ancient times, with the rapid development of industrial and agricultural production, water pollution is becoming more and more serious. Since 1933 was first reported in China, 1994 * * has a big rule of 194.

There were only four red tides before 1960s, and only 157 after 1990. Oil pollution is very harmful to water quality and aquatic organisms. Oil floating on the water surface can quickly spread to form oil.

The membrane blocks the contact between the water surface and the air and reduces the dissolved oxygen in the water. Oil contains polycyclic aromatic hydrocarbons carcinogens, which can be enriched by aquatic organisms and endanger human health. Sulfur dioxide mainly exists in coal and fuel oil.

Sulfur-containing substances are produced by combustion, followed by those from nature, such as volcanic eruptions and forest fires. Sulfur dioxide has a strong stimulating effect on human conjunctiva and upper respiratory mucosa, which can damage ventilator pipes and cause bronchitis.

Bronchitis, pneumonia, even pulmonary edema and respiratory paralysis. The elderly or chronic patients exposed to air with sulfur dioxide concentration of 0.5 mg/m3 for a short time, the mortality rate increased, and the concentration was higher than 0.25 mg/m3.

It will worsen the condition of patients with respiratory diseases. People who have been exposed to air with a concentration of 0. 1 mg/m3 for a long time have more respiratory diseases. In addition, sulfur dioxide is harmful to metal materials, construction, cotton spinning and chemical fiber weaving.

Commodities, leather paper and other products are easy to cause corrosion, peeling, fading and damage. It can also make plant leaves yellow or even die.

Protecting the environment is everyone's responsibility.

Chapter III: Protecting the environment means protecting the future.

The earth is our home, just like our mother, which provides us with resources and conditions for survival. We are the masters of the earth, and we should protect the earth as we protect ourselves.

Who doesn't want to make their home better and more beautiful? However, with the development of science and technology, there are more and more kinds of domestic garbage, most of which will cause environmental pollution.

Dyed. For example, our commonly used batteries will cause great environmental pollution if they are not handled properly after use. According to research, a section of waste button cell can make 600,000 liters of water undrinkable.

. If everyone throws away a waste battery, then water will become a luxury at that time.

So, in order to protect the environment, please classify the garbage.

On June 2008 1, China implemented the "plastic restriction order", saving 37 million barrels of oil every year. Plastic bags, this kind of thing is very common for ordinary families, but

But you know, plastic bags are a major factor of environmental pollution. Plastic bags are made of petroleum, which not only consumes a lot of resources, but also takes 500 years to decompose naturally.

Therefore, to protect the environment, please reduce the use of plastic bags.

The recent global climate change conference in Copenhagen once again sounded the alarm. Although we failed to achieve the expected results in the end, if we fail to do so, no matter how big the meeting is, it will only

This is only nominal. It was said at the meeting that the global average temperature is rising gradually and most icebergs have begun to melt. If this goes on, the world will be submerged. At present, the global average temperature is relatively low.

It is increased by 1. 1℃ than before. Although it is only a small 1. 1℃, it is the "global average temperature"! If the global average temperature rises by 4℃, the temperature in the Arctic and Antarctic will rise by 16℃, and then.

Trees can also be seen in the North Pole and South Pole. Think about it, what will the world be like at that time?

In fact, the chief culprit of these disasters is us humans. According to research, electrical appliances or other things we use every day will emit a lot of carbon dioxide, but carbon dioxide is one of the things that raise the temperature.

Big factor. If you reduce the use of electrical appliances, carbon dioxide emissions will also decrease. Automobile exhaust also contains a lot of carbon dioxide, so parents should be reminded to go to work or travel at any time.

Taking the subway or bus and driving as few private cars as possible can reduce a lot of carbon dioxide emissions.

Therefore, in order to protect the environment, please reduce the use of electrical appliances and drive less private cars to work or travel.

As the masters of society, it is our bounden duty and obligation to improve the global environment. If everyone in the world is environmentally friendly every day, we can create a brand-new beautiful world!
