The composition of protecting the earth is 600 words

The earth is the only home for all of us, flowers and trees. If the earth is on the verge of extinction, then the victims are ourselves. In order to protect the earth from environmental threats, how should we protect our earth? In order to protect the earth, we should first protect the forest. We should ban wood products. Take wooden furniture for example! If a family cuts down a tree every day, then within a month, hundreds of millions of families around the world will cut down enough trees to destroy a dense forest. Some people illegally cut down trees for convenience, resulting in serious forest damage, soil erosion, drought, flying dust and turbid air. If this continues, our green home will become a desert. In addition, we humans should quickly invent a packaging that can replace plastic bags. Now, mom and dad take everything home in plastic bags, no matter what they buy, such as food, medicine and daily necessities. These plastic bags are thrown into the garbage. When the wind blows, they will fly all over the sky. When the wind stops, plastic bags are everywhere. In summer, stinky flies whirl around. No matter who passes by the garbage dump, they will cover their noses tightly, because the smell is so bad. This kind of air is easy to infect diseases and endanger people's health. If this goes on, won't our earth become a garbage country? Protecting the environment as a primary school student, we should first take care of every grass and tree on campus, which is the home for our primary school students to grow up healthily; Our campus is very beautiful: graceful willows, patchwork flower beds in front of the classroom in the center of the campus, tall and straight green landscape trees, green grass, classmates, do you have the heart to climb branches and break willows at will, jump into the garden and paint the snow-white walls? We study hard in a civilized and polite way to make our beautiful campus more beautiful, our healthy bodies healthier and our green earth more charming.

When humans left the earth for the first time and looked at their hometown in space, people were surprised to find that among the known cosmic stars, only our hometown, the earth, was a blue planet.

Life means blue, and blue means life; The atmosphere and water that enable all life on the earth to survive also make our earth a blue star, a star full of life. However, in front of human beings, nature sometimes becomes bizarre and more and more difficult to control.

From the snowstorm in California to the flood in Bengal Plain, from the high-temperature heat flow sweeping the Mediterranean coast to the large-scale drought that has not been alleviated for many years in the African Plateau, the earth seems to be shaking like malaria, and human helplessness seems to have returned to 10,000 years ago.

If human beings are threatened by nature, it is somewhat a sigh of "helpless flowers falling"; Isn't it a great sin for human beings to "threaten"? Lop Nur, once one of the largest waters in Central Asia, was a big lake in the 1970s, but by the 1980s, the water in the lake had been replaced by terrible dead birds everywhere. No wonder Peng can't find water! For another example, Baiyangdian Lake, known as the "Pearl of North China", dried up again in the spring and summer of 1984, and the sparkling water surface disappeared from then on, and the bottom of Baiyangdian Lake was covered with yellow sand. How can this man-made consequence not be deplorable? In the pursuit and exploration of nature, human beings, as "conquerors", have taken ruthless revenge before celebrating victory.

A newspaper said that the desert in China is about 6.5438+0.6 million square kilometers, which is man-made. At present, it is expanding at an average annual rate of 654.38+0.560 square kilometers. If we can't control it, there will be 70,000 square kilometers of land in 2000, which is equivalent to Ningxia, and it will become a barren land! Why is this phenomenon not worrying and worrying? At the beginning of June last year, CCTV news broadcast reported a news that groundwater in Beijing, Tianjin and Tangshan had been exhausted due to predatory exploitation of groundwater. Among them, the Liaohe Plain has been mined by nearly one third, the Yellow River Plain by nearly half and the Haihe Plain by nine tenths. As a result, land subsidence, water quality deterioration, salty water surface rising and groundwater depletion have awakened many people in the dark. Please think about it. What do we want to leave for future generations?

China people believe in a "bright future" too much, and even if they are at the end of their tether, they will not feel terrible. Only when the next crisis comes, people are not allowed to be blindly optimistic: air, atmosphere and river pollution, lack of oxygen, ozone layer destruction and heat island effect. A few years ago, an environmental monitoring team of the United Nations brought a set of instruments to China for investigation. After getting off the plane at Beijing airport, it turned on the instrument and found that the pointer had reached the end of the highest pollution number, which exceeded the maximum measurement capacity, and the instrument failed! It is no wonder that the Beijing Olympic bid committee regards the control of air pollution in the capital as the top priority.

In this world, there may be nothing more important than air, but many towns in China, especially industrial concentration areas, have been filled with smog for a long time. It is really "black dragon dancing in the sky, black rain over the head", forcing people to send out their inner cries: "Give me back my blue sky, give me back my red sun!"

Coincidentally. The world-famous Yangtze River is a symbol of the splendid culture of the Chinese nation. A TV series "The Story of the Yangtze River", with its heroic momentum, depicts the magnificent scenery of the Yangtze River and evokes many beautiful memories in people's hearts ... But today's Yangtze River is worrying. Sewage from a paper mill in a city near the Yangtze River pours out like a waterfall, and black sewage bubbles are all over the river. Passengers passing by covered their noses and eyebrows. Many ports and rivers in the Yangtze River are covered with dust and cinders. If Li Bai and Du Fu visit the Yangtze River again, they will be puzzled. Where does the poetic prosperity come from? Or Bai Juyi's poem should be written as: "A setting sun is sprinkled in the water, half river is black and half mud."

"There is only one earth" is a resounding slogan put forward by 1972 at the human environment conference held in Stockholm. At last year's World Conference on Environment and Development, heads of state once again called on people to pay attention to "there is only one earth". Friends, when you hear this, you should suddenly realize that "it is everyone's responsibility to protect the environment"! Don't let a lot of forests be cut down, vegetation be destroyed and soil erosion. The earth, a beautiful home, who doesn't want the blue sea breeze to turn into rain, re-moisten the dry lakes and cracked land, and who doesn't want the fresh air blowing head-on, with green mountains and green waters, blue sea and blue sky, to show vitality to mankind forever.

Since ancient times, from the flood control in Yu Xia to the preparation of the Three Gorges Project today, from the goddess mending the sky to the construction of the Great Green Wall, all these have reflected the general desire of the people of China to protect and transform nature. Friends, we should also actively join the ranks of "environmental protection" and take active actions to make the blue sky always blue, the natural forests always lush, and the rippling rivers always clear ... Work hard!

Friends, let us always remember that there is only one earth for human beings!

Not long ago, I saw on TV news that a giraffe in Shanghai Zoo got sick and finally died. After dissection, it was found that there were many colorful foam plastic bags in the giraffe's stomach! It turns out that these plastic bags are the chief culprit that caused its stomach to fester and die, and my heart is shaking. What a poor giraffe!

Where did so many plastic bags come from? From the endless stream of tourists every day! We human beings call for the protection of wild rare animals every day, but we kill them unconsciously. How contradictory this is! However, this is the reality.

In fact, this contradiction exists in a large number in life. On the one hand, we all complain that the environment is polluted, but we have not polluted the environment ourselves! For example, on the one hand, we clamor that smoking is harmful to health, on the other hand, we are producing and selling cigarettes in large quantities. On the one hand, we strongly advocate not littering. On the other hand, when we eat popsicles, we often throw the wrapping paper on the ground casually. For example, some factory owners decorate their factories beautifully and luxuriously, but they secretly discharge sewage and wastewater into the river ... So, although we promote environmental awareness every day, the phenomenon of polluting the environment and endangering organisms is still repeated.

Why are there so many contradictions? In my opinion, the key is that many people don't pay attention to environmental protection. Blame others for polluting the environment, and forget that you are polluting the environment! Therefore, when promoting environmental protection, we should also add "start with me!" The second half of this sentence. Let the awareness of environmental protection really take root in each of us, and let us always consider protecting the environment when doing anything.

I hope that the poor giraffe will never die innocently again, and that its death will awaken the conscience of many of us!
