Looking at the earth at the moment, I can't help asking: "What is the earth like at the moment? Where did the earth in the green coat go? " On the earth, there is too much reduction in green and too much reduction in forests; Yellow has been increasing, and the land has begun to desert on a large scale.
Let's take a look at this busy city. Garbage is everywhere, and the air is full of bacteria. There were no clear rivers in the past. I don't know how much rubbish is covered in the river at the moment. Some people even pour industrial wastewater into rivers. At the moment, the river is full of white garbage, and the original clear water has turned into sewage, emitting a stench. Passers-by have run away with their noses covered. Imagine how fish can survive in such water. How can anyone drink such sewage?
At present, factories only want to improve their efficiency and get more benefits from themselves. Several industrial wastewater is discharged into the river, and toxic gas is discharged from the chimney like ordinary smoke. It should be understood that if these toxic gases are not inhaled, they will pollute the air in a large area. If inhaled, they will seriously affect people's lung function and make people difficult to breathe. It can be said that both are harmful.
Forests, the lungs of the earth, have brought countless benefits to mankind: flood control, sandstorm prevention, air filtration and so on. But what about now? Forests are decreasing in a large area at the rate of 38 hectares per minute. Without forests, our earth seems to have no pillars, and the earth seems to be crumbling.
What can we do to deal with the earth? What should we do?
First of all, we should start from the root cause and do what we can: save water, strive for less water pollution, and refuse to eat wild animals ... If everyone in the country turns off the tap after each use of water, we can save 19 water tanks at the end of the day. If we use more soap and less detergent, there will be plenty of water to avoid pollution. I have seen such a slogan: use renewable resources-don't wait until the energy runs out! Indeed, 90% of the energy currently used by mankind is oil, natural gas and coal. The synthesis process of these fuels takes hundreds of millions of years and is a non-renewable resource. Solar energy, wind energy, tidal energy and geothermal energy are renewable and are called renewable energy. People call those energy sources that do not pollute the environment "clean energy". Using clean energy can avoid pollution. For example, this year's national advocacy of "supporting green lighting-energy-saving lamps for all" is a good example: "China Green Lighting Project" is one of the key points of energy conservation in China. According to the implementation plan of the project, energy-saving and high-efficiency lighting lamps will be promoted throughout the country during the Ninth Five-Year Plan period. By the year 2000, we will strive to save 22 billion kWh of lighting electricity, save the corresponding coal burning in power plants, and reduce the emissions of sulfur dioxide, nitrogen oxides, dust, ash and carbon dioxide.
Wait, we can do many such things. Let's work together for environmental protection!

Dear students. When you walk into the park and enjoy the green trees and red flowers, when you walk along the Jialing River and breathe the fresh and sweet air, when you and your friends go out for an outing with great interest, suddenly, a pungent smell comes to your nose. Don't you feel uncomfortable and spoil the scenery? The answer is yes, so let's be little environmental guards.
During the winter vacation, my mother and I went for a walk in the park. I saw an uncle spitting in the corner. I went up to the uncle and said, "Uncle, please don't spit everywhere." Uncle said shyly, "thank you, little friend." I will try my best to correct it. " "I'm glad,
On the first day of school, I reported to school and saw a parent throwing cigarette butts. I didn't hesitate to pick up cigarette butts and throw them into the trash can. Which parent is extremely embarrassed now. I am very happy,
Not long ago, when I came home from school, I saw a lot of cigarette butts, peels and candy paper on the stairs ... I came home, put down my schoolbag, picked up my broom and bucket, and ran to the top floor to start cleaning. In an hour, I finally finished sweeping the corridor on the tenth floor. Uncle and aunt came home from work and saw the stairs so clean. They gave their thumbs up and said, "Yang Yang, we want to learn from you." My heart is full of joy. Since then, the corridor has been much cleaner.
Students, caring for the environment is everyone's responsibility. Let's all be little environmental guards. Starting from me, starting from the immediate things, let our life become better!

The faucet in the bathroom is on, and the battery is dead. Can you reach out and turn it off? Can you throw the trash can? When you watch TV and people walk away, do you turn off the power of the TV? When eating, is the food clean? When you go shopping, can you not use disposable bags? Cherishing resources and protecting the earth is an eternal topic and an eternal responsibility of mankind.
Water resources, which can be continuously regenerated, have contributed to mankind for a long time. However, due to the random destruction of human beings, the available pure water is getting less and less. When I write this paragraph, I will think of the Yellow River cut off, Rob dried up, and some big rivers were polluted ... These facts tell us that the current environment has been seriously damaged and brought serious consequences to mankind. For example, 23% of cultivated land is polluted, and 50% of water bodies are reduced or seriously polluted. 25% of mammals have no water to drink ... People should wake up, cherish resources and protect the environment, which is everyone's responsibility.
Water is the source of life. In the long history, the reason why water can maintain its clear and pure nature is inseparable from the efforts of several generations. Thanks to the hard care of our ancestors, water resources will not be destroyed. But people today always think that water is inexhaustible. Do you know this is a very wrong idea? At present, many places in our country are seriously short of water, so we must save a drop of water. Water can be recycled, such as washing feet, flushing toilets, washing rice, watering flowers, growing vegetables and planting trees ... saving every drop of water is to contribute to future generations of mankind.
I think there are many reasons for wasting water resources. Some people may not have a strong awareness of saving water, so the faucets are irrelevant after using water, resulting in a large loss of water resources. So we must protect the water resources of the earth.
It is everyone's responsibility to cherish resources and protect the environment.
