The earth is a big family where we humans, animals and plants live and multiply. But now, the earth is no longer that clean and beautiful earth. It is becoming riddled with holes and bruises, and it is crying alone. I don't know who to tell about the misfortune it faces. At present, the ecological environment is deteriorating, and the biggest influence on us is water resources. According to relevant data, the laying of drainage system and the extensive use of cleaning agents are increasing day by day, which consumes oxygen in water, kills fish and worsens the ecosystem. Human activities will also discharge a large number of industrial and agricultural pollutants into rivers and pollute water bodies. According to relevant data, more than 420 billion tons of sewage are discharged into rivers every year, polluting 5.5 trillion tons of fresh water. What do you think of when you see this shocking data? Yes, this is what happens when human beings destroy the environment, and this is the punishment that nature gives to human beings! When the sky above us is no longer clear and blue, do we remember to protect our living environment? When the land under our feet turns into yellow sand and desert, do we regret not cherishing our nature? In the face of everything that used to be beautiful, we can't help but ask loudly: "Who will protect our green home?" The wheel of history is rumbling towards the 22 nd century. As a primary school student and ordinary citizen, we must stand up bravely and appeal to everyone: it is urgent to protect the environment, and we are duty-bound! Who wants to see that Mother Earth, who has nurtured us diligently since ancient times, is about to become a black land where she wants to cry without tears? No, nobody wants to see it! Yes, many forests have been destroyed because of uncontrolled deforestation and neglect of ecological balance protection. Birds have no home, and they will never sing and laugh again; The earth is no longer full of vitality without beautiful green clothes. However, some people still don't realize that our home is slowly being destroyed! The earth is a harmonious and beautiful green, and the flowers are charming; Only when there is pure green in the heart can the soul become more brilliant. Humans need green, and Mother Earth needs green more. Let's join hands to create a green environment, make the blue sky bluer, the water clearer, and make our mother earth more lovely and full of vitality!
There is only one earth for human beings, which is the natural resource on which human beings depend. Caring for the earth means caring for your home. However, in recent years, the environment of the earth is getting worse and worse: global warming, frequent disastrous weather such as hurricanes and rainstorms, and frequent infectious diseases such as SARS and bird flu have brought serious threats and inconveniences to human life and work. These are the results of people constantly "hurting" the earth. Large areas of forests have been cut down, green hills have been dug up, beautiful grasslands have become deserts, and clear rivers have become turbid. With fewer trees, bare mountains, bare grasslands and dark water, people's living environment becomes worse, the air they breathe is worse, and the living environment is "occupied" by many harmful things. Viruses will take the opportunity to enter people's bodies, and we humans will suffer from some terrible diseases.
A few days ago, I saw a cartoon in the newspaper: a man was sitting on the treetop, cutting the branches where he was sitting. "Hum, that's funny." Some people may think so. Don't you think this is just a funny cartoon? Isn't that sarcasm? Don't you realize that it is warning us that human beings are unconsciously hurting themselves while destroying the environment?
When you are walking in the street, what will you do if you want to spit? If you choose to throw up on the ground, have you thought about it? Are you hurting yourself? A mouthful of phlegm contains a lot of germs, which will multiply and infect in sunny days. Similarly, when you cut down a tree,
