The earth is our common home. It selflessly dedicates its precious resources to mankind. However, while human beings claim the earth's resources, they wantonly destroy the earth's ecological environment. Take the water that we can see every day! 50% to 60% of the weight in the human body is water. Without water, there is no life. The fresh water resources on the earth only account for 3% of the total water resources on the earth, and only 0. 5%。 Therefore, water is a precious resource for human beings and the source of life. However, water pollution is quite common and serious in the world.
Nanjing is a beautiful city. Our "Young Eagle Holiday Team" went to Crescent Lake Park to do environmental protection activities. We also promote environmental protection knowledge to tourists. Although our strength is small, we also hope that our beautiful city will do its part. Let's protect our beautiful city together.
There is a French fable: "There is a big lily in the pond, which grows twice as fast every day. If it is not restricted, it will cover the whole pond within 30 days and suffocate the creatures in the water. Humans won't realize this danger until they are 29 years old-because lilies have covered half the pond. However, how much time is there to save the pond?
Not only water resources are polluted, but also clean air, one of the three elements of human life and health, is doomed. Reducing pollution and purifying the air, "Give me back my blue sky and red sun" has become the common aspiration of people all over the world.
With the rapid development of modern science and technology, we humans have invented vehicles such as cars, planes and trains. Although this is a great pioneering work in our history, it has also brought us great harm. Carbon dioxide emitted by factories and cars is a colorless and odorless highly toxic gas, which is not only harmful to human health; It also brought huge losses to agricultural production. A small amount of carbon dioxide gas will affect the life function of plants. Once the rice is fumigated, the yield will drop by 85%. 9%。 From this perspective, we must protect and cherish the atmospheric resources.
The levee of a thousand miles was destroyed in the ant nest. Now the earth is sick, riddled with holes and ugly. Do we realize that the time to try our best to save the earth is short?
Our earth is so lovely and fragile. In order to save the earth on which human beings depend, and also to save ourselves, let's take action and protect the environment together!
High school composition is 800 words, the topic is to care for the environment.
We all have a common "mother"-the earth. She nurtures human beings and is the cradle of our lives. However, in recent years, our "mother" has been scarred, which is entirely because most people lack environmental awareness and destroy the environment at will, making Mother Earth cry. In life, people who destroy the environment can be seen anytime and anywhere: in the street, people spit everywhere, litter everywhere, let their pets defecate everywhere, pretend as if nothing had happened and have no guilt. People around you are also indifferent, as if nothing had happened; In the forest, people keep cutting down trees, making the lush forest become desolate flat land; Black smoke is constantly emitted from the big chimney of the factory, which has blackened the whole sky and caused great pollution to the urban environment ... Some human actions have turned clear rivers into garbage rivers, blue sky into gray sky, renewable resources into non-renewable resources ... If this continues, mankind will perish.
In this regard, the state has also taken some environmental protection measures, such as establishing nature reserves, strengthening the protection of natural forests and the construction of public welfare forests, formulating laws and regulations on environmental protection, marine environmental protection and water pollution prevention and control, and strengthening international cooperation, and so on, and has made great achievements.
Now, people have realized this, and students are taking active actions to contribute to the cause of environmental protection:
In the past year, the school has carried out many activities related to environmental protection, encouraged students to plant more trees, issued the initiative of "using less plastic bags and staying away from white pollution", and taught us some environmental protection knowledge and common sense of life through blackboard newspapers, handwritten newspapers and billboards. As an "environmental guardian", I made a slide show in World Environment Day that day with the theme of "Protecting the environment and living a low-carbon life", which strengthened the students' awareness of environmental protection. Students also set up an "environmental protection group" to publicize the concept of environmental protection to more people and remind the general public to start from themselves, care for the environment and beautify their homes.
Students, there is only one earth for human beings, and each of us should cherish and cherish it. Protecting the earth and saving the common home of mankind has become the unshirkable responsibility of every citizen. Let's start with me, start with small things, protect resources and care for the environment, and jointly create a better tomorrow!

When human beings were born, they wanted to live in harmony with nature and live happily together. With the gradual evolution of human beings, people's lives have gradually entered industrial life, and what harmonious ecology has long been forgotten. It is said to protect wild animals, but it seriously pollutes the environment ... what's the matter? But I have forgotten. Wake up! Humans! Bare mountain, start planting trees from now on; Game on the table is forbidden to eat from now on; The polluted environment will be protected from now on. ...
The rapid growth of population, environmental pollution and the overuse of biological resources by human beings have led to a great deal of destruction of the natural habitats of animals and plants on the earth, and the survival of a large number of species has been seriously threatened. Among the nearly 30,000 species of higher plants in China, at least 3,000 species are threatened or endangered. In order to let more species survive, human beings, wake up! Don't chop down trees indiscriminately. A temporary temptation blinded my eyes, but I didn't know that a bigger disaster was coming. Wake up and rebuild my green home. There is still a glimmer of hope. Don't give up this glimmer of hope, plant a green future, and start sowing now. If the destruction continues, humans and animals will never survive. Protecting forests means protecting our own ecological homeland.
Although people often say that animals are friends of human beings. But is this how humans treat their friends? Catch them, eat them, kill them, destroy their homes ... in fact, human beings are really cruel. Animals used to live under the same blue sky as people, but later people began to kill a lot of wild animals for some benefit. Many wild animals are extinct or on the verge of extinction. Animals are good friends of human beings in this ecological environment. Like humans, they are lovely creatures. How could humans have the heart to kill them? Human beings are just blinded by interests, people, cheer up! Don't kill your good friend for profit, take action to protect small animals!
In this huge ecological environment, human beings control everything here. Every move of people will affect things in this ecological environment. Now, the environment is deteriorating. This is the ecological environment of human beings and all living things. Let's take action to protect the environment and don't make this tragic situation worse. Remedy is the right way now, and work hard for the ecological environment!
Protect the environment, build an ecological civilization and enjoy a green future.
