A 600-word essay on the theme of my hometown and caring for the environment

Protect the environment

The environment is a precious wealth given to us by nature, and we should cherish it. Plants are nature's natural barriers; animals are human beings' friends; the ozone layer is the earth's protective umbrella; fresh water is our source of life. However, people always talk about environmental protection, but do not take protective actions. People should know: environmental protection is more important than reality!

A tree can absorb a large amount of carbon dioxide and other harmful gases every day, and release the same amount of oxygen, which can be breathed by people in a factory for a day. Flowers and plants can absorb noise. If you plant a flower lawn, you can greatly reduce noise pollution. This shows how important plants are to humans. But some people don't know this yet. Whenever I see the lawn being trampled by those people, and the placards about protecting flowers and plants being kicked down, my heart feels like a knife cutting it, and I feel extremely uncomfortable. If we lose the flowers, plants and trees, I can’t imagine what the world will look like! When I was in third grade, I studied the text "A Small Village". It was about a beautiful small village. Because people cut down trees excessively, the earth was exposed and floods washed away the village. What a terrible thing! Can this kind of thing be allowed to happen again in our city?

Animals are friends of mankind and the wealth of society. We should cherish them. I know from "Lingnan Youth Newspaper" and "Modern Primary School Student Newspaper": American cheetahs have disappeared from the world; mammoth elephants have long been killed in glaciers; saber-toothed tigers have long been extinct; European giant thunderbirds are close to extinction; whales are just hanging on. ; African elephants are driven to the edge of extinction. From now on, starting from me, eat less wild animals and stop predators from hunting animals. I remember that SARS spread in 2003 because people ate civet cats. SARS was caused by the mutation of the coronavirus.

I learned from the Internet that the ozone layer is called the protective umbrella of the earth, because it can block most of the ultraviolet rays. If there were no ozone layer, the earth would be scorched in an instant. Because of the extensive use of chemicals, a big hole has been exposed in the Antarctic sky.

Fresh water is also very precious. According to TV news reports: 70% of the world's water is salt water, which is not drinkable. According to statistics: out of three people, one will be short of water, not to mention that no salt water conversion machine has been invented yet. The sound of water flowing must mean that someone did not tighten the faucet. Saving water is just a talk. No one remembers that after those unconscious people wash their hands, they do not close the faucet and let the fresh water flow away in vain.

Dirty river water, exposed hillsides, poisoned fish, all along the coast, a full meter wide... Seeing those horrific scenes, I couldn't help but tremble with fear, as if I heard those creatures cries, and humans are the makers!

Tree is a friend of mankind. It dedicates oxygen and inhales carbon dioxide, purifies the air for mankind, and resists desertification, wind dust and red tide. But what do people repay it with? Indiscriminate deforestation. Do you know? China's forest area is only 1.58 billion hectares, and the forest coverage rate is only 16.5%.

Wetlands have been destroyed in China due to factors such as blind reclamation, plunder and development, increased pollution, overuse and other factors. One-third of the country's natural wetlands are in danger of being altered and lost. causing the ecological environment to lose balance. Factories discharge large amounts of waste gas, waste water, and waste, which deteriorates environmental quality.

Resources and environment-the guarantee of human life

p>

Since the birth of human beings, all food, clothing, production, and life have depended on the planet we live on, which consists of the atmosphere, forests, oceans, rivers, soil, grasslands, wild animals and plants, etc. The intricate and closely related natural ecosystem is the basic environment for human survival. For a long time, human beings have stuck in the process of civilization by conquering and plundering nature. It seems that they have never thought of protecting and nurturing the earth that nourishes human beings. In return, while achieving brilliant civilizational achievements, human beings' plunder of nature has left the planet we live on covered with scars. The growth of population and increase in production activities have also impacted and put pressure on the environment.

As we all know, human beings rely on the natural environment as the material basis for survival and continuation. However, with the development of modern industry, the natural environment has suffered increasingly serious damage.

Air pollution, water pollution, land pollution. . . . . . So much so that there is no more pure land in the world.

Perhaps you may think that the most important thing is to develop science and technology. After science and technology is developed, it is not too late to go environmentally friendly. Then you will regret it then. If we are now too intoxicated with our victory over nature and think we have achieved something remarkable, then we are not far from destruction

Climate warming, ozone hole, acid rain, toxic waste, The extinction of wildlife, as well as air and water pollution, are a series of global environmental problems we are currently facing. What should we do in the face of these problems?

Everyone has a responsibility to protect the environment, but we are still just students and cannot make a particularly big contribution to the environment of all mankind, but we can start from the environment around us, starting from protecting the school environment To start with, for example: comply with the regulations prohibiting littering of all kinds of waste, throw waste into designated locations or containers, avoid using disposable drink cups, lunch boxes, plastic bags, and replace them with paper boxes, etc. This can Greatly reduce garbage, reduce the pressure of garbage disposal, take care of flowers, plants and trees, give fewer New Year cards, keep the campus clean, etc.

Although these are small things, as long as we all take action, work together, start by saving resources and reducing pollution, and adjust our lifestyles, we can make a contribution to protecting the earth.

Save resources, protect the environment, and be a little master of the earth
