The composition about environmental protection is about 400 words, which is urgent.

The earth is our home and our mother. We rely on it and explore it. How beautiful this blue planet is, but you know, there is only one earth!

Regrettably, many people turn a blind eye to this simple truth and continue to do whatever they want, regardless of the safety of the earth's homeland. Qu, an environmental scientist, once said: "Only change can save the fate of mankind, and only change can make our descendants survive." One of the "changes" is environmental protection. That's right, so now many people are holding slogans and shouting empty slogans in the street, but they don't see much action. Will the pollution get better? Don't!

You see, the rivers in our city are black and smelly; Long queues of cars emit a lot of exhaust gas; A piece of green land has become a "stone forest"; The crisp birdsong disappeared without a trace. In this way, China will continue to be short of water, the air will become more and more turbid, and 10% of bird species will disappear in this century. The above things, we humans are the culprit!

Everyone knows that trees can absorb carbon dioxide, release oxygen and purify the air, which is a necessary condition for our human survival. However, some people cut down trees for money, which leads to excessive soil erosion, serious damage to the earth's vegetation, and desertification of oases and cities, threatening our human survival. As for the disposable chopsticks we usually use, it consumes dozens of acres of forest every day. In the eyes of those people, trees seem to have no value except for furniture and building materials. Does anyone not understand what trees mean to us? Our living area is already very small. If we go on like this, we may even lose our only land. In addition, the Yellow River, our mother river, has become one of the most polluted rivers in China in recent years. We can't watch the Yellow River dry up from our hands, so many environmentalists have studied plans to control the pollution of the Yellow River and tried to improve its water quality. However, without our participation, the Yellow River, the cradle of our life, will run dry and die.

If we destroy the environment again without restraint, we will naturally be punished. Those catastrophic floods claimed countless lives, and due to the greenhouse effect, glaciers in Antarctica and the Arctic melted, resulting in rising water levels and seawater flooding coastal areas, which caused great economic losses. Isn't this the best proof?

My hometown Guangning relies on Zhuhai eco-tourism to develop its economy. Now the environment of some bamboo forests is so chaotic that people complain. Eco-tourism in Zhuhai is the foundation of our development in Guangning. If the roots are destroyed, how can we grow lush branches and leaves and produce beautiful flowers?

Let's be kind to human beings and nature! I wonder if you have read the article 100 things you can do to protect the environment. In fact, there are many things we can do. For example, plant a pot of flowers and a tree on Arbor Day; Protecting wild animals is the balance of ecology; Cherish water resources and don't dump garbage into the river; Being a little environmental guardian, using every green anniversary to publicize environmental awareness, so that green mountains are always there, green water is always flowing, and the soil is always fragrant ... these are all things we can do. Why don't we want to practice?

Now, the ecological environment of the earth is getting worse and worse, and the environmental alarm has sounded. Let's join the ranks of environmental protection, create a bright future in which man and nature live in harmony, and let man and nature live endlessly.
