A tree can absorb a lot of carbon dioxide and other harmful gases every day, releasing the amount of oxygen equivalent to the amount that a factory worker breathes every day. Flowers and plants can absorb noise. If you plant a flower lawn, you can greatly reduce noise pollution. This shows the importance of plants to human beings. But some people don't know this yet. Whenever I see the lawn trampled by those people and the placard that loves flowers and plants that has been kicked down, my heart is like a knife cut, which is very uncomfortable. If I lose flowers and trees, I can't imagine what the world would be like! In the final analysis, human protection of the environment is based on the protection of the increasingly depleted resources on the earth and the minimum conditions for our survival and development. When industrial civilization entered the 20th century, the damage to the environment became more and more serious, and the utilization of resources became abusive, which aroused more and more vigilance. Governments of various countries have taken many measures to protect the environment, and great progress has been made in environmental protection, which has become the knowledge of human society. Up to now, when it comes to environmental protection, few people will openly oppose it, but there is still a lot of work to be done to really protect the environment and resources consciously and for a long time. I think we should first establish the awareness of environmental protection in the whole nation, specifically, we should establish the awareness of resources and survival. Let everyone realize that protecting the environment and resources is closely related to each of us. Protecting the environment is not only a great cause for future generations, but also directly related to the survival of human society today! You can't hold the idea that there is little difference between environmental protection and environmental protection, you can't relax, and you can't be afraid of trouble. Of course, government departments have an important responsibility for environmental protection, and every unit, every enterprise and everyone has a more direct and specific responsibility for this. As long as we start from ourselves and start from small things, we will work together and persevere, which will definitely leave a clear water and blue sky for the society and ourselves. At this point, middle school students in Beijing gave us many good suggestions. Is there anything we should hesitate about?
