The current environment is heavily polluted by industrial waste, domestic waste, traffic smoke ... With the population growth rate and the growth rate of industry and activities. With the current urbanization, the cultivated land area is narrowed down, and the quality of land is degraded. For polluted water, it reduces the diversity of aquatic organisms. Water pollution is caused by different types of water, industrial wastes are discharged into river basins but have not been properly treated; chemical fertilizers and pesticides that seep into groundwater and pond water; Domestic wastewater is discharged from riverside residential areas, causing serious pollution, affecting the health of people and creatures in the area. Air pollution is caused by factory emissions, exhaust gas from vehicles makes the air not clean or causes unpleasant odors, and reduces vision when looking far away due to dust. Thus, the polluted environment is a threat to human life. We need to sound alarm bells to wake up everyone, we need to join hands to protect the environment.

Currently, environmental pollution is a problem that alarms the whole society. Environmental pollution is an environment in which harmful substances and impurities appear in the environment, causing negative impacts on nature and human life. Environmental pollution occurs in both soil, water, and air environments. The reality of the phenomenon of environmental pollution is reported by the media every day with the overwhelming image of waste and alarming statistics on the environmental pollution. Just recently, the atmosphere of Hanoi city has exceeded the level of heavy pollution. With such serious environmental pollution, not only people's lives are threatened but the natural ecosystems on Earth are also affected, especially the consequences of the greenhouse effect and the melting ice phenomenon. due to global warming. The main cause of this situation is that people's awareness of environmental protection is too poor and that solutions to environmental protection and waste treatment have not been fully implemented. So, from now on, every person needs to be aware of the harmful effects of environmental pollution, we reclaim nature and minimize the amount of waste and emissions. By doing this, we can protect the Earth, protect life as well as human development and nature.
