Most of the air pollution results from the burning of fossil fuels, motor vehicles, factories, aircraft and rockets. This can cause acid rain which damages water, soil, and vegetation. Air pollution also contributes to the greenhouse effect which can lead to a series of environmental problems such as global warming, polar ice melting, rise of sea levels and loss of land.

Water pollution is a result of dumping pollutants such as detergents, pesticides, oil, and other chemicals in rivers, which makes the water unclean or contaminated. Rubbish blockages in rivers can also cause pollution.

Soil pollution is a consequence of human activities that alter ecological factors that cross the ecological boundaries of the communities living in the soil. The land environment is home to human beings and most of the shallow creatures, the foundations for civil, industrial and cultural constructions. Land is a precious resource, people use land resources for agricultural production to ensure food supply for people. But with the pace of population growth and the pace of industrial development and urbanization, the area of ​​arable land is shrinking and land quality deteriorates, the average land area head drops. Parularly in Vietnam, the actual depletion of land resources is very worrying and serious.  What do we need to do to protect the environment? That is the question that every one of us needs to answer. In my opinion, protecting the environment is the responsibility of the whole community. Everyone must have a sense of protection. The green, clean, beautiful environment will make our lives better. From the house to the alley, from the alley to the school etc. The place is also clean and airy, many trees, air will be fresh, health will be guaranteed. That everyone wants. At present, I see my class, our school where the concentration of people, not very clean, garbage also lunged, trees are still less. On the street, there are public trash but few people put garbage in the bin, you do not throw it, making the street scene is not beautiful. To protect the environment, I feel we must always have a sense of environmental protection in parular: Do not throw garbage indiscriminately, do not discharge dirty water into ponds, do house cleaning, alleys, schools, not breaking flowers ... and propaganda for people always have common sense and responsibility for environmental protection.

Well, my community now is having a big problem that the streets and the lakes are full of rubbish. Many people see that but they don't care. Personally, I think that if we still let the streets and the lakes are full of rubbish, it will have a bad affect to our health. Therefore, I want to solve this problem by clean up the streets and lakes. On the whole, it's too wonderful if i do that, I think it's too difficult for me to do it alone, so I asked my friends help me to clean up the streets and lakes. And they undoubtedly they will help me. We clean the street and the lake, put all the rubbishes into the waste baskets. Afterall, eveything is great. I feel very happy because I can help our community to become a better place
