Water pollution is the contamination of bodies of water such as lakes, rivers, oceans, and groundwater. Water pollution can have many different cause.The main reason for water pollution is the daily activities of everyone.The next reason, disasters always happen contaminate the water. Besides, the operation of the plant also pollutes the water. because industrial waste water has not been treated, it pollutes the water. Water pollution brings a lot of bad effects to people. Firstly, it seriously affects human health. Secondly, it affects water sources and aquatic organisms because water is the habitat of fish, crabs, shrimp. The most important measure is to raise the sense of responsibility of the community.In addition, we must save water; treatment of waste before being discharged into the environment.

The air pollution is so dangerous for people in my area. There are two problems about causes and effects. About causes, firstly, many vehicles discharge dust and smoke into the environment. Besides, factories dump waste poison out. Finally, people littering anywhere, such as parks, beaches, schools and even on the way. About effects, firstly, people can suffer from many respiratory diseases. Second, people can't live long because of lack of oxygen. And last, it will destroy the ozone layer and make it easier for the Sun rays to penetrate the Earth. In short, I think we should protect the air's purity before it's too late.
Transportation planning is a fundamental element of a comprehensive strategy for minimizing road surface emissions. Include the following:
- Land use and transportation planning,
- Manage travel needs,
- Management of transportation systems and support regulations,
- Appropriate policies on resource mobilization, taxation, pricing, subsidies, legal and institutional factors, promotion and awareness raising.
The principal principles in transport planning are:
- The transport planning must be integrated with the comprehensive development planning to ensure sustainable development.
- All plans and projects must be prepared on the basis of opinions at various levels, including users of the transportation system and stakeholders. These plans and projects will benefit the poor or harm them. Projects that want to be feasible must come from politicians to the public.
Model of urban transport development
- Limiting the growth of motorcycles, personal cars (in Vietnam's current condition).
- Limiting the development of pedicabs, lambros
- Complete the bus network, this type of public vehicles should be prioritized development number one in the urban Vietnam.
- Rough rickshaw (bicycles) out of the motor vehicle
- The pedestrian walkway must be maintained.
- There is a program to restrict traffic flow.
- Camera mount
- Complete the traffic rules and regulations
- traffic safety education.
- Solutions for the development policy of public passenger transport in urban centers.
The solution to plant trees to reduce noise is very effective and economical. In addition to reducing noise, trees also have many effects in environmental protection such as climate change, dust extraction and toxic gas ... Green trees grow in bands with better noise protection than growing into a continuous band. The results show that noise reduction through the green strip is most effective in the first 10 to 15 meters of the strip. Therefore, the width of each strip of trees should not be less than 5 m.
Environmental pollution has become a controversial issue that puts severe pressure on our rhythm of life. The pollution on Earth has reached such an alarming level that immediate involvement from governments and individuals collaboration now are of great importance. First and foremost, industrial activities are considered to be the main cause for air pollution. Along with the global industrialization, the burning of fossil fuels, motor vehicles and factories are contaminating the air by their emission of harmful fumes. In the second place, pervasive deforestation for land use, overuse of fertilizers and the dumping pollutants such as plas or non- biodegradable packing in the ground has affected the ecosystem and led to soil pollution. This puts bad long- term effects on vegetation and soil fertility. Serious attempt to relieve the effects of pollution and preserve the environment need to be made as soon as possible. Governments can monitor the exhaust purification process of large factories so that they can prevent dangerous exhaust from the environment. Moreover, stricter regulations and laws against forests exploitation can help preserve pristine environment. Individuals should be responsible and raise awareness for the protection of environment. In conclusion, pollution has increasingly become a threat to the globe, directly affects our life and for the sake of environment and all citizens around the world, we should work hand in hand to protect our friendly house- the earth.
Noise pollution is a noise in the environment that exceeds certain thresholds that cause discomfort to humans or animals. In most countries, noise sources are mainly from outdoor noise such as traffic, transportation, motor vehicles, aircraft and trains. school.
Unfavorable urban planning can generate noise pollution, as industrial and residential buildings can lead to noise pollution in residential areas. Records related to urban noise have been mentioned since ancient Rome
Outdoor noise can be caused by the operation of machinery, construction or musical performances, especially in some workplaces. Deafness can be caused outside (eg train) or inside (eg music).
High levels of noise can contribute to cardiovascular disease in people, such as coronary artery disease. In some animals, excessive noise can increase the risk of death by altering the carnivore, hindering the detection of prey, difficulty in reproduction, and possibly permanent hearing loss. telecommunications.
Noise can make resting almost impossible. This kind of noise is often called noise pollution. It is also called "community noise." It is noise that damages the balance of normal life for people and animals.
Most noise pollution is caused by transportation. Cars, trucks, trains, and airplanes can all be very loud. And in many cities around the world, people's homes are very close to these transportation systems. But even things like building tools and music can be noise pollution. Sometimes it can be difficult to find a quiet place.
Noise pollution is particularly a problem in developing countries. Growing cities and towns are not planned to reduce noise. Many homes and businesses are built next to busy roads. Traffic grows and with it the noise grows.
George Prochnik wrote a book about silence and noise in our world and culture. He said that noise can do more than just take our attention. Noise may harm our health. He says that noise can greatly affect our bodies. Most people know that loud noise can damage our ears. But noise can damage more than our ears. When a person experiences high levels of noise, his heart beats faster. His blood pressure gets higher. Noise can even change the balance of chemicals in a person's body.
Noise can also affect the way a person sleeps at night. A good night of sleep happens when a person is asleep for a long period of time. This is often called "deep sleep." But when there is too much noise at night, a person cannot get this deep sleep. Studies show that lack of sleep is connected to many different health problems. If a person is always tired, her body is not as strong. She is not able to fight sickness easily. She may also have a difficult time concentrating on work during the day.
Researchers in New York City studied the effects of noise on a school. The school was near noisy train tracks. Some of the rooms of the school faced the train tracks. Other rooms were far from the train. They were quieter. The researchers tested children over six years. The children on the noisy side of the school were not as good at reading as the children on the quiet side of the school. The school then built special walls near the tracks to make it quieter. After this, reading improved.
But noise does not just affect humans. Birds sing songs to communicate. But if it is too noisy, the birds cannot communicate. Cows feed less and produce less milk when it is noisy. Some studies even show that the growth of some plants can be affected by noise.
Louis Hagler is a doctor in California. He fights for quiet in cities. He believes that cities should treat noise like any other dangerous thing.
"We do not say to people 'you just have to learn to live with waste in your water.' Why should we have to live with waste in our ears?"
But for many people, the problem of noise is not about health. It is about peace. In many religions, quiet is connected to peace. People use times of quiet to communicate with God. They pray or read holy books. Noise can keep us from thinking about God. It may even be difficult to pray if too much noise surrounds us.
In some religions, holy men and women have special times of silence. Some of these people make a promise not to speak for a period of time. This can be very difficult. But these men and women see their silence as a way to control themselves and honor God.
These men and women use silence as a way to show respect. But this does not only happen in churches. All around the world people make their voices quiet to respect others. People are quiet in cemeteries, where people bury the dead. They are quiet in museums where people learn about art or history, and in libraries where people read books. People also use silence as a way to honor people who have died. Often, at special events orcelebrations, people will have a moment of silence. This is a short time when large groups of people quiet their voices to remember the dead. Quiet and silence is special. It is important.
But finding quiet places in a busy world can be difficult. Noise is all around, and sometimes you can not avoid it. But you can reduce noise in your life. The website Green Living Tips discusses the problem of noise on their blog. Here are some things they say to reduce noise in your life.
Keep your mobile telephone at a low volume.
If you have to raise your voice when you are talking to someone, something is wrong. Look for what is creating noise around you and what you can do to control it.
Train your pet dogs to not bark without reason.
Make an effort to reduce noise at night time when people are sleeping.
If you want to share your music with people who live near you, do not do it by playing music louder. Play music at a level that only you can hear, or only indoors.
If you live a life that creates a lot of noise, plant tall plants around your home. These plants will block some of the noise that you create.
Instead of driving a car or riding a motor bike, ride a bicycle instead. This will reduce noise on the roads. And finally, if you have children, take them to quiet areas and let them listen. Teach them to value quiet in their lives.
Escaping from the noise of life can give us energy. It can make a person calm. It can help bring balance to the body. Quiet can bring us closer to God and help us rest.

Soil pollution happens when human activities destroy the earth’s surface.
Causes: pesticides, herbicides, chemical industrial waste, deforestation...
Effects: soil pollution, soil erosions, the upper layer of soil is damaged, effects on wild-life...
Solutions: Fine heavily people who cut the forest and those who release chemicals waste into the ground.
Soil pollution occurs due to untreated disposal of industrial wastes into soil; it has high toxic contaminants, which leads to soil pollution. Industrial wastes have different amount of toxic contents and hazardous chemicals such that when deposited in soil, they affect the soil layer strength in the top soil, thus reducing the soil fertility and biological activity of the soil. In addition to that a hazardous effect leads to ecological imbalances, thus making troubles in crop production. Apart from that, it may cause severe health problem for those who are consuming such crops, because soil and crops are contaminated by toxic chemicals and hazardous materials.
