- Air pollution : Smoke and dust discharge chemicals into the atmosphere. Examples of toxic gases as carbon monoxide, sulfur dioxide, cloroflorocacbon substances (CFCs) and nitrous oxide are of industrial waste and vehicle 
- Water pollution occurs when surface water flows through the domestic waste, industrial waste water, pollutants in the ground, and groundwater seepage. 
- Soil pollution occurs when soil contaminated with toxic chemicals (concentrations exceed normal limits) by the activities of man as active mining, industrial production and use of chemical fertilizers Study or too much pesticide, ... or leaks from underground storage tanks. Most common types of soil contaminants are hydrocarbons, heavy metals, MTBE, herbicides, pesticides, and chlorinated hydrocarbons . 
- Radioactive Pollution , Noise pollution , Light Pollution ... 
Affect : 
+ For human health : Air pollution can kill many living organisms including humans. Ozone pollution can cause respiratory disease, cardiovascular disease, inflammation of the throat, chest pain, breathlessness.

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.

Ô nhiễm môi trường đã và đang trở thành vấn đề gây tranh cãi và nó đã gây ra nhiều khó khăn áp lực lên cuộc sống của chúng ta. Tình trạng ô nhiễm môi trường trên trái đất đã chạm đến mức báo động vì vậy hiện tại những giải pháp cấp thiết từ chính phủ cũng như sự hợp tác của mỗi cá nhân là vô cùng quan trọng. Điều đầu tiên nói đến, những hoạt động công nghiệp được coi là nguyên nhân chính cho việc ô nhiễm không khí. Cùng với sự nóng lên toàn cầu, sự đốt cháy những nhiên liệu hoá thạch, các phương tiện xe cộ và các nhà máy đang làm ô nhiễm không khí bằng sự thải ra những khí độc hại. Điều thứ hai, sự phá rừng bừa bãi cho việc sử dụng đất, lạm dụng phân bón và sự thải ra những chất gây ô nhiễm như túi bóng hoặc những túi không thể phân hủy xuống đất đã ảnh hưởng nhiều đến hệ sinh thái và dẫn đến sự ô nhiễm đất. Điều này đã để lại những ảnh hưởng tiêu cực lâu dài lên hệ thực vật và sự phì nhiêu của đất. Những giải pháp cấp thiết để làm giảm tác hại của ô nhiễm môi trường và giữ gìn môi trường cần được đưa ra sớm nhất có thể. Chính phủ có thể quản lí quá trình xử lí các chất độc hại của các nhà máy lớn vì vậy họ có thể ngăn chặn những chất ô nhiễm ra ngoài môi trường. Hơn nữa, những quy định và luật lệ nghiêm khắc hơn đối với sự khai thác rừng có thể giúp bảo tồn môi trường tự nhiên. Các cá nhân cũng cần phải có trách nhiệm và nâng cao ý thức về việc bảo vệ môi trường. Kết lại, ô nhiễm môi trường đang nhanh chóng trở thành một mối nguy hiểm với toàn cầu, ảnh hưởng trực tiếp tới cuộc sống của chúng ta, và vì lợi ích của môi trường cũng như của công dân trên toàn thế giới, chúng ta cần chung tay bảo vệ ngôi nhà chung của chúng ta- trái đất.

The environment is like our home and we all have a role to play in protecting it. Environmental protection is important because a clean and healthy environment is necessary for human well-being. Protecting the environment is protecting our health. Planting trees is one of the best ways to protect the environment. Trees provide us with oxygen, clean the air, and offer a home to many animals. To help the environment, take part in tree-planting activities in your neighborhood or plant a tree in your backyard. Environmental protection is not just something for adults, it’s something we, as students, can be a part of too. Remember, the Earth is our home, and it’s up to us to protect it for generations to come.
