- Definition: Thermal pollution means a change in the water temperature.

- Causes:

+ Power station are one factor. They use water in the nearby lakes or rivers to cool their equipment, which heats up the water. Then they dump the hot water back into its source.

+ Thermal pollution may also happen due to the discharge of cold water from reservoirs into warm rivers.

- Effects: Most aquatic creatures need a certain temperature to survive. Warmer water has less oxygen in it, and this can harm fish populations. Besides, warmer water can cause harmful algal blooms. This can change the colour of the water like in the first picture and, more seriously, the algea poisons the fish. - Solution: In many places, they build cooling towers like in the second picture to cool down the water from power stations.

Nowadays, environmental pollution is a hot issue, causing huge waves in public. There are a lot of scientific studies on this issue. Do you know that the cause of pollution originates from the tasks seeming small in our daily lives such as littering, deforestation, or the direct discharge of smoke from vehicles, factory into the environment without treatment. However, if these actions are repeated many times, gradually, the amount of pollution is increasing and has the opposite impact on our lives. The manifestation of environmental pollution is an increase in the carbon footprint in the air, soil and water, which is a gas that does not sustain life. Environmental pollution is also a direct cause of global warming, leading to a series of phenomena, such as the greenhouse effect, ice caps melting, natural disasters such as droughts, floods, volcanic eruption and so on. The sea level is rising, more and more natural disasters occur, which threaten all species, make some of which be rare or extinct, break the ecological balance on the Earth. Human beings are not exception. We are breathing polluted air, eating unsafe food. In recent years, we have seen a dramatic increase in the number of people suffering from respiratory and digestive diseases.

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 plastic 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.

Soil pollution has now become much more of a boiling issue to all countries in the world. Due to the appearance of many fertilizers and peside, farmers have been overusing them to contaminate the soil. This poses a great health threat as peole cultivate food on the land. Additionally, industrialization does not only lead to air pollution but also contribute greatly to the severeness of soil contamination. As more and more firms dump their untreated sewage right into rivers and the sea, the aqua environment become extremely hazardous for marine animals to survive. Moreover, the fresh water for daily activities will also be negatively affected. In order to improve the situation, several methods have been implemented by governments. However, I believe the most effective way to reduce soil pollution is raising people's awareness of the issue.

Air pollution always has bad effects on our life. Harmful gases, dust, and smoke enter into the atmosphere and make it difficult for plants, animals and humans to survive. We also can see some examples of the result of air contamination which occurs around us as global warming, acid rain, and depletion of ozone layer. The effects of air pollution are alarming, so governments over the world should have suitable policies of protecting the environment, especially air quality to create a clean world for our generation in the future.

Ngày nay, ô nhiễm môi trường là một chủ đề nóng hổi, gây lên làn sóng trong dư luận. Đã có rất nhiều công trình nghiên cứu khoa học về vấn đề này. Bạn biết không, nguyên nhân của ô nhiễm bắt nguồn từ những công việc tưởng chừng như rất nhỏ trong cuộc sống hàng ngày của chúng ta như xả rác bừa bãi, phá rừng làm rẫy, hay tù khói của xe cộ, các xí nghiệp thải trực tiếp qua môi trường mà không được xử lí. Tuy nhiên nếu những hành động này được lặp đi lặp lại nhiều lần, dần dần, lượng ô nhiễm ngày càng nhiều và tác động ngược lại đến với cuộc sống của chúng ta. Biểu hiện của ô nhiễm môi trường chính là sự tăng lên vè nồng độ carbon trong không khí, đất và nước, đây là chất khí không duy trì sự sống. Ô nhiễm môi trường còn là nguyên nhân trực tiếp dẫn đến sự nóng lên toàn cầu, dẫn đến hàng loạt hiện tượng như hiệu ứng nhà kính, băng tan hai cực, các thảm họa tự nhiên như hạn hán, lũ lụt, phun trào núi lửa,... Mực nước biển ngày càng dâng cao, ngày càng nhiều các thảm họa tự nhiên xuất hiện đã đe dọa đến tất cả các loài sinh vật, khiến một số loài trở nên khan hiếm hay thậm chí là tiệt chủng, gây ra sự mất cân bằng sinh thái trên trái đất. Con người cũng không ngoại lệ. Chúng ta đang hít phải không khí ô nhiễm, ăn những thực phẩm chưa đảm bảo chất lượng. Những năm gần đây, chúng ta chứng kiến con số tăng lên đáng kể những người mắc phải các căn bệnh liên quan đến hệ hô hấp, tiêu hóa. Nói tóm lại, ô nhiễm môi trường đang là vấn đề đáng lo ngại. Đã đến lúc chúng ta phải bắt tay hành động khắc phục hiện trạng này, bảo vệ cuộc sống của chính chúng ta.

We know how dangerous air pollution and soil pollution do to people. And to reduce them we have such many good ways. Remember to treat your rubbish before throwing it into the trash can. Don't throw trash everywhere. Planting more trees will transfer CO2 into O2, we need O2 to live. Use fewer plastic bags, plastic bags are cheap but they will slowly kill your health. That are a few of the many ways that will reduce air pollution and soil pollution.
