Môi trường hiện nay đang bị ô nhiễm nặng nề bởi chất thải của các khu công nghiệp, rác thải sinh hoạt, khói bụi các phương tiện giao thông... Với nhịp độ gia tăng dân số và tốc độ phát triển công nghiệp và hoạt động đô thị hoá như hiện nay thì diện tích đất canh tác ngày càng bị thu hẹp, chất lượng đất ngày càng bị suy thoái. Đối với nguồn nước bị ô nhiễm làm giảm độ đa dạng sinh vật trong nước. Ô nhiễm nước có nguyên nhân từ các loại nước,chất thải công nghiệp được thải ra lưu vực các con sông mà chưa qua xử lí đúng mức; các loại phân bón hoá học và thuốc trừ sâu ngấm vào nguồn nước ngầm và nước ao hồ; nước thải sinh hoạt được thải ra từ các khu dân cư ven sông gây ô nhiễm trầm trọng,ảnh hưởng đến sức khỏe của người dân,sinh vật trong khu vực. Ô nhiễm môi trường không khí là do khí thải của các nhà máy, khí thải từ phương tiện giao thông làm cho không khí không sạch hoặc gây mùi khó chịu, giảm thị lực khi nhìn xa do bụi. Như vậy, môi trường bị ô nhiễm là đe dọa đến cuộc sống con người. Chúng ta cần đánh lên hồi chuông cảnh báo để thức tỉnh mọi người, cần chung tay bảo vệ môi trường.

Nowadays, pollution is a popular term with everyone in the world and air pollution is one type of pollution. The definition of air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. There are some main reasons which cause air contamination such as burning of fossil fuels, agricultural activities, exhaust from factories and industries, mining operations, and indoor air pollution. 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.

We are living in the modern world and we have to face serious problems about the environment. One of the prominent problems is air pollution. Air pollution is caused by two specific reasons, which can be tackled by using appropriate measures. The first reason to be mentioned is human activities. People always litter everywhere and burn the rubbish without thinking of its consequences. Exhaust fumes from factories and vehicles are too much, so the level of air pollution is higher. Another reason is natural disasters. Drought often happens, which caused forest fires. This makes the air become more contaminated. There are several measures can be taken to deal with air pollution. The government should raise people's awareness. When people know the negative effects that air pollution creates, they will protect the environment more. We should plant more trees to protect our forests. To sum up, human activities and natural disasters are the main causes of air pollution. We have to take measures to protect the environment properly.
