Environmental pollution is one of the impacts of human activities on the Earth. Pollution occurs when pollutants contaminate the natural surroundings; which brings about changes that affect our normal lifestyles adversely. Pollution disturbs our ecosystem and the balance in the environment. Pollution occurs in different forms; air, water, soil, radioactive, noise, heat/ thermal and light Let us discuss the causes and effects of air pollution on mankind and the environment as a whole.
Air pollution is the most prominent and dangerous form of pollution. It occurs due to many reasons. Excessive burning of fuel which is a necessity of our daily lives for cooking, driving and other industrial activities; releases a huge amount of chemical substances in the air every day; these pollute the air. Smoke from chimneys, factories, vehicles or burning of wood basically occurs due to coal burning; this releases sulphur dioxide into the air making it toxic.
The effects of air pollution are evident too. The increase in the amount of CO2 in the atmosphere leads to smog which can restrict sunlight from reaching the earth. Thus, preventing plants in the process of photosynthesis. Gases like sulfur dioxide (SO2) and nitrogen oxide (NO) can cause acid rain.
The decrease in quality of air leads to several respiratory problems including asthma or lung cancer. Chest pain, congestion, throat inflammation, cardiovascular disease, respiratory disease are some of diseases that can be caused by air pollution.
The emission of greenhouse gases particularly CO2 is leading to global warming. Every other day new industries are being set up, new vehicles come on roads and trees are cut to make way for new homes. All of them, in direct or indirect way lead to increase in CO2 in the environment. The increase in CO2 leads to melting of polar ice caps which increases the sea level and pose danger for the people living near coastal areas.
Ozone layer is the thin shield high up in the sky that stops ultra violet rays from reaching the earth. As a result of human activities, chemicals, such as chlorofluorocarbons (CFCs), were released into the atmosphere which contributed to the depletion of ozone layer.

Tạm dịch: Họ đưa tin rằng sự ô nhiễm đất đã đe dọa nghiêm trọng đến kế sinh nhai của rất nhiều người dân địa phương.
= C. Sự ô nhiễm đất được người ta đưa tin rằng đã đe dọa nghiêm trọng đến kế sinh nhai của rất nhiều người dân địa phương.
Động từ “report” chia thì hiện tại đơn, vế sau “that” chia thì hiện tại hoàn thành => có sự chênh lệch về thì
=> Công thức câu bị động: be reported + to + have + V_ed/pp
Cấu trúc: “pose a threat to something”: đe dọa đến cái gì đó
Chọn C
Các phương án khác:
A. Kế sinh nhai của rất nhiều người dân địa phương đã được đưa tin rằng đe dọa nghiêm trọng đến sự ô nhiễm đất.
B. Người ta đưa tin rằng kế sinh nhai của rất nhiều người dân địa phương đã dẫn đến tình trạng ô nhiễm đất rất nghiêm trọng.
D. Người ta đã đưa tin rằng sự ô nhiễm đất đã thực sự khiến cuộc sống của nhiều người dân lâm vào nguy hiểm.
