Environment means the surroundings in which we all live. It includes every form of living and non-living thing on the planet earth. The major issue these days we are facing is environmental pollution. The harmful pollutants in the environment contaminate the environment and have several harmful effects on biotic and abiotic factors. The major types of environmental pollution include air pollution, water pollution, noise pollution, soil pollution, etc.

Let us have a look at environmental pollution in detail below:

  • Air pollution: Air pollution is the emission of pollutants, chemicals and gasses in the atmosphere.
  • Noise pollution: Noise pollution off course includes the noise created by human activities, public and private transport such as aircrafts, etc.
  • Water pollution: Water pollution is caused due to the discharge of waste water from industrial, domestic and commercial waste in the surface water.
  • Soil pollution: Soil pollution is caused by the release of chemicals due to industrial, agricultural and other activities of living beings.

The environmental pollution directly affects the health of human beings as we breathe, eat, drink and live in this environment. Thus, human beings need to restrict the activities that cause pollution and damage our environment.

hello teacher, my nam i.... (giới thiệu bản thân) 

here, i will talk about my topic: talk about green activities and their benefits to the environment. The first is to plant trees. Trees help absorb Co2 and release gas 02, helping to cool the atmosphere. In addition, it provides shade, fruit and can store a large amount of watter. second, is waste recycling. It helps to treat wastes that pollute the environment, some plastics can even be processed for use. the third, choose green transport like carpooling, bus or bicycle. talking the bus helps reduce a part of emissions into the air, contributing to reducing the greenhouse effect. Cycling can both avoid tracffic jams in the city, improve your health,etc.... Thank you very much.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42.

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.
