We know that paper is made from trees, so recycling paper helps to save trees. Saving trees helps to prevent air pollution, soil erosion and floods.

In Britain, 12.5 million tons of paper are used every year. An average person uses 38kg of paper each year. It takes 24 trees to make one ton of paper. 67 % of paper used in Britain is kept for recycling.

Paper recycling is so important and we should recycle our waste paper. To get the benefits of recycling, we must give our contribution to the work.

Paper recycling is also a great chore for children depending on their age. It is an important way for children to learn about responsibility for saving money and trees, and working together. Recycling chores help children to learn about going green and protecting natural resources. Children can also help with recycling at home, at school and in the community.

Light pollution

Most of us are familiar with air, water, and land pollution, but did you know that light can also be a pollutant? Not many people know about this kind of pollution. Light pollution is the inappropriate or excessive use of artificial light and it can have serious environmental consequences for humans, wildlife, and our climate. Light pollution is a side effect of industrial civilization. Its sources include building exterior and interior lighting, advertising, commercial properties, offices, factories, streetlights, and illuminates sporting venues.

The fact is that much outdoor lighting used at night is inefficient, overly bright and, in many cases, completely unnecessary. This light, and the electricity used to create it, is being wasted by spilling into the sky, rather than focusing on the actual objects and areas that people want illuminated. For three billion years, life on Earth in a rhythm of light and dark that was created solely by the illumination of the Sun, Moon, and Stars. Now, artificial lights overpower the darkness and our cities glow at night. It disrupts the natural day-night pattern and shifts the delicate balance of our environment. Light pollution has negative impacts. It increases energy consumption, disrupts the ecosystem and wildlife and harms human health. Fortunately, concern about light pollution is rising dramatically. A growing number of sciences, homeowners, environmental groups and civic leaders are taking actions to restore the natural night.

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.

According to the passage, which of the following sentences is NOT true?

A. Ozone layer can't stop ultra violet rays from reaching the earth anymore

B. The toxic air is caused by sulphur dioxide which is released from coal burning

C. When the amount of  C O 2 in the air increases, it prevents plants in the process of photosynthesis

D. There are other different types of pollution besides air pollution
