    7.1. Talking about physical elements of environment

    7.1.1. Learning activity: Reading and Text Analysis

    Read the text below and answer questions that follow:

    • Text: The physical environment

    The physical environment can be defined as that which operates on an 

    ongoing basis regardless of the persons in it. This physical environment 

    then affects the actions of and outcomes concerning the people within it. 

    The physical environment includes land, air, water, plants and animals, 

    buildings and other infrastructure, and all of the natural resources 

    that provide our basic needs and opportunities for social and economic 

    development. 

    Say, for example, you are playing sport and it is a windy day. You have 

    to adjust your game to ensure that you allow for the way the wind is 

    blowing. All processes and behaviours take place within specific physical 

    environments. Within a classroom for example lighting, acoustics, size, 

    comfort, safety, access to technology, etc. create and add to a physical 

    environment that is either conducive to learning or perhaps distracting.

    Therefore, a simple definition of any physical environment would be 

    your natural surroundings including whether it is clean or dirty and the 

    things within it and how they interact to create a ‹space.›

    It is also known as the whole physical and biological system surrounding 

    man and other organisms along with various factors influencing them. 

    The factors are soil, air, water, light, temperature etc. These are called 

    A biotic factors. Besides a biotic factors, the environment is very much 

    influenced by biotic factors which include all forms of life like plants, 

    animals, microorganisms etc. Man is thus an inseparable part of the 

    environment. Man and Environment have very close relationship with 

    each other. The social life of man is affected by environment. This is the 

    reason for various types of social and cultural activities around the world. 

    The hilly people have different life styles than people in the plain area. 

    Similarly, people around the world differ in their food, cloth, festivals etc. 

    All these are influenced by the factors around him.

    Natural vegetation, such as forest cover, is usually the most benign 

    of land uses, with higher infiltration and reduced runoff rates. The 

    opposites of forest cover are urbanized areas, where large surface areas 

    are impermeable, and pipes and sewer networks augment the natural 

    channels. The impervious surfaces in urban areas reduce infiltration 

    and can reduce the recharge of groundwater. In addition, urban runoff 

    contributes to poor water quality.

    Agricultural activities are major forms of land use, including row 

    crops, rangelands, animal farms, aquaculture, and other agribusiness 

    activities. Cropping activities involve soil and water manipulation 

    through tillage and irrigation, thereby affecting runoff water and 

    groundwater resources. If improperly used, fertilizer and plant protection 

    chemicals in agricultural operations can affect water resources and 

    ecosystems.

    Urban and agricultural land uses contribute to what is termed nonpoint 

    source pollution in watersheds. Nonpoint-source pollution is defined 

    as diffuse (spread-out) sources of contamination from a wide area 

    of a landscape, often difficult to be attributed to a single location. 

    Transportation infrastructure (e.g., roads and airports) is another type of 

    land use that affects water resources through road runoff and alterations 

    to components of the hydrologic cycle.

    Therefore, a cleanliness and beauty of the environment is also important 

    for people’s sense of wellbeing. For many people, access to an attractive 

    physical environment contributes greatly to their contentedness with life. 

    A healthy environment also provides recreational opportunities, allowing 

    people to take part in activities they value. The clean, green environment 

    is also integral part of national identity, and guardianship of the land 

    and other aspects of the physical environment is seen as important part 

    of social wellbeing.

    7.2. Describing environmental features and their roles

    7.2.1. Learning activity: Reading and Text analysis

    Read the following text and answer questions given: 

    • A text: Environmental Features 

    Rwanda has a temperate tropical highland climate, with lower 

    temperatures than are typical for equatorial countries due to its 

    high elevation. Kigali, in the centre of the country, has a typical daily 

    temperature range between 12 °C (54 °F) and 27 °C (81 °F), with little 

    variation through the year. There are some temperature variations 

    across the country; the mountainous west and north are generally cooler 

    than the lower-lying east. 

    There are two rainy seasons in the year. The first runs from February to 

    June and the second from September to December. These are separated 

    by two dry seasons: the major one from June to September, during which 

    there is often no rain at all, and a shorter and less severe one from 

    December to February. Rainfall varies geographically, with the west 

    and northwest of the country receiving more precipitation annually 

    than the east and southeast.

    Mountains dominate central and western Rwanda. These mountains are 

    part of the Albertine Rift Mountains that flank the Albertine branch of 

    theEast African Rift. This branch runs from north to south along Rwanda’s 

    western border. The highest peaks are found in the Virunga volcano 

    chain in the northwest; this includes Mount Karisimbi, Rwanda’s highest 

    point, at 4,507 metres (14,787 ft). 

    Rwanda has many lakes, the largest being Lake Kivu. This lake occupies 

    the floor of the Albertine Rift along most of the length of Rwanda›s 

    western border, and with a maximum depth of 480 metres (1,575 ft), it 

    is one of the twenty deepest lakes in the world. Other sizeable lakes 

    include Burera, Ruhondo, Muhazi, Rweru, and Ihema, the last being the 

    largest of a string of lakes in the eastern plains of Akagera National 

    Park. Therefore, it is very important to care for our environment because 

    as some the features show without it there is no life as discussed in the 

    following paragraphs

    No trees, no forests! No forests, no rainfall! No rainfall, no water! No 

    water, no power! No power, no industry! No industry, no jobs! No jobs, no 

    money! No jobs, no money! No money, no food! No food, no life!

    Perceptibly, forests are very important as this sequence show. Destroying 

    forests has serious environmental, economic and social consequences. 

    Anyone in drought areas should remember that we have suffered 

    crippling droughts as well as water and power rationing in some parts 

    of Africa. Recovering from these disasters takes a long time.

    In counties which heavily depend on agricultural produce both for local 

    consumption and for export, rain is very important. Trees attract rain 

    and we should do everything possible to preserve them. We should even 

    plant more.

    Trees also prevent soil erosion and flooding. Soil erosion carries away the 

    productive soil while flooding leads to loss of life and property.

    In Kenya’s Western province, Busia district, Budalangi constituency

    and its surroundings, the inhabitants cannot build permanent homes 

    because they know in the month of April they have to move to high 

    grounds because of flooding that causes loss of property and even life.

    In addition, forests provide catchment areas for some largest rivers 

    and lakes. From these rivers and lakes, we get water for domestic use, 

    irrigation and we can also get sea food. On the rivers are dams from 

    which electricity is tapped or generated.

    For example, River Nile is a major hydro power generation that serves 

    Uganda, Kenya and Rwanda. Did you know that Lake Victoria has its 

    major tributaries in Kenya and these tributaries emanate from the Mau 

    forest?

    Due to human activities in the forest, the tributaries are reducing water. 

    As a result Lake Victoria on the Kenyan side is reducing in water flow 

    and if the situation is not checked, this will affect the people of Egypt who 

    rely entirely on irrigation from River Nile whose source is Lake Victoria.

    Moreover, forests play a significant role in our atmosphere. By absorbing 

    carbon dioxide from the air, they act as a filter thus leaving our air 

    fresh and clean. Forests are also the most important defence against 

    climatic changes such as global warming. If we destroy the forests the 

    chain is broken as well as our lives.

    B. Reading and exploitation of texts

    Read the text below and answer questions given.

    • Text 1: Protect your environment 

    Many people say there is a need to protect the environment, but do not 

    really make any effort to do anything about it. Are you one of these 

    people? What can we do to encourage people to take action to protect the 

    environment?

    Most people are increasingly aware of the need to protect our environment. 

    Despite this, not many of us are really taking steps to reduce our impact 

    on the planet. In this text, I will suggest some steps each of us can take 

    and some ways to motivate others to do the same.

    Many environmental problems seem so big that only governments, local 

    authorities or big companies can deal with them. One example is globa

    warming. We need government action to reduce emissions from coal 

    and oil burning power stations and to develop safer sources of power. 

    These require tough regulations and huge investment. The loss of forests 

    and other habitat is another problem. How can we as individuals stop 

    the destruction of the Amazon or Indonesian rain forests? Yet another 

    example is waste. When people live in cities, other ways may be recycling, 

    picking up trash, no polluting and decrease pollution overall, saving 

    animal habitats and so much more. 

    We should care for the environment because it’s our real home, we live in 

    it and we don’t want a nasty living of trash everywhere with stenches

    also animals can die from our trashes such in beaches, they can get stuck 

    in the can plastics. We need to recycle because recycling takes trash and 

    processes it in some way to make a useful product. Composting falls 

    into this category. Glass, plastics, paper, steel, and cardboard are other 

    materials that may be recycled. The added benefit of compost is that 

    it can be done in your own backyard. We still need to recycle all the 

    plastic that we use because it gets melted and reused again for more 

    supply for our needs.

    When we don’t recycle, we have less plastic reusing than before and cause 

    a lot more money and man labor time to recycle it for us in the landfills. 

    Also, most of it gets burned to dispose of it all because we have no room 

    for all the landfills and they cost too much to have. Really, we should all 

    try to reuse before recycling but either works just fine. So, when we 

    reuse our belongings like finding alternate uses for trash rather than 

    disposal. 

    Share unused portions with neighbours or charities. Donate books 

    to the library; give old clothing to charity, etc. Now we also need to 

    reduce which is includes reducing the amount of total waste by steps 

    such as buying only the amount you need, persuading manufacturers to 

    reduce the amount of packaging they use. It also includes steps such as 

    mowing your lawn with a mulching mower and leaving the clippings on 

    the grass. “Waste” is never generated. So, we don’t want to buy too much 

    of anything for ourselves everyone needs the same things such as water 

    bottles, plastic bags, and much more. And for mountainous places, it is 

    important that people can make terraces, planting also some trees which 

    may protect the soil. 

    In conclusion, our choices, however small, do have a real impact. If each 

    of us made took two or three simple steps to live more simply, imagine 

    the positive effect on the planet!

    2. Write two paragraphs describing different ways of protecting 

    environment. Read the guidelines on writing a paragraph in 

    unit five of this book

    7.3.3. Language structure: Use of expressions of purpose

    1. Read the following paragraphs and identify expressions of purpose used 

    The trees’ roots suck water deep from under the ground to as low as 200 

    feet. They hold the soil together so that erosion is prevented. They absorb 

    rain during rainy days in order to help plants grow well.

    Mary lives in Gakenke District which is a mountainous area. Last 

    year, she planted different trees so as to protect the soil. However, her 

    neighbours did not do the same and affected her soil later. The local 

    leaders sensitize every person to make terraces and some irrigation so 

    that they could not get affected by soil erosion again. 

    Last week, Land manager at sector level visited them and said that in 

    order to avoid soil erosion people should also get water from their houses 

    in addition to other methods used. 

    • Notes

    Expressions of purpose: to, in order to and so as to

    a. In order to

    We can use ‘in order to’ or ‘so as to’ instead of ‘to + infinitive’. This just 

    makes it a bit clearer that we are talking about goals or intentions and 

    it’s also a bit more formal. It doesn’t change the meaning.

    • I went to London in order to study Environmental education. 

    • I went to London so as to study Environmental education.

    Use to, so as to, and in order to express purpose in the affirmative 

    form

    Examples:

    • He is looking for a part time job to save some pocket money.

    • She wakes up early in order to be on time to work.

    • They visited him so as to offer their condolences for the death of his 

    wife.

    Use so as not to and in order not to express purpose in the negative form.

    Examples:

    • They woke up early in order not to be late.

    • She exercises regularly so as not to get fat.

    • He helped the new policewoman so as not to fail in her first mission.

    b. Purpose with so that

    You can also express purpose with so that. In this case you generally 

    need to use a modal

    Examples:

    • He turned down the music so thathe wouldn›t disturb the neighbours.

    • He got a visa so that he can travel to the USA.

    • He decided to stay in England for a while so that he could practice 

    his English language
