Human population growth is becoming a huge issue in our world today. The population is increasing rapidly. The reason that it is becoming a concern is because it has affected the economic, environmental, and social aspects of our world. In the film Frontline: Heat, we can see how there might not be a future for our planet unless we are able to reduce the emissions and make our world a safe place. Not only for the present but also for future generations so that they are able to live long and healthy lives. An increase in human population can influence our economy. Some of the factors that are affected are unemployment, poverty and the restriction of economic expansion. When the population increases, the cost of health, education,…show more content…

The revenues are not enough to provide for the population growth. This affects families to save less because they are spending all of their income on basic needs and cannot afford to educate their children, which produces poverty in the next generation. This results in low qualification and low chance of employment for children when they reach the working age. Due to this, industries and services cannot develop. With the increase of population, the volume of employment and unemployment increases. The number of unemployed depends on the size of the active population called the Labour Force. If the growth rate of the population is higher than the job opportunities available to the labour force, unemployment will occur. When there is an increase in population, society is solely focused on providing the basic needs. This results in the lack of obtaining education and because of this they cannot help the economy expand. Also, there are more consumers with the increase of population than producers, causing the restriction of economic expansion.
Not only is our economy impacting the population, but so is the environment. “Population is the number one threat to our environment”. (Population Growth
Impacts on the Environment website). Our population is rising beyond the earth's ability to maintain a reasonable quality of life. This enlarged population has also increased the land uses, resource uses and pollution problems. A raise in land use

Population projections represent the playing out into the future of a set of as-sumptions about future fertility and mortality rates. More public education is needed to develop more awareness about population issues. Facts like the size or the growth rate of the human population should be in the head of every citizen. Schools should inform students about population issues in order for them to make projections about the future generations.

Action plans and strategies can be developed to increase public understanding of how rapid population growth limits chances for meeting basic needs. The spirit of open communication, and empowerment of individual women and men will be key to a successful solution to many population problems. Collective vision about health care, family planning and women's education at the community level build a basis for action. The creation of action plans help to meet challenges to find coop-erative solutions. Free and equal access to health care, family planning and educa-tion are desirable in their own right and will also help reduce unwanted fertility.

Individual choice, human rights and collective responsibility are key to al-lowing families to plan the size and spacing of their children. It is essential to achieve a balance between population and the available resources. Teachers, par-ents, community workers and other stakeholders should extend the range of choices about available resources to individuals, especially women, and by equal-izing opportunities between the genders from birth onwards.

Teachers, parents, other educators, politicians and other concerned citizens can practice how to make good decisions in everyday life. Decisions about family size, and resource will affect the future generations. Through commu-nity forums, specific issues about the population growth can be discussed and possible action plans can be developed.

Teachers, as well as students can use the information super highway to gain knowledge about other countries' population and resources. Teachers can help students with problems and decision making on a daily basis. The investigation of world population will raise the level of awareness, so that we can learn to handle problems based on data. This data can help us to analyze our situations in a practical way.

Teachers, students, parents and other stakeholders can look for trends in the population explosion. They can hold community meetings at school to discuss how this issue presents a challenge to the big picture of human population on the planet "Earth".

Lessons Plans

This year the ideas that I present for lessons plans will involve several hands-on activities that will promote problem solving and critical thinking skills.

Lesson Plan I

Overview: The purpose of this lesson is to illustrate the concept of population growth rate.

Material Needed: World Population Data Sheet to find the birth and death rates.

Do This: Ask what is the birth rate for the world? And what is the death rate?. Have students find growth rates for two different countries or regions.

Lesson II

Population growth occurs when the birth rate exceeds the death rate. Tell students worldwide, the human birth rate is currently three times the death rate


This activity demonstrates the relationship between birth and death rate and of population growth within a finite space.


1. Fill a bucket with water and add food coloring so it will be more visible in a clear container. Place the empty, clear container with the towel under it in front of the class.
2. Ask for two volunteers from the class to assist. Designate number 1 for one student and number 2 for the other. Each student should tape the appropriate number tag to the student.
3. Hold up the clear container: This will represent the world, and the colored water in the bucket will represent people. Number 1, will add people to the world by pouring dippers of water into the container. Number 2, will be taking people from the world by scooping water out of the clear container and pouring it back into the bucket. At this time, the world's birth rate is three times the death rate. Based on that fact, who should receive the large dipper? Who should use the small dipper?
1. Why did the water level rise steadily
2. What would this mean if the clear container really was the world?

Lesson Plan III

Overview: In a society where tradition often clashes with modern ideology, decision making may be taxing.

Goal: To act out the decision making process of a married couple in an urban area in Connecticut discussing whether or not they will add another child to their family.

Objective: student will (1) discuss attitudes affecting family size in Connecticut; (2) make a decision after listening to opinion.

Skills To Be Developed

1. Role Playing
2. Persuasive speaking
3. Problem Solving
Do This:

Read students a scenario that describes a specific situation involving a decision concerning family size in Connecticut. Choose six students to be the participants in the role playing activity. Select three males and three females and give each student a description of their character. All students who are not role players will pretend that they are the couple who must make the important decision about whether or not to have another child. Poll the students. Did you choose to have another child? Why or why not? What if any particular argument, was the most important in affecting your decision?

Lesson Plan IV


Human population has a variety of consequences, both direct and indirect. One of the consequences easiest to see in our daily life is crowding. With population growth, the average population density will increase. For example, in your three room house an increase from 3 children to 4 children can make a difference. This means that you will need to share your space with other members of your household.

Discussion: talk about the pros and cons of adding an addition to the household.

1. What are the consequences of adding new members to your family?
2. What are the benefits?

Have student imagine that the number of students in your classroom has doubled. Have them list the effects of this. Make sure that both positive and negative impacts are discussed. Have students vote by secret ballot on whether they would like to have more, fewer or the same number of students in the class as they have now. Tally and announce the results to the class.


1. What services are easier to provide for an area of high population density?
2. What qualities are desirable about areas of lower population density?
3. If population continues to grow locally, what is the impact on population density?

Lesson Plan V.

Here's Your Dilemma:

You love children and would like to have a large family. You are aware, however, that the world's population is expected to double in the coming century. You are also aware of the financial and environmental cost of a large family. What would you do and why? Would you:

1. plan to have a large family
2. decide not to have children
3. limit yourself to one or two children
4. get involved with youth groups scouts, tutoring, teaching, etc. emergency foster care, to still be around groups of youngsters.
5. Others
