Population and the Effects on Society and the Environment

As technology and medicine advances, people are starting to live longer due to better medicine and technology created to assist in difficult daily tasks. Due to rapid growth, natural resources are becoming scarce and lack of land causes overcrowding in many areas of the world.


  1. What is Population?

  2. China and India are countries with the largest population in the world. Due to vast amounts of land and lack of contraception, the population is growing at a rapid rate within these countries. Developed countries such as the United States outsource in China and India because the labor cost is cheap. Labor laws in these countries are not regulated which allow these countries to take shortcuts which means more products to export.
  3. Population is the number of people in an area based on specific categories such as ethnicity, age, income, sex, and social economic status. Population is constantly changing due to birth and death rate and migration among families to find better sources of income. Population is measured by counting the actual number of people in a given area and measuring birth to death ratios. Centripetal and Centrifugal forces predicts how successful the country's economy is going to be; many people migrate in or out of the country based on the availability of jobs.
  4. In every unit area, population density is the measurement of the amount of people in a given square mile. In cities, the population is more dense due lack of land; in rural and suburban areas, people own more land and is usually used for agriculture and income. Countries like Russia and Australia have land that is unoccupied due to the structure and temperature which makes in unlivable. Large cities such as New York City and Hong Kong are densely populated; skyscrapers and high rise buildings are prominent in these type of cities because it helps utilize the little space that they have.
  5. The darker areas on this map represents larger populations whereas lighter areas represents smaller populations. Areas that have lighter shades are subjected to extreme weather. The darkest areas represents India and China; these countries attract other countries because of import and export business due to an abundance of available workers. Africa and Australia have smaller populations when compared to other countries of the world because of desert like conditions. Areas with the darker areas have larger population because these are developing countries. There are more resources for people survive therefore more growth in the population. However, even though it is growing rapidly, it doesn't mean the population is healthy. Most of the population that is growing the fastest are the poorest in these countries.
  6. Since the industrial revolution occurred, the population has been increasing rapidly throughout history. Developed countries are seeing increasing trends based on the economic development; the more people are able to provide for the family, the larger the family gets. Countries with lack of industrial development are growing but most are unable to survive due to lack of medical attention and scarcity of water and food. The industrial revolution created income for many people; these people are able to afford shelter and food. Based on this chart, the boom started in the 1900's; during this century, oil and coal were used to power factories and trains which were vital for countries to flourish.
  7. Thomas Malthus and Population Growth
  8. Thomas Malthus was realistic philosopher who expected population to grow in time as long as there's food and shelter. However, due to rapid growth of the population, diseases and scarcity of resources were bound to be seen. I agree with his theory and predictions; if resources are not replenished and medical technology didn't advance, more casualties would be seen. In present day, the population is growing at a fast rate and if resources aren't replenished, people will starve due to over harvesting. Malthus was skeptical but realistic; he saw the positive side of population growth but expected the worst of it.
  9. Since the industrial revolution occurred, better medicine was created which helps prolong life. Sanitation was developed which provided better living conditions and many products were created to assist in making life easy and comfortable. Products that are vital for everyday life was being mass produced to help provide for the growing public; these products include clothing, medicine, toilets, pesticides, automobiles, trains, and common household items. Better sanitation means a decrease in illness; when sewer spews onto the waters and land where people live, diseases spread rapidly and with lack of medical attention, more people are subjected to casualty.
  10. Based on the trend of population growth from the past to present, the growth will continue at even a faster rate in the next few decades. The main problem to this theory is the lack of resources and land for the growing population. The more people there are, the more waste would be produced. Ways to alleviate future problems is to educate developing countries and provide contraception to areas that have larger population growth. Other ways include creating sustainability laws, monitoring natural resources, and replenishing what was taken out of the earth. Educating the general public about major issues due to overpopulation and pollution can help prevent future disasters. Increase awareness of contraception and becoming environmentally friendly would shed light to our future.
  11. The Census bureau gathers data regarding the world population, demographics, and economics. These data collection is done annually to every five years. The information gathered helps economists predicts trends that are vital for the economy. However, the census is not entirely accurate but it helps give professionals an idea on where the population of the world stands. The world population clock is a real time clock measuring the growth of the population when factoring birth and death rates. Since the census data is not accurate, there are many other reports officials can conduct to receive a more accurate reading. Each country should have a department that is in charge of retrieving counts of births and deaths per town; this would deem difficult because it would cost too much to hire people to retrieve this information.
  12. The Science of Overpopulation
  13. Overpopulation is a major problem that is have serious consequences. For every four people that are born, two are dying. One person would need an acre to survive on a daily basis. The ecological footprint that we leave is massive because of where products we consume are from and where waste is going. As the population grows, the more land and resources are going to be used up; waste and agriculture would affect untouched pristine wilderness due to the demanding needs of human consumption. Due to better medicine and mass production of food, more people are living longer. Developing countries are producing more babies due to lack of education and contraception; whereas, developed nations are producing less babies. Based on the rate of population growth and the major consequences that deems detrimental to the environment, the government may have to implement policies like that of China's one child policy to reduce population and protect the environment.
  14. Although population growth can be detrimental to the environment, there are many positive aspects to this as well. There would be more people to join the workforce which could help boost the economy. Technology has advanced and will continue to, to serve the growing society; genetically modified crops and livestock allows for these industries to produce products at a faster pace. However, due to the genetic modifications and over use of pesticides and fertilizers, it could be harmful to the health of the consumers and environment. Population growth indicates that medicine and technology advanced and will only continue to advance. There are very little ways of stopping population growth; officials can provide education to the public on health and environmental awareness and sustainability to reduce detrimental affects due to overpopulation.
