Description

Human Population and Toxins Resource There are different perspectives on human population growth and the dynamics associated with population change. Go to CIA World Factbook website (https://www.cia.gov/library/publications/theworld-factbook/rankorder/2119rank.html) and choose one developed (not the United States) and one developing country and compare the following and answer the questions: Developed country (Developed country is a country which has an effective rate of industrialization and individual income)

Developing country (Developing country is a country which has slow rate of industrialization and low per capita income)

Population growth rate

0.15%

2.38%

Birth rate

8.4 % per 1,000 people

37.6 % per 1,000 people

Death rate

10.6 deaths per 1000 people

13.3 per 1,000 people

Net migration rate

3.8 migrant per 1,000 people

-0.10 migrants per 1,000 people

Each question should be answered in a minimum of 200 words. 1. Why do you think the population is increasing or decreasing for that country? Try to explain at least two reasons as to why this is happening? (Please refer to your textbook) The two reasons why the population is decreasing is because of war and poverty. With groups such as Isis and local warfare that are uncontrolled, it makes it difficult to maintain a healthy growth in population. These groups and organizations that support terrorism are stealing the resources needed to sustain life. The young people in cities and towns experience their youth being taken away from them and traded for slavery of many kinds. Most of them are also being killed once they no longer need them for the services they were intended to be used for. The value of life or need to nurture does not exist within these groups. These groups focus on acts of violence which results in poverty and war. They control job opportunities for the population which gives them control leaving the people to rely on these

groups to provide for them. This ends up being a vicious cycle and a resource for the weak population. They end up relying on them and cannot break free of them. 2. How do diseases affect the population? Can you think about any diseases that has affected the human population? (Please use peer reviewed sources to support your answer). Diseases affect the population because of people dying, newborn deaths, infertility rates or sum of fertility rates, migration, urbanization, natural increase, population growth, life expectancy and crude birth rates. A disease that has affected the human population previously has been Hansen’s disease also known as Leprosy (Weisz, 2018). This disease has a long history of religious significance being mentioned throughout the Bible. Jesus was mentioned to heal carriers of Leprosy. Leprosy is caused by bacteria called Mycobacterium leprae (Galhotra, Panigrahi, and Pal, 2019). This disease is not fatal but affects population because it is contagious if not treated. Leprosy has incubation periods averaging from two to twelve years. The disease breaks down in forms such as Tuberculoid and lepromatous. The symptoms of this disease causes discoloration of the skin, can spread throughout the body and can affect internal organs. Leprosy remains a raging persistent enigma and is a reminder of social inequity in health, and yet the country is a long way from eliminating leprosy (Galhotra, Panigrahi, and Pal, 2019).

3. Looking at the countries you compared, what are the toxins present in the environment that impact human health? Provide one example for each country.

Jordan, a country in the Middle East is highly affected with chemicals. This is due to toxins that are present in the environment and are highly impacting human health. Chemicals are released in landfills. Jordan contains eight chemical plants, these produce 31.5% of the country’s chemical waste. The chemical plants are based in Karak, Maan, Tafileh and Aqaba. These plants mainly produce paint and fertilizers. In the Hashemite Kingdom of Jordan, six of the plants are medium risk for the environment and two are high risk. The particles that are released in the air can cause the population to be ill. The symptoms are chronic respiratory illnesses to lung cancer, cardiovascular disease and allergies (Al-Hwaiti, Matheis and Saffarini, 2005). Lead is a toxin that continue to be present in the North American air. Compared to the United States, Canada releases about more than 13 times more lead in the air. From 1983 to 2002, the concentrations of lead in the atmosphere have decreased by 94%. The decrease is mostly because of fuel companies switching to non-lead fuel. In 2002, electric and metal facilities have released 42.4kg of lead in the environment (Research Findings, 2005). The lead affects populations such as children neurologically and adults with cardiovascular problems.
