Human Population Growth – slow impact – causes and solutions

The effect of Human Population Growth is becoming a serious problem nowadays. Solutions are more than welcome these days. Many organizations and individuals around the world are trying to find an appropriate solution in order to solve today’s most real problem. This blog-post is going to exhibit some arguments, causes and possible solutions to Human Population Growth. Individual’s views are also going to be included into this blog-post, such as Hans Rosling’s talk (TED Lectures) and other. The main idea is to expose reasons of solving Human Population Growth problem.

A hundred years ago, in the beginning of the 20th century the entire world population was less than 2 billion people.
Today the current world population has exceeded 6 billions.

World’s most populated countries are:

  1. China – 1,330,044,544
  2. India – 1,147,995,904
  3. United States – 303,824,640
  4. Indonesia – 237,512,352
  5. Brazil – 196,342,592

The Human Population Growth causes problems worldwide. It does not matter if it is a country or city in North, or South America, East or West Africa continent, Europe or Australia, all of the countries experience problems somehow. As an example, the Population Growth in China might cause problem to the world as a whole. The world is running out of food and fossil fuels reserves, and in a sense the population growth is the reason of it. As number of population increase as large the problems are. Therefore, a country of China brought into power a law to “ONE CHILD POLICY” that prohibit family having more than one baby, as well as prohibition to having a girl infant.

According to Cassandra’s views on the current situation we can state that these people are also called pessimists, catastrophists and doomsayers. Therefore, the main argument confirmed as one by Cassandra’s view is that growth in numbers of people and material consumption rates will inevitably lead to environmental and social catastrophe. As I mentioned above, the world is running out of food and fossil fuels day by day.

On the other side we have a group of people that assert the opposite. Cornucopian’s views are different than Cassandra’s. They

consider that human ingenuity and free markets will allow human species to adapt to any conceivable pressures caused by growth of the human activity. These people are recognized as optimists. This group of people believes that humans are able and will survive under any particular circumstances. The world has already found the way to continue to exist if the planet becomes overcrowded, the Cornucopian’s followers assert.

In my point of view, I must admit that I certainly follow the Cassandras view. I will also take a brief and simple example of how things work according to the Human Population Growth. We all live in a planet called Earth. Since the existence of the world the human being was supposed to feed in order to survive. Therefore, nowadays, as we all are aware world’s reserves tremendously expire, and our acknowledgment teaches us that no human being can survive without food and water.  I also included a picture of DRY EARTH which means that nothing can keep on growing without water as well.

The prediction from 1970’s made by Paul Ehrlich and the famous model equation IPAT which describes the Environmental Impact “I” then “P” population, “A” affluence and “T” technology.  This model identified the population growth in the early 1970s as the most important factor of Environmental Impact. Paul Ehrlich was one of the well known ecologist and prominent environmental thinkers at that time who wanted to inform the world of the overcrowded consequences of 20th century. The model of IPAT became important for examination of economical, environmental factors in many institutions.

Hans Rosling

Hans Rosling is Swedish medical doctor, professor and public speaker. He is born in 1948, and he was studying public health at St. John’s medical college. He also gives a lot of speeches and presentation for world on issues such as agriculture economic development etc. Today he is using Trendalayzer software to present today world situation.

He impress not only me but I thing everyone when he said that all countries in the world progress equal not only in economic view but also in population growth.

Increasing the cost of food.

The purpose of this assignment is to see how EF can be affected by different factors such as food distribution, gasoline, transportation.

Define what EF is?

“The amount of productive land appropriated on average by each person (in the world, a country, etc) for food, water, transport, housing, and other purposes is called EF.”

Briefly explain how food produced at distant places contribute to EF?

The food that is in distant places pass through long way to reach to the market to be sold. They are spending more time and also they are spending more gasoline then the producer that are producing in that neighborhood.

As food production became more industrialized during the 20th century, several trends emerged. One trend was a loss in the number of varieties of crops grown. A second trend was the increasing amount of energy expended to store food and ship it to market. In some countries food may travel long distances to reach the market. In, food travels an average of 1,400 miles from the field to the table. The price American pay for the food covers the cost of this long-distance transportation, which in 2004 was approximately only one dollar per mile (1.6 km).

Assuming that you are an American (not all of us are in this class), you live in New York City (2009 population estimate 8,363,710), and that the average American eats 1 kg (2 pounds) of food per day, calculate the food transportation costs for each category in the table below (U.S. 2009 population estimates 307,006,550).

Consumer Daily Cost Annual cost
You $1.40 $511
Your class 28 10220
Your town (New York) 11.709 4273.85
United States 429.809 156880.34


1.      What specific challenges to environmental sustainability are imposed by a food production and distribution system that relies on long-range transportation to bring food to market?

2.      A study by Pirog and Benjamin (2003) noted that locally produced food in the U.S. traveled only 80 kilometers (appx 50miles) or so to the market, thus saving 96% of the transportation costs. Locally grown foods may be fresher and cause less environmental impact as they are brought to market, but what are the disadvantages to you as a consumer in relying on local food production? Do you think the advantages outweigh those disadvantages?

3.      What happened to the gasoline prices recently? How would future increases in the price of gas affect your answers to the preceding questions?

 4.      If you are an American, how do you think these figures apply to other countries or your country? Where do you base your assumptions?

Pirog, R., and Benjamin, A. (2003). Checking the food odometer. Comparing food miles for local versus conventional produce sales toIowainstitutions.Ames,IA:LeopoldCenterfor Sustainable Agriculture,IowaStateUniversity.


1)      The first question explains the need of transportation of food, from the place where it is produced to the place where people are supposed consuming, for example the case of Carrefour market. In this case, the food selling in Carrefour has been produced on other place so in order to be brought to the market it has to be transported, which means that environment is getting the pollution from the transportation vehicles.

2)      In my opinion, we have more advantages by consuming the food from our close region, locally grown foods. The market saves the money for transportation, the environment is less polluted because of the short distance between production place and the market, and the food is as the question states fresher.

3)      The gasoline prices increasing rapidly nowadays. I think the reason of this happening is because of the lack of fossil fuel, the world is running out of fuel, and the other reason I think is the riots around the world, especially in countries rich with fuel resources such asLibya,Iraq,Saudi Arabia, and some other African countries. In future, I think the world is going to face a lot of problems with this issue because of the reasons I mentioned before. However, the problem can be solved by improving the other natural resources, such as sun energy, that takes a huge step recently, and the usage of electric cars, according to the transportation issue.

4)      Well, If I was an American instead of a citizen if FYROM the situation would be different. People inAmericaare closer of getting some benefits from the government than people from my country. For example, If you  like to start operating some organization that deals to natural environment saving, you will not survive, because the government at first will not get your porpose for real and second you will not survive because of the financial situation within the country’s economy. People are more interested of surviving the current day, instead of getting involved in some organizations that deals with sun energy or saving the nature. In the other side, people In America are well situated economically so they are able of doing things like these.

Assignment 2

Eastern Island vs Tikopia


Easter islands get the name from the first European visitor. Easter islands are located in Pacific Ocean. This islands is characterizes for monumental statues, the large stone statue is called moai, and this statues are created by Rapanuie people. This statue made this island to be famous and today is most visited place in world. Easter islands are small with population about 2000 people. This island is 2000 miles from the near population center and is one of the most isolated places on planet. Before people to start using trees for there needs like building boats for catching fish and using trees for fire this islands was full with trees. I should mention also that now Eastern Island has limited natural resources and it has a few trees. Natural resources that can be found today on Eastern Islands are: iron, nitrates, some metals and molybdenum. Also in this Island they have agricultural industry and they are producing potato, bananas, sugar, onion melons and other products.

When we should compare Eastern Island with Tikopia we can see that Tikopia has flourish environment last 3000 years. In Eastern Island and some other Island we do not have the same environment like Tikopia because the expertise proves that there is a lot of soil replacement. Those are the environmental factors but also there are some cultural factors. One of the habits that citizens of Tikopia were limiting the slash and burning cultivation and using intensive agricultures garden plots. Also other thing is that people that where living in Eastern Island doesn’t care about trees. They where using trees for fire, and to build boats to be able to go in see and catch up fish. They didn’t care about there natural resources particularly for trees. From these two islands we can conclude that people that where living in Eastern Island didn’t take much care about there natural resources and people who live In Tikopia take care about there natural resources.

Assignment 1

About me


My name is eco110rope and I am studying at the American college of Thessaloniki and my major is Management. I am coming from The Former Yugoslav Republic of Macedonia, one town called Stip and this is my fifth and hopefully last year in this college.

The purpose of my blog is to get in touch with other students, read their blogs see how they thing, and also they can read my blog and see how I am thinking.

Like I mention before I am living in Stip. In Stip we have two rivers one is Bregalnica which is the second big river in FYROM and the second river is Otinja. Otinja is the rivers that divided the town in two parts. Also I should mention that we have very hot summer and when it come winter is so could and we have a lot of snow.

Stip is developed city, and it is now for building industry and textile industry. Those two industries don’t polluting our environment. But i should mention that in the city where i live we have one factory for oil that pollutes the river Bregalnica. I mention before that Bregalnica goes from Stip and this part from the river is so polluted.
