World Population
Works Cited Not Included
Population causes a heated debate among many people. The world's population has exceeded 6.5
billion and continues to increase about another 76 million each year. The three most populated
countries are China, India, and the United States. Scientists have become worried that the population
will double within the next 50 years, exceeding 12 billion people. With scarce natural resources and
the strain that a doubling in population will cause on food availability, people become more wary
about population control. What is population control? Population Control is the practice of limiting
population increase, usually by reducing the birth rate (www.wikipedia.org).

Samuel states in his article, "The Development of India's Policy of Population Control": "This policy
has not yet received the attention merited by its importance for India's development."
China leads India in population by about 2 million people, putting China at the top of the list with
1.3 billion people, roughly 20 per cent of the world's population (www.wikipedia.org). What has
China done in the effort to slow the ever growing population? In 1979, China introduced a policy
limiting one child per family. This was unprecedented. In 1986, the limit increased to two children
per family, as long as the family was non–Han. (Han is the ethnic majority in China). Some rural
Han families were also allowed to have two children, as long as the firstborn child was a female.
The goal in doing this was to limit the population to below 1.37 billion by the year 2010. Some
families refused to adhere to the family limitation policies. For example, they sabotaged government
mandated contraceptives and paid doctors to claim to have performed abortions.
It has been 28 years since the policy was set, and there have been some gender fluctuation within
the Chinese population. At first, the Chinese families only wanted male children in order to carry
on the family name and honor. Many families with daughters born wanted abortions or simply
killed the females after birth. In 1995, 1,166 male children were born for every

2. World Hunger Essay
World hunger has been a constant problem throughout the ages. It is a problem that should be able
to be solved easily, yet there are still 1.02 billion undernourished people worldwide. With the world
population being 6.7 billion people, and the Earth producing more than enough food for this amount
of people, why is it that there are hungry, malnourished people all around the globe?
Hunger is caused by many events, including the poverty trap, natural disasters, war, poor agricultural
infrastructure, and over–exploitation of the environment. The poverty trap is the cycle of poverty
that can begin from a limited diet and progress to birthing a baby that is malnourished. This causes
the baby to have slower development and poor...show more content...
They do this by destroying local markets and seizing or destroying crops and animals, while
contaminating wells and mining fields. This forces farmers to leave their lands and usually begins
their cycle in the poverty trap. Poor agricultural infrastructure causes hunger because the lack of
roads, warehouses, and irrigation causes higher transportation costs, a deficiency of storage facilities,
and unreliable water supplies. To improve the agricultural infrastructure, however, it would cost a
profuse amount of money, which would put the country in greater debt and result in less funding for
essential systems, such as health care, which already has too little funding. Over–exploitation of the
environment is caused by deforestation, over–cropping, poor farming practices, and overgrazing.
When over–exploitation occurs, salination, erosion, and desertification results, causing less fertility
and more hunger across the globe. Salination is caused by erosion that strips the earth of its
nutrients, leaving behind salty, unfertile land. This causes plants to have less of a chance of
growing properly, or not grow at all. When less plants grow, less people are fed, and more go hungry.
From 1970 to 1997, humanity was solving the starvation problem worldwide. The amount of
hungry people had dropped from 959 million to 791 million, which is a total decrease of 168 million
people. This decrease is

According to the Population Division of the United Nations, world population reached 6,500
million in 2005 and will continue growing by more than 76 million per year, United Nations
estimates indicate that by 2050 there will be between 7,700 million and 10,600 million, being the
most likely projection of 9,100 million inhabitants. The availability of arable land and increased
efficiency in food production from land can reach their limits. The oceanographic conditions,
climate and its effect on soil quality and various human uses to determine crop land will be unable
to provide food for the ever growing human population. On the other hand, it is recognized, therefore,
that marine and freshwater aquatic, covering over 70% of the planet's...show more content...
In 2000, the salmon produced more than 1.1 million tons or 61% of the total production of
salmon in the world. This trend is particularly evident in Norway, where the combination of
reduced availability of wild resources and sustained increases of crops has resulted in the
production of farmed Atlantic salmon is 100 times higher than the wild catch. In Canada, the
decline of natural stocks of Atlantic salmon and Pacific has led to severe restrictions on the catch
of wild species. In Chile, growing sustainably salmonid species has increased, reaching in 2000
27% of world production exceeding (52%) the value of exports of fishmeal and other marine
products.
In Chile within the various aquatic species on which extractive activities are carried out and
cropping, the mussels are second in the national harvest totals (18%), this group being represented
by the species' giant mussel "(Choromytilus chorus), the "mussel" (Mytilus chilensis) and "mussel"
(Aulacomya atra) (Subpesca, 2006) (Fig.1). The development of the mussel, which represents the
oldest farming activity has been developed in Chile, since there are reports of field trials from
1968 (Yanez, 1974), was initiated breakdown product of the fisheries of these resources, as the near
extinction of "choro shoe" and the depletion of the natural banks of the "mussel" and "mussel." The
greatest success is achieved in the cultivation of "mussel" in PutemГєn and other

4. Population Growth Essay
Population Growth
Population Growth is becoming a huge issue in our country and world today. The reason that it has
become such a pressing issue is that our growing population needs a growing economy and has
growing needs. As our population grows, the needs of the population become bigger. Very large
population becomes a problem when there isn't enough space to live, and not enough food and
supplies to live off of. We can predict population size in thefuture by examining the recent past.
This can give us good ideas about what we will have to do to accommodate all of the people in the
US and the world, or start to put restrictions on babies being born like our fellow country China. In
this activity we were given the...show more content...
The errors in the linear model were random, but not off by much each different year. The population
wasn't off by more than 2,000 people at most in one year. Using the linear model we made some
predictions like what will the population being the year 2000? By putting the equation into the
calculator and going into the table, we predicted that in the year 2000 the population would be 2.76
billion. Another prediction that was made was what will the population be when I retire. Most people
retire when they are about sixty– five, so that would be in the year 2045. The population in 2045 is
predicted to be 3.8 billion according to the linear model. The population will double from the
current population in the year 2114. The population will then be 5.52 billion. One thing that I am
concerned about is how high the population will be when my children are growing up. I plan to
have children when I am about 27 so when my child is about 20, the year will be 2027 and the
population will be 3.4 billion. Next we did the same procedure for the world population. In this case,
the exponential model fit the data more efficiently. The equation was 2,552,666,405 =
1.018,677,273^x, r = .998328246. The world population for the year 2000 is will be 6.44 billion.
Upon retiring the world population will be 1.5 trillion people. Comparing the two models the
exponential model makes sense because the population is growing at such a rapid rate. The
