1. Essay on World Population 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). The first country to adopt a...show more content... 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 ...Get more content on HelpWriting.Net...

3. 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 ...Get more content on HelpWriting.Net...

5. World Population Essay 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 Putemún and other ...Get more content on HelpWriting.Net...

7. 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 the future 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.
