As we grow older we think about all the potential issues within the world. Many different things may come to mind when we think of the future, our children’s futures as they become adults, the children whom are not even born yet and our future as we grow old. We also think about what the world has already overcome and what we still need to overcome. Some choices society has made have been positive, some negative. What is the largest problem we may face in the future and how will this impact us? The increase of population will affect the world over the next ten to twenty years by increased carbon dioxide emissions, employment opportunities will be reduced and the increase of poverty.
Carbon dioxide emissions will increase which will put our recourses at jeopardy. As we all know, humans need oxygen to live. Burning of fossil fuels, such as oil, coal and gas, increase the carbon dioxide within the air and reducing the oxygen levels. Our dependence on fossil fuels combined with the global issue of climate change alternatives need to be used (Writers, 2007). To reduce emissions the population can turn to solar power, wind power and geothermal energy.
With the population growing more people are in need of income but employment opportunities within the U.S. are decreasing. Statistics show only Latin America is the only country reporting healthy job markets, while the U.S., Japan and Europe have higher unemployment rates (Business Recorder, 2012). With population rising all over the world, all countries will need to figure out how to produce money for society. One might think that increasing public spending by just 1 percent may improve the job rates.
As the population grows and employment opportunities drop the poverty level will increase because families will not be able to afford luxuries. As families are unable to obtain employment they will begin to cut costs and

Population Dynamics

...the effect of changing lambda (λ) in the discrete model, and r in the continuous model? What is the effect of changing N0 in both models? (2 marks) When in discrete mode, a change in lambda (λ) will change the growth rate of the species. If λ increases, so does the growth rate and if λ decreases, as will the growth rate. However, the growth rate only increases if the number is above 1. 1 itself indicates no growth and below one is negative growth. The same principle applies to r. However, as apposed to 1, 0 is no growth while below 0 and above 0 is negative and positive growth, respectfully. Figure 1 and 2 show a stable, increasing and decreasing population for both continuous and discrete growth. Question 2. What are the differences between the discrete and continuous models of population growth? (2 marks) Discrete growth shows a type of growth in populations that have seasonal breeding seasons (Alstad, 2001). This means the percentage increase can be added after the season to the group. Continuous growth means that the growth of the population is continuously growing without seasons and has overlapping generations. An example of discrete growth is figure 1 and continuous growth in figure 2. Figure 1 Note that the dots are the changes in population after the previous, this graph could also show horizontal lines from one dot to the point in t matches with the above dot. The vertical line from the horizontal dot and dot further along t show the change in population (Otherwise...

Over Population in India

...meaning of OVER population explosion is “a pyramiding of numbers of a biological population” (Webster’s dictionary). The main factors affecting the population change are the birth rate, death rate and migration. Migration is the number of people moving in (immigration) or out (emigration) of a country, place or locality. The population change is calculated by the formula: Population change = (Births + Immigration) – (Deaths + Emigration) India, being a developing country, has had to face several economic and political challenges. One of the most important problems is the population explosion. India's population hit 1 billion in May 2000, increasing the urgency for the country to take steps to control its population growth. Some of the reasons for this population explosion are poverty, better medical facilities, and immigration from our neighbouring countries of Bangladesh and Nepal. The population density of India in 1996 was about 287 persons per square kilometre. Several solutions to decrease the rate of population increase have been tried by the government, some successful, some unsuccessful. Although the rate of increase has decreased, the rate has not reached the satisfactory level yet. The population in India continues to increase at an alarming rate. The effects of this population increase can be felt in the increasing poverty, unemployment, air and water pollution, and shortage of food, health resources and educational resources. The main reasons, effects and foreseeable...

...Population Growth – Exponential and Logistic Models vs. Complex Reality I. Exponential Population Growth 1a. Suppose a single bacterium is placed in a flask that contains lots of food for bacteria. In this flask, each bacterium grows and divides in two every 30 minutes. Therefore, the number of bacteria in the population doubles every 30 minutes. How many bacteria do you think there willbe by 5 hours after the single bacterium is placed in the flask (just guessing)? ______ 1b. Complete the table to calculate how many bacteria there will be at each time. 1 bacterium at the beginning = 0 minutes bacteria by 30 minutes bacteria by 1 hour bacteria by 1 hour and 30 minutes bacteria by 2 hours bacteria by 2 hours and 30 minutes bacteria by 3 hours bacteria by 3 hours and 30 minutes bacteria by 4 hours bacteria by 4 hours and 30 minutes bacteria by 5 hours 2.Plot the number of bacteria at each time; connect the points to show the population growth. Number of Bacteria Time (hours) 3a. How long would it take for the population of bacteria to increase from 1 bacterium to 500 bacteria? 3b. How long would it take for the population to increase from 500 bacteria to 1000 bacteria? Notice that, when a population doubles in each time interval, the number of bacteria in the population increases faster and faster as the population gets larger. This kind of population growth is called exponential population growth. 4.For these bacteria, population...

Precipition Effect on Evolution

...Precipitation Effect on Evolution Introduction Precipitation can have rapid and lasting effects on an ecosystem and evolution of the life forms throughout the region. Too much precipitation can cause flooding, eroding shorelines, and rising sea levels. The effects of such activity wash away food sources and ultimately changes the way the various life forms will behave and survive. If weather patterns change and eliminate or drastically reduce food sources and habitats, it can bring various elements of the ecosystem to extinction. The route chosen for this lab was to change precipitation patterns and land size moderately for both islands to evaluate how this would affect the finch population and see if either island would be able to sustain a population of finch with excessive rain or a lack of rain. These types of climate changes are happening throughout the world and result in dramatic behavioral adaptation to adjust to the environment. Materials The materials used for this lab were a computer and access to the Evolution Lab that is found on the student website of the University of Phoenix. Methods and Procedures Using the scientific method the research provided background information that two islands have similar variables pertaining to the ecosystem, finch characteristics, and finch population. The question is will a change in the current precipitation pattern have a lasting effect on the finch population? The hypothesis is if the precipitation increases it will erode...

...many countries because the significant increase in the number of individuals being born compared to those who die far exceeds the amount of resources available and the carrying capacity of the country’s environment to sustain ongoing human activities. Overpopulation has a tremendous effect on our quality of life by ways of pollution and global warming, poverty, and the destruction of habitants. Significant population growth in many countries globally take a negative effect on the environment and society due to depletion of resources causing poverty and starvation, major pollution and increases global warming, and displacement of species due to their homes being taken away from them forcefully. Human overpopulation increases pollution by littering, soil contamination and toxins released in the environment as well as carbon monoxide by ways of vehicular mechanisms being used on a daily basis that eventually causes global warming. For example, water pollution caused nearly 20,000 beach closings in 2004 and fine particle air pollution resulted in the premature deaths of over 45,000 people in the U.S each year (retrieved from www.npg.org/effects of overpopulation). Poverty and starvation increases as the population grows because there is not enough food, shelter, and employment to accommodate the number of individuals and their families living in areas that are both less-developed and overpopulated. Currently, more than 66% of the world population is malnourished according to the World...

They have sucking mouth used to eat either terrestrial insects that have accidentally fallen on the water’s surface or other aquatic insects like mosquito larvae as it comes to the surface (National Wildlife Federation, 1996-2013). There are several factors that can change the stability and growth of this insect’s reproduction and population growth. Abiotic factors like water, temperature, and light can change the population but biotic factors like plants or other organisms can alter it also. If change within an environment happens then change to the organisms within the environment will happen as well (Elzinga, 2004). Abiotic Factors Abiotic factors are non- living components like water, temperature, and light. A rapid increase or decrease in any of these factors would have an effect on this species. Water is important to the water strider population because it is here that it lives and obtains its...

The Effect of Wage Rate and Profit

...overtime, an increase may not increase the working population of the firm as income effect of the increase will mean demand for leisure being high holding expenditure on other costs constant. This will reduce the working population and also reduced output and profit. On the other-hand, with overtime, workers who work only 8 hours will remain in the same wage level but earn more when additional time is spent on work. This will mean extra man hours into production thus increasing output and profit. Income/Wage BC1 From the diagram above, BC1 represents the original budget constraint and BC2 be the budget constraint under with overtime rate which the manager is initiating. The aim here is to increase the working population of firm in terms of man hours needed to produce more pineapple to meet increasing demands. The firm is also a cost minimizing and profit maximizing concern in which the last cedi spent on wages of labour must equal the cost of employing labour for it to be at equilibrium. At point a, workers’ combination of leisure and income yields the maximum utility given the cost (approx 300 cedis) to the firm. However to increase the working population of the firm, the manager initiates a plan resulting in a new budget line BC2. Workers now choose to remain at point a, or progress to a higher IC, IC2 and enjoy maximum utility at point b. For the firm, this means more hours in production and output increases to meet...

Overpopulation

...Population: Population is a summation of all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding. Overpopulation: Overpopulation is a function of the number of individuals compared to the relevant resources, such as the water and essential nutrients they need to survive. It can result from an increase in births, a decline in mortality rates, an increase in immigration, or an unsustainable biome and depletion of resources. Causes of Overpopulation: Decline in death rate: Root of overpopulation is the difference between the overall birth rate and death rate in populations. If the number of children born each year equals the number of adults that die, then the population will stabilize. Population increases due to increases of birth rate for long period of time then death rate. Improvement of agriculture provides nutrition without hunting. Better Medical facilities: Better medical facility is another reason of overpopulation. Science invents different vaccines and treatments for life threatening diseases. Due to this this death rate decreases. Rise in Illiteracy rate: Uneducated people do not know about the harmful effects of overpopulation. They give birth to large number of child and do not provide them the basic needs of life. Technological Advancement in Fertility Treatment: Advancement of technological facilities also play important...

Speak up, there are so many people in here and it is so loud… In analyzing the effects that nose and population density have on the human race, it is not uncommon for people to be affected in many different and negative ways. However, there are a vast number of negative factors that affect individuals in either their work or home environments such as: noise, population changes, territoriality issues, privacy, and personal space issues just to name a few, there can be just as many positive impacts as well. As population becomes denser or increases it is only natural that noise pollution is going to increase too, and along with the increase in population and noise, concepts of trust, privacy and personal space issues increase. The effects of these issues become increasingly negative. However, there are factors within personal environments that increase positive impacts upon individuals, for instance in every city, county and state there are parks, nature trails, zoos, and other wonderful environments within bigger environments that people can utilize to counter balance the negative impacts. Concepts of territoriality, privacy, and personal space are all cognitive processes that portray ownership including; places, possessions, and even people. Therefore, with the growth...
