Increasing human population numbers are putting great pressure on our environment, people can affect environment and vice versa. Atmospheric quality, energy flow, water cycle and recycling all causes by human and can influence them. So how human activities can affect our ecosystem? What is the ways that global warming might affect our ecosystems? Is our local ecosystem affected more or less than other parts of the world?
Local and surrounding ecologies and environments with specific factors:
North Central Texas has a humid subtropical climate with hot summers and winters that are not extremely cold. High elevation areas in the "Upstate" area have less subtropical characteristics than areas on the Atlantic coastline. In the summer, North Central Texas is hot and humid with daytime temperatures averaging near 90 °F (32 °C) across most of the state with overnight lows near70 °F(21 °C). Winter temperatures are much less uniform. Coastal areas of the state have very mild winters with high temperatures averaging near 60 °F (16 °C) and overnight lows near38 °F (3 °C). Further inland in the Houston area, temperatures average between 50 °F (10 °C) during the day and32 °F (0 °C) at night. There’s really nothing around me but schools and police department, which is called the Collin County Sheriff Department and there are some forests near to my local.
How human activities affect our ecosystems:
Human activities are altering the equilibrium involved in the natural processes and cycles, if these changes due to human activities are not addressed. The stability of the world’s ecosystems may irreversibly affect. This how we affect environment:
We damage ecosystems by harvesting trees that are homes to hundreds of different organisms.
Many sources of energy are polluting the land, the air and sending CO2 into the environment.

Human Population Growth

...Assignment: Human Population Growth There are two types of population growth and they are expressed in the form of models explaining each theory. The exponential population growth model describes population’s expansive capabilities to an unlimited size and scope. Each generation is calculated using specific factors to formulate the amount of population growth by the births and subtracting deaths over a specified period of time. The rate of a population relies on the growth of the population groupings that are calculated. A population’s size can be greatly reduced or increased by environmental factors. For example, if there is a drought or severe cold weather, population increases can be greatly reduced because of the lack of necessary resources such as food and water. The lack of competition for certain food sources, because of reduced populations, can have the reverse effect on other animals and their populations can be increased. Even though exponential growth is possible, it is not sustainable because eventually the populations will consume all resources that are necessary for the continuing of the species. The logistic population growth model describes the reality that natural environments do have limits to their natural resources that benefit population growth. These limits keep species populations in check and allow only a certain amount of individuals to live successfully in any one environment. The growth rate of populations, in the logistic model, decreases as...

Human Population

...Human population and growth Introduction Humans like other organisms, must find food, shelter and a place to breed. The first humans were hunter-gatherers who moved from place to place, taking what they needed to satisfy these requirements for survival. After events such as the Ice Age, their method of living became more difficult and humans began to settle in the most suitable areas. Therefore, the amount of humans started to increase creating the need to create census. Census is procedure of systematically counting the members of a given population to control their requirements for living. Even though the human population growth began to be controlled effectively, a lot of environmental factors and situations such as revolutions altered this method. An ecologist can study how any factor affects the size of a human population by taking samples and counting the numbers of organisms in a particular habitat. These factors may be biotic which means living or abiotic which means non-living. Together they affect the rate at which a population grows, and also its final size. All factors that affect the population growth make up the environmental resistance. Some of these factors are: food, predators, temperature, oxygen availability, parasites, light intensity, competitors among others. When a small population begins to grow in a particular environment, the environmental resistance is almost non-existent sometimes the environmental resistance limits population growth...

...Human Population Growth Exponential Growth of a population has a continuous birth rate through a period of time and there is not any affect due to their needs getting met as far as food. There is not any disease affecting their bodies. Logistic Growth can cause a population to be restricted by a lack of food and predators and disease. Overcrowding cause unbalance in the environment to support every needs it cannot supply everyone needs. In logistic growth when the environment reaches its carrying capacity. (Britannica 2012) There are numerous factors that hinder a logistic environment such as disease, birth rate, economic conditions. Human population has been increasing at a very rapid rate for centuries nothing can really slow down or population other death it helps to keep a balance among our human population or any population. As humans we have a negative effect on our environment due to our daily activities we as human’s par-take in and the way we choose to live. We continue to tear down to build up to support our life style of today. Convinces of indoor plumbing, and electricity and the new life styles we now live. I have to take in consideration the affect it have on our wildlife our forests and just the breakdown of how nature replenish the earth on its own.

Human Population and the Environment

...Human Population and the Environment SCI/275 12/22/2013 Urbanization is the movement of people from rural areas, such as country sides, to urban areas, such as cities. Cities like Los Angeles did not come to be the way it is simply overnight of course, urbanization is also the transformation of rural areas into urban ones. According to the text book, “When Europeans first settled in North America, the majority of the population consisted of farmers in rural areas. Today, approximately 79 percent of the U.S. population lives in cities” (Berg, Ch. 7.5). One more important distinction between rural and urban areas isn't how many people live there but how people make a living. Most people residing in rural areas have jobs involving harvesting natural resources—such as fishing, logging, and farming. In urban areas, most people have jobs that are sites of industry, economic development, and educational and cultural opportunities. There are factors that produce urbanization. The four major factors that affect population are the death rate of the people versus the birth rate of the people in that urban population and the immigration rate (people coming in), versus the emigration rate (people going out). These factors determine the rate of the population decline or growth. If the birth rate and immigration rate is larger than the death and emigration rate the population will grow exponentially. If the death rate and the emigration rate is larger than the birth and immigration......

Human Population

...Human Overpopulation Not that long ago, humans were still struggling to survive in a world plagued with diseases, predators, and unknown dangers. The harsh natural environment functioned to keep our population growth in check. However, since the last century, the human population had grown exponentially. Our survival is no longer threatened by other species and harsh environmental conditions. In fact, there is a new concern for the modern society—overpopulation. According to The American Heritage Science Dictionary, overpopulation is “The population of an environment by a particular species in excess of the environment's carrying capacity”. In addition, “the effects of overpopulation can include the depletion of resources, environmental deterioration, and the prevalence of famine and disease”. In the case of human overpopulation, human is the species that is in excess of the Earth’s carrying capacity. If human overpopulation is in fact a legit concern, then the effects mentioned in the definition above would most likely follow in the distant future. In order to prevent the negative consequences of overpopulation, humans must understand what specifically caused the population growth, how does population growth affect the world, what are the implications of overpopulation, and how to mitigate the effects of overpopulation. Although our population is a huge number compared to what it was in the past, we cannot conclude that we are overpopulated based on that comparison. In...

Environmental Science and Human Population

...Environmental Science and Human Population Worksheet 1. What would you include in a brief summary on the history of the modern environmental movement, from the 1960s to the present? The modern environment movement began on April 22, 1970 largely due to the release of the book The Silent Spring that is written by an environmentalist name Rachel Carson. Overtime, I think the environment has improved tremendously from where and how it all began. With the help of the National Resources Defense Council, many things started happening for the betterment of the environment. Many Acts and laws were passed such as the Environmental Protection Agency, the Clean Air Act and the Endangered Species Act. The National Resources Defense Council has created acts and laws that have help to stop the mistreatment of the environment as well as the senseless killings of some of our wildlife that are still effective to this very day. 2. Explain the primary concern over exponential population growth. What promotes exponential population growth? What constrains exponential population growth? The primary concern over exponential growth is, the more people there are and the more resources we use will eventually lead to the Earths downfall thus leaving us with a weak environment. The population on Earth has grown over the past few decades and with that, growth come the more frequent use of unnatural resources. There are more people using and trying to advance technology and while it seems like a...

Human Population

...Human Population Is our planet getting too big? “Go Forth and Multiply!” That is what the human population has been doing successfully for thousand and thousand of years, expanding, exploring, migrating, conquering, utilizing, evolving, civilizing, industrializing, and now we are destroying the very land upon which we live. (Anup Shah) There are over six billion humans living on this planet and the numbers will continue to grow due to the birth rates and that humans are living longer so the death rates have declined. With the humans that inhabit our planet we will consume vast quantities of food and water, use a tremendous amount of energy and raw materials, and produce much waste which is harmful to our environment. If this trend continues to keep up at this pace we could end up using up our natural resources not to mention how much waste we will continue to accumulate because we are not recycling how we should. Not only will we end up using any available land it will cause havoc on the wildlife, which inhabits the land. With the humans using up the land forcing the wildlife out of there natural habitant we will start seeing more conflicts with animals and humans. The United Nations, which periodically publishes population projections for the twenty-first century have come up with some startling numbers, they have figured that in the year 2050 the world population will be between 7.9 billion (low estimate) to around 10.9 billion (high estimate), but most likely there......

Human Population Growth

...Human Population Growth SCI/230 October 26, 2014 The world population growth is defined very simply as the number or estimated number of total births in a given period, usually a year, minus the number of total deaths. The difference between these two numbers tells us how many people are being added to the world population each year. The growth rate is this number divided by the total population and multiplied by 100 to get a percentage. While the world saw an increase in the total human population by more than 80 million in 2010, demographers note that the population growth rate has been declining since the early 1960s. It's in this phenomenon of a declining growth rate that we find the key difference between the two curves. Moreover, one of the two fundamental growth curves proposed to explain increases in human population is the exponential growth curve. This curve assumes that the population growth rate remains fairly constant and that the population will continue to double in an increasingly shorter period of time. It's called an exponential growth curve because it plots the output of an exponential equation. In the years since the early 1960s, observed declines in the rate of population growth -- the percentage of the world population added per year -- began to suggest that population growth is not likely to be exponential. In exponential equations, population growth rate does not slow down, it continues at a constant rate. In the logistic growth curve by......

Action on Ever Increasing Population

...Action on Ever-Increasing Population Name Institutional Affiliation (“Population | Define Population at,” n.d.), defines population as the overall number of people who reside in a given area, region, state or a country. However, the ever-increasing rate of population growth is alarming and becoming an issue of concern in nations like India. India has the second world largest population. With the current growth in population levels, India is estimated that it will have the highest population in the world by the year 2030. High populations have its advantages which may include large number of work force. However, high rates of population growth comes with key problems such as lack of and/or inadequate resources, high levels of unemployment, alarming levels of poverty spread, increasing people who are uneducated among many other unforeseen problems. Ajit Singh Katal in (“What shall we do about our Ever-Increasing Population? - Group Discussion,” n.d.), Says that education is the only ways to fight with the emerging problem of overpopulation. The public and the community as a whole should be made to know the consequences of overpopulation. Teenage pregnancy is a major contributor towards the population. South Africa’s president, Jacob Zuma in (“Take babies from teen moms: Zuma - Politics | IOL News,” n.d.), says that teen mothers should be forced to go back to school. The government should educate them until when they......

The Problem of Human Population Growth

EHRLICH, Ph.D.(Kansas) Professor of Biology and Director of Graduate Studies, Department of Biological Sciences, Stanford University, Stanford, California 94305, U.S.A. rather small number that are thought of as 'important' forms of wildlife—will have a dramatic negative feedback effect on the capacity of our planet to support human life. This is because, although politicians and laymen tend to focus attention on air pollution and water pollution as the most serious environmental problems, in fact the most devastating of all is the destruction of the life-support systems of our planet. These are the natural ecosystems that provide us with a series of public-service functions without which we cannot persist indefinitely on this Earth—such functions as maintaining the quality of the atmosphere, controlling roughly 99 % of the potential agricultural pests, recycling of our waste products, and many other services that we cannot perform for ourselves (Ehrlich et al., 1973). The third message which I would like to give you is that the time for research as a major approach to the world's problems is long past. If you are trapped in a forest, downwind from a forest fire, and it is raging towards you at ten or more kilometres per hour, you do not immediately convene a committee to study reforestation—you call for water. In human society, calling for water basically consists of promoting......

Expert Views on Increasing Population

...Expert Views on Increasing Population World’s population growth is close to seven billion, the rapid growth is raising concerns with many experts. Experts today are arguing their views on the issue of population growth. While both Alon Tal the author of “Overpopulation Is Still the Problem” and Robert Walker the writer of “Overpopulation Is Not the Problem? Really?” state that population growth is a problem, the author of “The overpopulation myth” Fred Pearce and the author of “Overpopulation Isn’t The Problem: It’s Too Few Babies” Joel Kotkin disagree. This paper will examine the work of these four writers to analyze their perspective whether population growth has negative or positive consequences. Lack of food, reduction in living organisms, ecological and environmental problems as claimed by Tal are the outcomes of population surplus. He asserts that deterioration of China’s natural capital was part cause of China’s food crisis during 1958 and 1961 that resulted in more than twenty million people staving; as many died due to lack of food. China’s food crisis should teach the world a lesson states Tal that the outcome of taking no notice to the lack of natural resources and growing population is severe. He agrees that China’s one-child policy was not popular with the china’s people, however, it prevented many deaths caused by starvation. Tal goes on to explains that in the developing regions of the world one in eight people suffer from continues......

Most census data for various countries is at least two years old (and may be older). Population models have to account for growth since that data was collected. They also have to adjust for some errors in that data (miscounts, birth and death rates, migration, etc.). Given the variability of the base numbers and the differing estimates of errors, it is not unexpected that there are slightly different numbers. According to the US Census Bureau’s International Data Base (IDB) population clocks, at 17:05 GMT (EST+5) Feb 13, 2009, the world population was World 6,760,296,593. Thirteen minutes later, at 17:18 GMT (EST+5) Feb 13, 2009, the Census Bureau’s world population estimate was 6,760,298,598.

Human Population Growth

...Human Population Growth The world population growth is defined very simply as the number, or estimated number, of total births in a year, minus the number of total deaths. The difference between these two numbers tells us how many people are being added to the world population each year. To find this number, two types of population growth curves are proposed to explain increases: the exponential growth curve and the logistic growth curve. The exponential growth curve is when the population grows at a constant rate over time. It does not take into account competition, lack of resources, disease, etc. In other words, according to the exponential growth curve, the only thing that controls how fast or slow the population grows is the birth rate. On a more realistic level comes the logistic growth curve. This curve factors in the important reality that states, as the number of individual organisms in the population increases, resources need to increase as well. Also, human population growth HAS changed over time, but these changes were based on numerous factors that included disease, birth rate, economic conditions, etc. However, overall, the human population growth has slowed over the past century and projections indicate that the environment is near its carrying capacity. With this, food production must dramatically increase to keep up with the growing population or our population will be in trouble. While population growth, of any species, may be beneficial to...
