The Human Population Essay

The United States is the third most populated country in the world. This country holds about 4.5% of the world’s population. The U.S. population is currently estimated to have 308.7 million persons. This number is more than double of the population from 1950. Besides the fact of the population has doubled its size, the population has also become qualitatively different from the one from 1950. As noted by the Population Reference Bureau, “The U.S. is getting bigger, older, and more diverse.” The growth of the population is the result of the trends over time in the relationship of increased births, decreased deaths, and increased net immigration.

The human population is growing at an exponential rate. It is expected that the human population is going to increase to 9.6 billion by 2050, compared to 7.2 billion in 2013 (Porter). Because of the increasing human population, the rate of food production increases causing food waste produced to rise as well. Food consumption has decreased to less than a quarter of what was consumed in 1961 for people living in developing countries (Porter). These statistics are important to highlight because according to the United States Environmental Protection Agency, most landfills are made up of food waste which is causing the emissions of greenhouse gasses. The Environmental Protection Agency also states that cows produce one of the most dangerous greenhouse gas known as methane. Methane is 21 more times stronger than carbon dioxide. The reason why this needs consideration is because beef is the most consumed meat compared to other meats such as chicken, which has less greenhouse gas emissions. Countries with the most greenhouse gas emissions come from great financial economies in which citizens are privileged with what they eat. The increasing rate of releasing emissions by food waste can be dramatically slowed down by, using systems that convert food waste into a source of renewable energy, implementing policies that limit the amount of food waste in each country, and having governmental officials influence citizens to take into consideration the amount of food waste they produce.

Human population growth is becoming a huge issue in our world today. The population is increasing rapidly. The reason that it is becoming a concern is because it has affected the economic, environmental, and social aspects of our world. In the film Frontline: Heat, we can see how there might not be a future for our planet unless we are able to reduce the emissions and make our world a safe place. Not only for the present but also for future generations so that they are able to live long and healthy lives.

It is obvious to see in today’s society that the world has changed so much compared to the last decade and the many years before that. As time moves forward, the human population also grows along with it. And as the population steadily increases, the environment also deteriorates and becomes heavily impacted by the negative effects of overpopulation. Humans are the main cause behind every damage inflicted upon the world. With the rise of overpopulation, along with the countless number of humans already existing, the world will inevitably suffer severe damages. The world, without a doubt, would be so much better off with a limited number of humans as more would only bring it its demise faster.

The world is being over populated with humans not only in China but in the United States of America as well. The problem isn’t as obvious in the United States as in other countries, but I believe over-populated nations will soon become a problem everywhere in the world. Population is not a bad thing in all situations, but I think that our population growth problem is un-healthy and needs to slow down. I believe there are several ways to come about this problem as well. Population can be slowed down in many ways; it’s just how we choose to execute this problem.

Natural selection is the process whereby species that are better equipped for survival in their environment are able to prolong their bloodline by reproducing. Advancements in these species, evolution, can be seen as a result of natural selections force. Natural selection can be broken down into three concepts that require it to operate. The first is the constant struggle a species face for survival, which results in the continuation of the successful branches of the species, as the others become extinct. The second requirement is a varying population, these more successful branches only stem from mutated groups or individuals whose features become beneficial when faced with such struggles. The third concept is the presence of a mechanism that allows these mutations to be passed on to the next generation, thus evolving the species. All three of these conditions are interrelated, and must take place in order for natural selection to play its role in the evolutionary process.

This group of learners are well educated, although the predominant ethnic group is Hispanic and several learners do not speak English as their first language, all are fluent in English. The main issues that needs to be addressed from an instructional perspective are the varying range technology skills, the levels comfort with using technology and the time investment needed to complete an e-portfolio.

Within the early history of the human race, the earth was titanic and appeared boundless. Its resources seemed limitless. Then as the humans traveled away from home, the world got smaller and most of the world was recorded onto maps. Soon, the numbers of people were growing and the world and its natural resources looked as if it was shrinking. The overpopulation of an creature is dangerous to any environment, but with humans its deadly for the whole world.

Phosphate is an abiotic factor; therefore, it is a nonliving factor that affects living organism. In this experiment we prose to test the whether variation in environmental phosphate levels affects autotrophic organisms. We ran a lake and Chlamydomonas experiment in order to determine a solution for this question. In our lake experiment we took samples of water

A little over two hundred years ago a man by the name of Thomas Malthus wrote a document entitled “An Essay on the Principle of Population” which essentially stated that there is an imbalance between our ability to produce food and our ability to produce children. He said human beings are far better at making babies than they are at finding food for survival. His entire essay is based on these two assumptions. “ First, That food is necessary to the existence of man. And second, that the passion between the sexes is necessary and will remain nearly in its present state.” When taking into account what is said in this essay, it is obvious that his original analysis of population has been proven right. Today, in the twenty-first century,

Huntington, WV was named by the Center for Disease Control in 2010 as the least healthy city in the least healthy state of America in the most overweight nation in the developed world (Kilmer,et.al, 2008). Jamie Oliver, known as the Naked Chef, came to Huntington in the fall of 2010 to try to teach the school cooks how to prepare a healthier menu that the school children would eat. He was not met with open arms by the school cooks, the school system or children.

The population of Earth is estimated to be seven and a half billion, and the current growth rate per year is around eighty million. Since the world’s population is constantly growing at such a high rate, some people believe that it will lead to the downfall of the human race, while others think it is beneficial to continue on this path. The ongoing debate on world overpopulation allows many different people to offer their unique opinions, such as Erle C. Ellis, Joel Kotkin, Robert Walker, and Alon Tal. These writers offer perspectives that support and conflict the different aspects of the overpopulation issue. Both Ellis and Kotkin believe that overpopulation is not an issue, while Walker and Tal strongly believe that it is. Ellis

Overpopulation, which is the increase of human population on Earth, is one of the most harmful environmental problems going on in today's society. As the rate of deaths has decreased, the rate of births has gone up drastically. As the human population grows more in quantity in little time, there are numerous effects that it is having on production for human necessities that later harm the Earth. This is truly a problem as studies show that by 2025, almost half of the world will be facing problems with access to freshwater and 70% of all freshwater on Earth will be going towards human demand. Later on, this can evolve into many other problems that can lead to, as shown by studies, the next mass extinction. The origin of this problem all started out during the Industrial Revolution. As said by many, the Industrial Revolution changed the face of the planet. As more buildings and jobs were made, more people worked and got paid better and had the opportunity to have children because they were finally able to sustain them. Greater food production, new medicines, and better sanitation are some of the many factors that led to higher birth rates and lower death rates. Overpopulation on Earth is a problem to humans because of the negative effects on human necessities leading to climate change.
