Global Environmental Issues Of The World

The world population of 7.2 billion in mid-2013 is projected to increase by almost one billion people within the next twelve years. It is projected to reach 8.1 billion in 2025, and to further increase to 9.6 billion in 2050 and 10.9 billion by 2100. This assumes a decline of fertility for countries where large families are still prevalent as well as a slight increase of fertility in several countries with fewer than two children per woman on average.

Over population is an extremely serious problem facing the world today. According to an article from Newsweek in Oct. 2009 called “Where do babies come from?”, today’s world population has reached over 6.6 billion people. Also the article mentioned that in 2009 57.4% of all new born babies who were born this year came from Asia alone. This is an issue because over population can lead to hasty consumption of resources. China who has one of the largest population in the world with over 1.3 billion people, has taken a stance against over population.

The human population rate has changed throughout the ages. By looking at the table we were given the human population has increased heaps from 2000 years ago. If we look at our ancestors they lived with a small existence but this has changed as we have developed and there is more agriculture in this world. Population grew very slowly in the 1000 A.D. also decreased after the Black Death causing large numbers of people wiped out. Then in the 1800 A.D. the industrial revolution came, soon living standards were raised and there was food shortage with the population. In 1927 medicine was introduced this meant that there was increased life expectancy, so the human population grew more. There was more advantages from agriculture, medicine and sanitation

Thesis: The topic of human population growth is an important issue due to its impacts upon people in developing countries, economics, religion, food production, and the environment; without any limitations, population growth can lead to negative consequences, such as famine and environmental destruction, or even positive outcomes, such as potential economic growth.

There are more than seven billion people on Earth now, and about one in eight of us don’t have enough food to eat. So, with a projected nine billion people by the year 2050, how many people can the Earth support while maintaining a healthy population? Population changes are due to the relationship between births and deaths. If the number of births equals the number of deaths then the world’s population will remain the same, but if births exceed deaths, population growth will occur. Early in history, population was slowly growing because of high death rates related to wars, famines, and poor medical services. With advances in

As the human race continues to grow older the population starts to grow. Population growth is a change in the size of a population over time, depending on the balance of births and deaths over a period of time. For the world, population grows when the amount of births exceeds the amount of deaths. As shown in figure 1, the world’s population grew very slowly until about 1750 that is when the population growth started to increase rapidly. Figure 2 shows the growth of the global population from 1950 onwards, it also shows the projected population growth up to 2050. The global population is estimated to rise to approximately 9 billion people by 2050.

The article by Dennis Dimick brings up some very good points about the increasing population. He states that with our current population of 7 billion people, we currently do not have enough food to eat. With the population increasing day-by-day, we will face more shortage in the future. He also brings up the issue of natural resources. We are currently using so much natural resources that we will run out very soon. The use of natural resources tend to increase with increase in social standing (wealth).

The Global human population increases growth amounts to around 75 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7 billion in 2012. It is expected to keep growing, and estimates have put the total population at 8.4 billion by mid-2030, and 9.6 billion by mid-2050. Many nations with rapid population growth have low standards of living, whereas many nations with low rates of population growth have high standards of living.

Another very crucial environmental issue, besides global warming, involves the finite nature of natural re, which are being depleted faster than their replenishment rates. The development model of the 20th century, which promoted the continuous consumption of products, has resulted in the reduction of agriculture land, food, water re as also fossil fuels. If humanity continues to consume fossil fuels at the same rate as today, oil re will run out by 2030, gas by 2040 and coal by 2200. By 2025, the number of people suffering due to water stress will rise to approximately 3.5 billion and almost half the world’s population is expected to experience high water stress by

While it may be observed that the exponential rate of growth is slowing, the world population is still growing rapidly. Perhaps the biggest concern is not the actual population increase but the distribution of the growth (Wilson, Population).

In the world today we have became to known of the upcoming problem;its not only been a problem in the U.S but other counties as well. Today’s population consist of 7,362,302,944 people world wide.Although, growing in population is consistently is a bad thing but it can be a good thing.

The expansion and development in all of the earth’s climate zones and habitats, as well as modern agriculture’s ability to grow more food for each unit of farmed land, play an important role in the population growth. Socioeconomic factors such as, healthcare, culture, family structure, marriage and social status also influences population growth, are contributors to population size increases through birth rate, as well as, decreases through the death rate. This imbalance of population equilibrium is a result of improved sanitation and health care, and the development of antibiotics and vaccines for the control of infectious diseases ultimately resulting in population death rates dropping.

Our planet’s carrying capacity for prehistoric Homo sapiens was probably near 100 million. However, without their Paleolithic ways of life and high-tech technologies, the population would be much less - possibly a couple tens of millions. The advance of agriculture allowed even larger population growth to occur, demanding for even greater land-use practices to earn more nourishment from land. At some point, their farming systems could have supported a couple billion people. The world population is currently almost at 7.5 billion, but with our technologies, the Food and Agriculture Organization of the U.S. has estimated that the people born after we reach nine billion could be sustained if necessary expenses in food policies and anti-poverty

It is predicted by the year 2050 the world's population will have increased to over 9 billion people. (International...) If this prediction comes true the world will become overpopulated and cause problems like famine, the world already struggles with feeding the amount of people alive today. A second problem is housing, in underdeveloped countries there is already a struggle with giving people places to live, so companies clear land to build houses but that leads to habitat loss and animal loss. The third reason is disease, if a disease was started and spread when the world was overpopulated the disease could eliminate half of the human population.

One of the problems facing our world is population. It began about ten thousand years ago when the humans settled and began farming. The farming provides more food for the people thus making the population grow. Now we are about 6 billion in population and in a few years we will be around 10 to 11 billion. Therefore, our population will
