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.
IV. Short Answer Consider that Earth’s population is projected to rise to 10 billion by the year 2050. The current
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 United States’ population is growing at an alarming rate. Overpopulation is the condition where the population is rising rapidly and the resources cannot support it. The growth rate in the United States is approximately 2.2%. This means by 2050 the population could reach 438 million people (“World Bank Group”) Many
“Population will inevitably and completely outstrip whatever small increases in food supplies we make. The death rate will increase until at least 100-200 million people per year will be starving to death during the next ten years.”- Paul Ehrlich, Stanford University biologist
How many people can the planet support? The carrying capacity for any species is defined as the maximum number that can be sustained indefinitely, and in the case of humans is usually said to be about ten billion. As the global population grows from 7 billion to almost 9 billion by 2040, and the number of middle-class consumers increases by 3 billion over the next 20 years, the demand for resources will rise exponentially.
Ever since the beginning of recorded human history food production has always limited how much the human population can grow. The Malthusian Trap is a theory that as improvements are made to food production the total human population will increase proportionally to the increased food production. During the industrial revolution, many industrialized countries were able to break out of the Malthusian Trap and since then human population has grown exponentially. Now some of the major issues the human population is facing is disturbing the natural balance of the environment by having to turn more land into agriculture to feed a growing population. This loss of nature is causing a devastating amount of biodiversity loss throughout the planet. As new technologies emerge to try and solve these issues they must
Evolution; not only something A little known scientist with name of Charles Darwin created to get famous. From the evolution of humans to how humans evolved is a long process, millions of years to be more precise. Our evolving includes many things many people probably don't consider to be evolution of humans. For instance, how we learned to live in harsh or un-habitable environments and made them livable, to making tools with stone and sticks from there surroundings. During the Paleolithic Era Humans of that time gained food mainly by foraging which in other words is by collecting plant products, trapping and catching small animals even birds. Hunting larger prey was also a particular skill picked up later on though they learned These humans who developed and evolved during this time 2 million years ago were called homo erectus, or another name for upright human. They evolved in east Africa, and they also made tools that specialized in various tasks, those tools included handheld axes cleavers, even scrapers. The homo erectus' lived in larger groups so they could cooperate in hunting and gathering even food preparation. It was also found later by archeologist that the shape of the homo erectus Larynx suggest that people of this specific species were able to make wider range of sounds than were earlier hominids, so they relied more on vocal sounds than gestures to communicate ideas to one another. The Earlier humans most successful venture however had to how they migrated. Small groups at first started migrating North, leaving South Africa as temperatures rose. They made their way into Central Africa or the great plains then farther north into Northern Africa eventually moving north west into Asia as early as 1.8 million years ago. They even reached as far as
According to many scientists the world can only sustain about up to 2 billion people at a normal European living standard, and only about 6 billion with the global normal living standard and since there are 7 billion people in the Earth something
By the year 2050, nearly 80% of the earth’s population will reside in urban areas. The human population will increase by about 3 billion people by the year 2050. This means that world human population can reach the 10.6 billion people in less than 40 years which is an increase of almost 40% (Demeny and McNicoll, 2006). An estimated 109 hectares of new land, the area of the size of Brazil would be adequate for the purpose, will be needed to grow enough food to feed them, if traditional farming practices continue as they are practiced today (Monfreda et al, 2008). A growing population is not the only problem humanity has to face. Even today, approximately a billion people are chronically malnourished (Eigenbrod and Gruda, 2015), and, in addition,
According to Meder & Windelspecht (2014) the human population was approximately five billion people in the 1650’s, and by the 1850’s is doubled again. Now today we are estimated to have approximately seven billion people
Earth has been around for 4.5 billion years, progressing through several eras and phases. However, questions have begun to appear, with questions if the “Earth is Overpopulated?”, if “With the Earth’s Current Population, will it be capable of maintaining life at a sustainable level?” (Heaton), and if the Earth is at risk of running out of resources at the rate we’re consuming them? My answer to all these questions is no, that although the population is currently at 7 billion people, it is not at a point where it could be considered to be overpopulated, and it is not a point where the Earth cannot sustain humans with its resources.
As Paul Erlich puts it, “the balanced planet is limited and limited resources are on a direct collision course with population growth.” (Sabin) Research indicates that the earth could support 50 billion people but they would survive on substance living such as “bread”. But is that living? Resources are limited, especially if there are 50 billion people roaming the earth. All that the average family could live off of and afford would in fact be bread. Mintz’ shows in ‘Sweetness and Power’ how when a thing like sugar is not readily available, it becomes wildly expensive. The same thing would occur once again in the world;
As of 2016, the current global population is 7.3 billion people. At the current rate of growth, the global population is anticipated to be approximately 9.7 billion people by 2050. In addition, this population is anticipated to eat more of a middle class diet. Which means more meat, grains, and protein in a person’s daily diet.
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
