It took the beginning of time until 1804 to reach a world population of one billion people. Population statistics show that there were 1.6 billion people in 1900 and this figure reached 6 billion before the end of the 20th century. Over the past several decades, the world 's population has been growing exponentially. According to the population statistics, this figure is going to ascend to more than 9 billion people by the end of 2050. Recent studies shows that the growth rate of population has somewhat steadied from the prior projections due to various things such as increased education, along with higher death rates due to the spread of numerous diseases. Despite these recent projections, the overall trend of rapid population growth remains, creating numerous challenges for engineers. The main concern for engineers is that this rapid increase in population, along with fast paced industrial growth, places a tremendous strain on land, energy, and water resources that are essential for human survival. These challenges for engineers will required them to use their talents in effort to improve these situations.
One of the biggest concerns for engineers with the growing population is the tremendous strain on land. In many areas of the world, the land suited for food production is dwindling. This creates a major problem since there will be a high demand of food production with the growing population. Suitable land and mass food production are both necessary for human survival.
Over the past years, there has been an exceptionally large national increase which has caused several population issues. These issues include: homelessness, deforestation and more fields being used to make space for shops and houses disrupting the biodiversity growth. Problems like this are caused when there is an abnormal increase in the birth rate where more babies are born; this is also known as a ‘baby boom’. This can occur when nations have more children as a whole and events like this normally takes place after an achievement – an example being when we won the World War Two. The country was relieved that the fighting was over so their instantly celebrated which is why more children were born. In the last 50 years alone, the population has doubled showing just how fast the population is actually growing and even though it may seem fortunate that there are less recorded deaths, this makes the Economical
In October 2011, the United Nations announced that the world's population had reached 7 billion. By the year 2050, the UN predicts that the population will increase to about 9.6 billion. Our rapidly growing population has many concerned about whether or not the Earth can sustain more than 7 billion people. Many people are worried about what the human carrying capacity is and what will happen if we exceed that. Others believe that we will continue to be able to support population growth through innovations in technology. Erle C. Ellis, a professor of geography and environmental studies, holds this belief and presents it in his article "Overpopulation Is Not the Problem".
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.
The indefinite growth of the human population, has monumental impacts on the natural environment, not only in the UK, but around the globe. Architecturally, the entire process of designing and constructing a building, both domestic and not, can lead to the rapid exhaustion of natural resources across the planet. Building with environmental design strategies in mind not only combats the impact we as humans have on the natural environment, but also has considerable economic benefits, due to lower running costs of buildings and advanced occupant productivity. There are also many social benefits, such as improved air quality which resultantly leads too enhanced health of a buildings occupants.
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.
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.
population increase, now approximately 1.7 percent a year will decline to a little less than 1 percent sometime between the years 2020-2025” (Ehrlich). The more people added on to this earth the more resources we will have to use
The lab help us to undestand all the factors that has a impact in the population and the measures that can be taken to find an equilibrium of the population growth. The earth has a carrying capacity and this lab is useful to analayze and be aware about the effects in the environment caused by the population growth.
It was recorded in the year 2011 that the worlds population reached approximately 7 Billion. However, when studying the current birth rate, experts have predicted that by the year 2050 the worlds population will reach more than 9 billion. Leaving agriculturalist and scientist concern on how to help feed the over 9 billion that would soon populate the earth. This leaves many factors to blame for the contribution to population growth. The first factor would have to be the life expectancy rate of humans nowadays. Medical advantages and technology have made it possible for humans to live a longer life. The next factor, and most important is agriculture. In order to thrive in future generations, we must find a way to provide food to consumers without harming their health or the environment. That is why within the next 34 years we must produce twice as much food that we currently receiving in order to provide for our populations growth.

Population growth simply means an increase in the number of people that inhabit a county or a city. The current human population growth is something extraordinary in the world’s history. Human population growth is one of the biggest issue in our world today. World population increase by over 228,000 every 24 hours (Population Reference Bureau). The reason that it is becoming such a critical issue is because it has effects on the economic, environmental, and social aspects of our world. Experts believe if we continue to grow at this pace, by 2050 Earth will need 50 percent more energy to sustain humanity.
As the century began, natural resources are under increasing pressure, threatening public health and development. Water shortages, soil exhaustion, loss of forests, air and water pollution, and degradation of coastlines afflict many areas. As the world's population grows, improving living standards without destroying the environment is a global challenge.
The topic of expanding population is one both of wonder and catastrophe, as civilizations have risen and fallen throughout time. Collapse (Diamond) touches on this concept of population growth (or change) often, especially because a civilization is, after all, nothing without its population. Using Collapse, we can quickly start to analyze what a growing population entails.
POPULATION: It is predicted that in about 1000 B.C. the population was about 265 million people. The world population continues to grow greatly. Between 1850 and 1950, the overall population doubled from 1.265 to 2.516 billion people. Between 1000 B.C. and 1850 the population grew on average a little less than 1.5 million people per year.(Our World In Data). As of 2015 the human population is over 7.3 billion people. According to the United Nations, the human population will be over 9 billion by 2050. By 2100 they predict that the population will be between 9.6 and 12.3 billion. In terms of population history can be split into three different periods. The first period was a very long period of time where the rate of
In the bible when god created man he had stated “Be fruitful and multiply, and fill the earth”, (Genesis 1:28). It would seem that mankind has responded to our fathers request quite well. But is seven billion that big of a number? “If everyone in the world stood shoulder to shoulder, we could all fit within the city limits of Los Angeles”, (cbsnews.com, n.d.), so then what is the big deal about the growing population? Well, humans must eat, use energy, consume water and also humans will need more space to live as the population grows. This means that there will need to be a lot more food to be grown and produced, a lot more raw materials used to make energy and a lot more land to build infrastructure for humans to live and more water. Which is all fine and dandy until one is reminded that land, and raw materials are limited and the rate of food production is linear and land availability is also a factor for production. If that is not bad enough, according to prb.org (2011), “There are now seven billion people on earth, and projections show that we will top eight billion in just twelve years from now.” It is quite obvious that policies need to be implemented which limit or control the population growth rate or we might use up the finite resources which we have on earth.
