Earth is home to millions of species. Just one dominates it. Us. Our cleverness, our inventiveness, and our activities have modified almost every part of our planet. In fact, we are having a profound impact on it. Indeed, our cleverness, our inventiveness, and our activities are now the drivers of every global problem we face. And every one of these problems is accelerating as we continue to grow towards a global population of 10 billion. In fact, I believe we can rightly call the situation we 're in right now an emergency, an unprecedented planetary emergency. We humans emerged as a species about 200,000 years ago. In geological time, that is incredibly recent. Just 10,000 years ago, there were one million of us. By 1800, just over 200 years ago, there were 1 billion of us. By 1960, 50 years ago, there were 3 billion of us. There are now over 7 billion of us. By 2050, your children, or your children 's children, will be living on a planet with at least 9 billion other people. Sometime towards the end of this century, there will be at least 10 billion of us. Possibly more. We got to where we are now through a number of civilizations and society-shaping "events", most notably the agricultural revolution, the scientific revolution, and the industrial revolution. By 1980, there were 4 billion of us on the planet. Just 10 years later, in 1990, there were 5 billion of us. By this point, initial signs of the consequences of our growth were starting to show. Not the least of these
2,000 years ago the world, in terms of population, was only the size of the United States of America, 300 million people. Today, the world’s population is at seven billion and counting. If the population rose at a steady rate from year 0, we would’ve reached 1 billion people by about 210 A.D. This, however, was not the case. We reached 1 billion people in 1800 A.D, which means that there had to be very odd growth periods for the population as a whole REWORD ME. From 0 to 1000 A.D. the population only rose about 10 million people, “and well into the second millennium, [the population] grew less than 0.1 percent each year” . However, from the year 1800, with 1 billion people worldwide, to 1930, the world gained another billion people. We then reached three billion people in 1960, five billion in 1987, and 7 billion in 2013. One can clearly see that once we entered the 19th century, the world’s population started growing like a 14 year old boy going through puberty; rapidly, and without any warning. One thing that can explain this growth is called the Demographic Transition.The Demographic Transition is a theory that explains the growth.
As of right now,there is much wrong with the world. Wars are being fought, crime, rape and racism are still undoubtedly alive. This upsets countless people, movements have been made while others brawled back. With much crisis going on, numerous people seem to forget where it is all happening; Earth, mother of all things. Species whom have been around longer than humans are impelling extinction, the polar ice caps are melting, and landfills are overflowing. It is a terrifying thought to consider that the ones at fault for all of this is mankind. Each individual has a role in addressing environmental sustainability, and most are not doing their part.
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
The world is in a constant state of change, today’s decisions will affect the future of all species large and small, defining the ways in which society will continue to live. The essay “No New Worlds” written by Dr. Adrian Forsyth explores ideas associated with ever changing populations and states of the world. The essay describes the existence of humankind by their impacts on the surrounding environments. The reader is then introduced to the implications our world faces if these problems are not solved and additionally steps to solving these issues. Thus, both men and women need to take action to help or pay the consequences and protect the only world we have, planet Earth.
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.
Throughout the last few hundred years, humans have built a foundation. Compared to all of the other animal species on Earth, humans are the most intelligent. We have built houses everywhere, developed a system to sustain ourselves, and now inhabit almost every piece of land on earth. Humans are smart, strong, and know how to fend for themselves. But, humans have a tendency to take it too far, and we have already done so. There have been numerous advancements over the past few hundred years which could ultimately lead to the downfall of the human race. The main issue is overpopulation due to the advancements in technology and general knowledge. The statistics from an article by Kenneth Smail show that “In the year 1900, there were almost 2 billion humans living on Earth. Throughout the 1960’s, the baby boom, there were 3 billion humans on Earth. Today in 2016, there are just over 7 billion humans living on Earth.” Currently, we have taken up just over half of all available land on this planet, and with increased amounts of people having kids, our population will only increase. Overpopulation is becoming a serious problem all around the world, especially in countries such as China and India. There are many global problems associated with overpopulation that are becoming more and more prevalent, which will all have dangerous effects on the foundation that humans have
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.
Main Point 1: Us humans have overpopulated the earth and will continue to grow if actions aren’t took. We had a population approximate to 7.4 billion people living on earth in 2016. It takes about 40 years to increase the population by 3 billion. Earth can only hold 10 billion people max. Therefore, we will overpopulate the earth around 2040. We need to conquer another planet however, not all planets have the basic elements to sustain life.
The human population has been growing rapidly for centuries. What is happening and, most important, what will happen to all of us and our planet if this continues? One of the most important properties of living things is that their abundances change over time and space. This is as true for our own species as it is for all others, including those that directly or indirectly affect our lives. for example, when providing our food, or materials for our shelter, or causing diseases and other problems. It is safe to say that human populations, like that of the United States, grow at an exponential rate, which means that the annual growth rate is a constant percentage of the population. The danger that the human population poses to the environment
The human population is growing rapidly, and Earth doesn't have enough space for it. In 1967, Earth had a population of 3 billion, and only about 50 years later, that number had doubled into 7 billion. There are many reasons why our population is increasing so fast, in so little time, but I'll only go over two. The first, and foremost the most recognised reason, is the birth to death rate ratio. Every minute there is almost twice as many births then there are deaths; 200 births to 100 deaths. There is an estimated 350,000 born every day with only 150,000 deaths, making there 4 births every second and 2 deaths every second. Overwhelming right? Well the second reason which goes hand in hand with the birth to death rate, is, over the last few hundred years, we have become more intelligent, and more self aware. Our knowledge on medicine has grown like no other, and our life expectancy has grown with it. With many more factors modifying our population rate, these two show it best. We are living longer and having more babies, but soon we’ll need to stop.
According to the lecture, “If the birth rate is higher than the death rate, then population growth will be exponential.” What sets us apart from history is the fact that our death rate has greatly decreased due to our ability to fight leading causes of death. In historic times, the average projected age of survival was far lower than it is now due to the lack of knowledge on how to deal with and prevent different diseases. As time passed, humans began to learn more about medicine and treating sicknesses, but this was a slow and steady process. Plagues like the Black Plague during the 1300s killed off millions of people in Eurasia, preventing the population from growing exponentially. Couple with war and crime that was at its peak during the 1940s, the population did not have room to grow up. But as time continued, the rate of war and crime decreased, leading to one less reason of death to worry about. Famine was also a huge cause of death during 1870 but begins to decrease in 2010. The combination of the decrease in causes of death that stems from the better technology to deal with diseases, less wide-scale wars, less famine, and the continuous birth of new live caused the population to seem rapidly grow from around the 1950s onwards (this makes sense as it was right around the end of WWII, the last major war to affect the entire world). The migration of people and intermixing
The future of our planet has been a great concern for the global community for many years. In their article ‘Can a Collapse of Global Civilisation be Avoided?’ Paul and Anne Ehrlich explore the current ecological and socio-cultural trends that they believe, if left untreated, will lead to the inevitable collapse. Unlike past civilizations, the modern global community has the knowledge, skills and technologies to solve the several pressing issues Ehrlich presents in this article. So what are those issues?
Between 1400 and 1700, the global residents rose slightly from 300 million to about 1,2 billion people but then this figure dropped marginally to just under 1 billion humans. After a decline of 300 million people, the number of this grew sharply by nearly 5 billion, to exactly 6 billion people worldwide at the end of the examined period.
By A.D. 1 global human population increased to about 300 million and grew continually at a moderate rate. The 18th Century Industrial Revolution saw the rise of living standards and diminished famines and epidemics in some regions. Population growth then accelerated. The population jumped to about 760 million in the mid 18th Century and crossed 1 billion towards the beginning of 19th Century.
