Impact Of Population Growth On Population

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

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 current global population of 7.6 billion people is expected to reach 11.2 billion in 2100 (UN DESA), and as the Earth’s population continues to grow exponentially, the topic of environmental sustainability is being debated with increased urgency. In the past few years, many large-scale environmental issues have emerged due to human activities: climate change, air and water pollution, rising sea levels, habitat loss, species extinction, and worsening natural disasters are all becoming more and more prevalent. But perhaps our most immediate concern should be whether or not we will be able to continue feeding this ever-increasing population.

Booming human population growth over the last two centuries has put, and continues to put, many of these life-sustaining systems out of balance and in serious jeopardy, endangering many of the plant and animal species that human beings directly and indirectly depend upon for long-term survival. Bigger human populations naturally mean increases in human activities worldwide, leading to changes in landscapes, oceans, atmospheres, and the path of human history. Some of these changes

Most ecologists consider human population growth to be one of the most pressing problems contributing to environmental degradation. Human population growth works in conjunction

The world’s population is anticipated to reach nine billion by 2050, having almost ninety percent of that growth occurring in the developing world. On top of that, the world’s population will continue to develop toward urban areas having approximately 70% living in urban populations by 2050 as compared to around fifty percent today. The world has faced an unprecedented rise in population during the past century having dramatic shifts in the production and consumption of food and for the most part has accommodated this population explosion, but with the changes in the consumption of meats in the world, the strain on resources will become more severe. In 1965, the per capita consumption of meat in developing countries was around ten

{draw:rect} Population control has been a topic of conversation for the past 50 years. During that time many attempts to lower the global population have been attempted. Over-population is taking a toll on the environment and human health. What can we do to help solve the population problem? There is no quick fix. Right now we have a bigger problem to deal with: starvation due to over-population. According to Darwin, all organisms produce more offspring than will survive to maturity (Nadakavukaren, 2006). Biotic potential is the maximum growth rate that a population could achieve provided there are no factors to limit growth such as food shortages, overcrowding, disease, predation, and toxic waste accumulation (Nadakavukaren, 2006).

We, as humans, are in a very dire situation. Sometime near the year 1800, the population of the Earth had reached one billion residents (Roster & Ortiz-Ospina, 2013). In the last two hundred years, however, the population of Earth has exploded to almost eight billion. The rate of increase is like nothing we have ever seen before in the history of the planet. One billion new earthlings were added in the last fourteen years (Roster, 2017). Many factors are at play which have directly impacted this exponential population growth. With limited resources and land available, we as humans are reaching a defining moment (Dimick, 2014). Protecting necessary resources such as clean air, fresh water, and a sufficient food supply, while simultaneously supporting steady population growth will be a huge challenge in our future. The population growth rate of humans on this planet will become a huge factor in the survivability of our species. Taking responsibility and changing our behavior may be the only way to save ourselves.

According to the UN about 2.7 billion people across the globe will face water shortages by 2050 if changes aren’t put into place. That’s nearly ⅓ of the world’s population and on top of that 2.5 billion will find it hard to find enough freshwater to meet their daily needs.

Throughout time the human species have relied upon and utilized the Earth’s natural resources in order to survive everyday life. As years pass by human population is growing at an alarming rate and resources, in time, can and will become limited if proper steps aren’t taken now. During the 1970’s three men, John Holdren, Bary Commoner, and Paul Ehrlich developed a formula which measures the human impact on the environment. This formula I=PxAxT, refers to human being’s impact equals the product of its population multiplied by affluence and technology. “The world population is at 6.8 billion. That figure will rise to 9.2 billion by 2050. Meanwhile, climate change is speeding up alarmingly. So, are there too many of us? And if so, how long before our planet becomes unfit for purpose?” (Lord 24-26). In this essay, I will attempt to explain my understanding of the IPAT model and evaluate its current data trends within the human population.

Overpopulation has been a growing problem over the past 60 years with an additional gain of 4.5 billion people since the 1950s. In 1750 AD the human population was at 800 million and had reach only 2 billion by 1927 (Schriever), however, in just merely 90 years, the population dramatically skyrocketed to 7.6 billion. In 1980, China tried to manage the overpopulation problem by releasing the one child policy, however, when it ended in 2016, their population increased a whole 0.46% (Verrill), that’s nearly 350 million people. There is no denying that humans are now the most dominant species to inhabit planet Earth. In fact, humankind is using natural resources at a rate 44% faster than what the world can regenerate, putting a strain on the world’s life-sustaining resources. The growing worldwide population is the cause of most environmental problems.

Two hundred years ago less than one billion humans roamed the earth. Today the current world population stands at 7.3 billion and is expected to reach 8.5 billion by 2030 (source UN) this is due to the decline in death rates and increase in birth rates. The population has seen fluctuations, and changes over the centuries with astonishing peaks during the 20th century. In order to understand these changes, we will need study the growth, the explosions and drops in the world’s population. In this unit, we will therefore be analysing the causes of population change as well as the potential consequences.

1) What is exponential population growth? I found this a bit confusing the more I researched it. My understanding of Exponential is when something grows at a rate that doubles – 2, 4, 8, 16, 32, etc. However, it has a little different context when applied to population. The explanation I found that seems the clearest is as a population's per capita (individual) growth rate stays the same regardless of population size, the population grows faster and faster as it gets larger (Khan, 2017).

Despite a continuing slowdown in the rate of population growth, it is “almost inevitable” that the number of people on the planet will rise from 7.3 billion today to 9.7 billion in 2050, according to the latest UN projections.

Have you ever thought what will happen with us in our nearest future? Is there will be better life than today? When I first saw headlines such as “Better life is coming” or “Future without problems, it’s true”, I was tempted to answer, “Yes”. However, these facts aren’t so widely reported in the newspaper and television. But the nearest future, in fact, is not as fluffy as it seems to be. Moreover, there will more global problems than we have. The population of the world keeps growing. Every 15 seconds, approximately 100 babies are born. Experts predict that by the end of the next century, the population could reach 10 billion people. One of the major problems of population growth is
