Human Race And Human Population

The first example of human manipulation of changes within the biosphere is through expansion. The rapid growth of the population has led to expansion in development; the need for more space is causing strain on other living organisms such as plants and animals. Human procurement of forest, grass, and wetlands has weighed on the animal population heavily. As a result of this domination, animals have lost areas they use to thrive in, causing migration and in more serious cases extinction. Animals are a prevalent source of protein for humans, and when a species is threatened by extinction, it not only disrupts the balance of the ecosystem, but it also disrupts the food chain. The more resources that are required to sustain human life, the bigger the need to migrate to surrounding areas in a short period of time (Haines).

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

Humanity is confronted by multiple environmental challenges which threaten to undermine the advances in health achieved over recent decades. The Rockefeller Foundation/Lancet Commission on Planetary Health showed how climate change, loss of biodiversity, land use change, ocean acidification and overfishing, nitrogen and phosphorus loading and environmental pollution more generally all have the potential to adversely affect health through a range of pathways1. A recent joint publication by WHO and Convention on Biological Diversity articulated the myriad connections between biodiversity and health and the threats to both posed by environmental change2. The dramatic changes in the global environment have led many scientists to conclude that we are living in a new geological epoch – the Anthropocene – in which the activities of one species – homo sapiens -have become the dominant driving force transforming the Earth’s natural systems3. These natural systems provide food, clean water and air and modulate the global temperature within limits in which humanity has been able to flourish for around 11,500 years during the preceding Holocene epoch.

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.

Humans played a major role in the extinction of large mammals because hunters possibly killed them off. They were also slaughtered with knives and stampeded over cliffs at that time at which their species became less and less. to extinction in a period already providing great stress due to the receding ice sheets as the last glacial maximum came to an end. Later, this would mean a lack of analogues

It is our actions that have directly, and indirectly, caused such environmental destruction; now it is us that must help save them. As John Sawhill said, "In the end, our society will be defined not by what we create, but what we refuse to destroy." We are their only hope; future generations of animals and mankind alike are depending on us.

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.

Nearly two million years ago, the first of our genus migrated through Africa under the species name of Homo erectus, a new organism that walked on two legs, with sloping foreheads and protruding jaws. Later evolving in the Homo sapiens, and then modern Homo sapiens sapiens, the human we know today quickly came into the world’s view as the top of the food chain and the predators of the period. Since their evolution in the Cenozoic era, the population of our species has grown quite literally exponentially, spreading into Europe, Asia, and the Americas. In the year 2017, our population has reached a whopping 7.5 billion - a sign of near reproductive and selective perfection. Impressive without a doubt, but the environmental impact of a predator

As we continue to grow and have a greater impact on the Earth’s systems, it is essential that we address our role and relationship with nature. The separation of humans from nature encourages environmentally irresponsible behavior because it allows us to take on the conqueror role, giving us the ability to manipulate the landscape with the duty to provide and proliferate. Throughout human history, we have made advancements in technology and agriculture, resulting in the imbalance and overuse of land. The ability of humans to manipulate the landscape and recognize the consequences of doing so makes us an invasive species. Our dependency on Earth’s resources and services put us at competition with the environment. In order to understand our role

We as humans were put on this earth to survive along with many other species. Some may argue that humans are the masters of the world and at the top of the food chain. The truth is that humans are soft, relatively weak, and have no sharp fangs or claws to protect themselves. Our most deadly weapon for defense is our brain. The world is a beautiful place with fragile checks and balances that make it all go around. Ecosystems thrive on the simplest organisms that are a food source for larger plants and animals. These fragile ecosystems have been a part of this world since the beginning. The human population is encroaching into the forests and other habitats where plants and animals live. The world is

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

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.

It is hard to tell what the future will look like in 35 years because there are many factors which play a role and some are difficult to predict. In order to project how U.S citizens will view the natural resources at that time, it is essential to understand what the future America will look like. I would base my answer on the projected circumstances I found in Joel E. Cohen’s paper called Human Population: The Next Half Century.

One specific way that humans have begun the process of world extinction is through their incessant meddling with the environment. Not only do people destroy the environment with our wreckage and pollution, but the human race has introduced species into other ecosystems, causing massive repercussions. Referred to as invasive species, their introduction into a

Despite what mankind would like to believe, humans are animals. As multi-celled organisms, we consume other organic matter, change the land for own uses as a beaver would build a dam, and as other mammals, we are all fed breast milk from our mothers when we were young. Yet there is this disconnection and alienation of the human race towards other species. Moreover, through fear of taking action, the convenience provided to us if we simply choose to ignore the environment, and the alienation of other species that are endangered by our actions, the hostile and uncaring attitude of humans towards nature is the core reason for many of the problems in our environment today.
