Recommended: Essays on human evolution
The existence of the earth has been here billions of years ago. All of the natural resources and the hidden secrets remain unknown until a biotic being discovers them. Time passes, and Homo sapiens, casually known as humans, have inhabited the earth. During the billions of years, the evolution of humanity is increasing, which is evident in the several innovations that exist to this day. Closing in the present age, the human population expands exponentially and more people are using the natural resources that come from the earth. To this day, over 7 billion people now live on the earth after billions of years ago where no beings have existed back then. New discoveries are uncovered and people gain new knowledge on existing and new outcomes. …show more content…
As humans, people have their own free will and mind to make their own decisions. What several people are ignorant in is the fact that the usage of an abundant of necessities is depleting at quicker speeds as the population grows over the years. Due to this fact, the earth and the people living on it has been and will be suffering from the widespread consumption of the natural resources that are crucial for everyday life. As the population increases, the consumption does not decrease and people’s unawareness to the world is destroying the planet they call home. Furthermore, the future becomes grim as society continues to act without changing their ways and living up their name as a “super predator” for themselves. Without the balance necessary for the planet, this is one punishment that humans are now facing in the present and future without worrying that the earth deserves fair treatment. As the population increases, humans are facing an exponential growth relating to the consumption rate as the earth deteriorates from the unsustainable lifestyle of
Society portrays the Earth as a resource, a place that provides an abundance of tools that are beneficial to one’s way of living. As time continues on, humanity’s definition of sustainability with the ecosystem becomes minor, meaning that it is not essential to their own lives. Thus, leading to the environment becoming polluted and affecting the human population. These ideas are demonstrated through these four sources: “Despair Not” by Sandra Steingraber, which provides the author’s perspective on the environmental crisis in terms of climate change.
As small mobile groups of hunter-gatherers adopted a sedentary lifestyle, they mastered both agriculture and animal domestication. These small settled groups quickly evolved into cities and towns that encompassed the entire globe. Today the estimated population of the world is over 6.2 million people.1 As the population has grown, it has had several deleterious effects on the Earth. These include climate changes, the spread of diseases, declining food production, deforestation, and environment pollution (particularly air pollution). As people have become more conscious of these harmful effects, they have begun to devise strategies to combat this problem. Among the suggested responses include a switch to renewable energy, a call for zero population growth, and adopting sustainable agricultural practices.
As time passes, our population continues to increase and multiply; yet, on the other hand, our planet’s resources continue to decrease and deplete. As our population flourishes, human beings also increase their demands and clamor for the Earth’s natural products, yet are unable to sacrifice their surplus of the said resources. Garret Hardin’s work highlighted the reality that humans fail to remember that the Earth is finite and its resources are limited. Hardin’s article revealed that people are unable to fathom that we indeed have a moral obligation to our community and our natural habitat — that we are not our planet’s conquerors but its protectors. We fail to acknowledge and accept that we only have one Earth and that we must protect and treasure it at all costs. Despite all our attempts at annihilating the planet, the Earth will still be unrelenting — it will still continue to be present and powerful. Human beings must recognize that we need this planet more than it needs us and if we persist on being egocentric and covetous, in the end it is us who will
Planit Earth when seen from the vast vacuum of outer space stands as a testament to the remarkable phenomenon called life. When viewed from a far Earth appears resolute like a resting marble. However, in reality, this marble of life is under constant change. This constant change is relatively normal and promotes an equal balance in the ecosystem over time. However, over the past hundred years, this balance has shifted. Human beings are now affecting the environment in major ways. In the past humans have lived their lives in ignorance, unaware of their impact on the earth 's environment. The ignorance of past generations is excusable to a point. However, the idiocracy that exists in society today is unforgivable. For decades, humans have studied
“The scientific study of how humans developed did not begin until the 1800s in Europe. Until that time, people relied on religious explanations of how humans came into existence. Starting in the 1500s a scientific revolution began to sweep Europe. Thinkers started using scientific methods and experiments to try to better understand the world and the creatures living in it. Eventually these methods were turned to the question of human origins” (The Nature Of Human Origins, 1). Earth made it possible for species to change over time because Ancient Earth provides ability to plenty of time.The Homo Sapien a is very complex creature. The species started off very simple by living in caves and surviving with little food and then later evolved into a species that were able to do many more complex things. The first species was Sahelanthropus tchadensis They were one of the most simple humans in that time period and on. They had very small skulls compared to Homo Sapiens today and their motor skills were just the same. We have evolved and changed for the better both mentally and physically. The Evolution of Homo Sapiens started off simple, such as the Neanderthals, and now we are the most advanced species to ever walk the planet so far.
Author Yuval Noah Harari has a unique way of reviewing the past fourteen billion years in his monograph Sapiens: A Brief History of Humankind. His intention for writing this book is mainly to bring up the conversation of the human condition and how it has affected the course of history. In this case, the human condition coincides with the inevitable by-products of human existence. These include life, death, and all the emotional experiences in between. Harari is trying to determine how and why the events that have occurred throughout the lives of Homo Sapiens have molded our social structures, the natural environment we inhabit, and our values and beliefs into what they are today.
It is argued that the growth periods of childhood and adolescence is unique to the human species and is not observed in other living mammals. During this period human experience observable growth spurts in both height and weight at much higher levels than other mammals and primates. This is what set humans apart as the physical and behavioural characteristics of the adolescent stage are observed in other mammals. The evidence stems from the peak velocities for growth, often in response to hormone levels characteristically lower than in primates (Bogin. B, 1999). Within these values there is sexual dimorphism in the levels of these growth spurts. The childhood life stage is the precursor to the juvenile stage and the adolescent stage occurs post puberty (Bogin. B, 1997).
Evolution is the complexity of processes by which living organisms established on earth and have been expanded and modified through theorized changes in form and function. Human evolution is the biological and cultural development of the species Homo sapiens sapiens, or human beings. Humans evolved from apes because of their similarities. This can be shown in the evidence that humans had a decrease in the size of the face and teeth that evolved. Early humans are classified in ten different types of families.
From preschool into early elementary school, children have begun to develop their gross motor skills. They have developed a “mature pattern of walking” and are ready to test their physical abilities to the limits. Also fine motor skills have begun to develop, however more slowly. Along with motor skills children are developing their visual, tactile, and kinesthetic senses. A child’s sensory skills are helpful in learning language.
Every day when looking out a window, people see a beautiful earth. The earth is intriguing, but hinges on a delicate balance. Many natural resources keep the grass green and the sky blue. Man has made quite an impression on our world, and has transformed the earth's resources into tools to make life easy. However, mans' manipulation on earth has become detrimental to the health of our planet and the safety of mankind. Through the use and production of resources such as oil and energy, man is gradually poisoning the earth. Pollution has become such a dilemma in society; there is no real control or a feasible solution to society's recklessness. Without complete change, our system will collapse. The earth will eventually retaliate with disaster, or corporate control of our economy will cause hysteria and depression. Evaluation of the consequences and repercussion of worldwide pollution, may give people a better idea of what the future holds.
Human species or in scientific terms know as, Homo Sapiens has evolved drastically in the last couple of billion years. Human evolution all started from our great ancestors, the chimpanzees. Human evolution started all in the continent of Africa. Due to global changes, evolution changed over time. Thus leading to the evolution of mankind. But man didn't just evolve from chimpanzees. There were a lot of scientific processes and different events that led up to final evolution of mankind. But what does it mean humans evolved from chimpanzees? Why is the human evolution such a small speck in the evolution graph of the evolution of the whole earth? These questions that have been asked frequently by curious people has led scientists to dig deeper into this topic. The answers to how humans evolved has led to some great discoveries.
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.
Many people assume that the environment is not in danger. They believe that as technology advances, we do not need to worry about renewing natural resources, recycling, and finding new ways to produce energy. They state that one person in the world does not make a large difference. In reality, each individual's contribution greatly affects our environment. Our natural resources are slowly disappearing, and we must work together to save them and the Earth from ruin.
Though several people see large rapidly growing populations in developing regions as the primary culprit in environmental decline, we need to focus on the costly environmental outcomes of overconsumption among the gradually increasing populations of the developed nations. These differing emphases naturally point to fundamentally different solutions: slow population increase in less-developed nations or change destructive consumption and production patterns in the more-developed nations. This debate, however, assumes a one-step answer to the complex problems created by population pressures on the environment. Both population size and consumption ...
Overpopulation can be seen as one of the key factors responsible for the state of our rapidly decaying earth. Developments in medicine, agriculture and technology have allowed for the human race to take over all other species and be excluded from the natural food chain. Humans, particularly westerners, lead lives of extreme consumption that take huge tolls not only on the earth but also on certain groups within society. A great division has developed between the western world and the third world.
