Human Impact On The Environment

We are only a brief second in the long history of the universe; many things have preceded us to make us the most complex creatures that ever walked the Earth. We are a “new level of complexity” which makes us different from all other creatures that have come before us. Our species has only been around for 250,000 years, a short time compared to the formation of the Earth at 4.5 billion years ago and the creation of the Universe at 13.7 billion years ago, but the time we have had on this Earth has greatly affected the outcome of history. In an attempt to provide an overview of human history in his book This Fleeting World, David Christian introduces it in the context of the history of the universe and then systematically breaks it down

The biosphere consists of a compound infusion of gases; the main components are oxygen, nitrogen, and carbon dioxide. The concentration of these gases have been changing for many years. For the most part, this is influenced by human activity. In a persistent effort to improve the quality and longevity of life, humans (particularly in industrialized societies) have tendencies to negatively impact the environment, and at the same time, we strive to replenish what we have nearly depleted to balance the scale.

Describe the major developments of early human and social evolution. Throughout, discuss tool manufacturing, language development, agriculture, social behavior, and population growth.

Human existence has lasted over several million years and in that time there has been countless advances in the way we live. Human history has had many diverse periods of time, one being the Stone Age. During the Stone Age there were two major subdivisions, the Paleolithic and Neolithic periods. The Paleolithic, which lasted until about 10,000 years ago, had a significant separating factor from the Neolithic, ending in 2000 B.C.E. This factor was the way in which the people in these periods acquired food. The Paleolithic people hunted and gathered their food while the Neolithic people produced their own food by agriculture. These two different styles of obtaining food greatly affected the lifestyles of each period’s people. The

Approximately 2.5 million years ago humans lived as hunter-gatherers that would move in bands, later on, they would turn into the great civilization of the ancient world due to better technique and a more organized society. Starting from the neolithic age which consists of hunter-gatherers. There were basically early modern humans. Hunter-gatherers had populated a lot of the earth by 30,000 years ago, continued the hunter and gathering way of life. They would feed off of wild plants and animals and move from one location to another. They would also use the fur of their killings as clothes. In a hunting and gatherings economy, they would move from one location to another to secure their food supply. Hunter-gatherers were very self-sufficient.

1. Humans first appeared on Earth during the Paleolithic Era. The evidence of burial grounds, stone tools, and other items shows a general migration path of humans out of Africa, and support the theory that these groups were nomadic hunters and foragers. Early humans were mobile and could adapt to different geographical settings from savannah to Ice Age tundra. Anthropologists infer that these bands were relatively egalitarian.

In the beginning of the Paleolithic Era, bands of humans progressively migrated from East Africa to Eurasia, Australia, and then to the Americas while adapting to their new regions. During the Paleolithic era, hominids used crude tools like clubs and choppers to crack open bones, simple axes, and scrapers to prepare animal hides. As the years went on the Neanderthal, Cro-Magnon, and Homo sapiens amended these tools and created new ones. They made these tools so that they can provide shelter, protection, defense from other predators, food, and also clothing. As the Paleolithic era was ending, the hominids were building much more innovative wood and stone structures. They also started

Some contend that the Anthropocene started with the appearance of agriculture, in light of the fact that specific horticulture related activities, for example, rice paddy water system and deforestation may have prompted sharp ascents in convergences of CO2 and methane as ahead of schedule as 8,000 years prior. Many trust that it was not until the Industrial Revolution that our abuse of fossil fuels and monumental increases of energy utilize and populace began to push us sufficiently far to demonstrate a recognizable human impact.

Humans began in Africa,they started using stone tools and fire to cook their food. They were hunters and gatherers, they gathered berries and other plants and hunted deer and other animals for meat. Humans then migrated to Asia and Europe, they spread across the continent. “ Genetic evidence suggests that soon after leaving Africa, they interbred to some extent with the Neanderthals and a mysterious population in Asia called the

Humans are the most unique species on Earth. We have gained the ability to things never accomplished before on Earth. We can control our environment, domesticate other species, and more importantly, form complex connections and societies with one another. However, it is widely debated about how we evolved from simple ape-like foragers to the meat-eating, community-building species we are today. In this paper, we will be looking at three authors: Richard Wrangham, Pat Shipman, and Frans de Wall. Each of which approach this question from different directions.

During the Paleolithic period, humans grouped together in small societies such as tribes, and survived by gathering plants and hunting wild animals.The Paleolithic is characterized by the use of stone tools, although at the time humans also used wood and bone tools. Humankind gradually evolved from early members of humanity, who used simple stone tools. They transformed into fully behaviorally and religious modern humans or Homo sapiens during the Paleolithic era. During the end of the Paleolithic Revolution or the Upper Paleolithic, humans began to

Nearly everything that a human does is in response to the environment. Our lives are defined by what is around us and what we find in front of us, whether this means accepting, dealing with or changing it. This has been the pattern since primates first stood up and became Homo erectus, and has continued until we considered ourselves doubly wise. The shape of the land affected where humans moved. Weather was something with which to contend. Fire affected humans until they conquered it – and herein lies the core of the relationship. The earth affects humans, and humans affect it back, viewing characteristics and patterns as problems and challenges, and finding a solution.

I chose a news article about the human environmental impact on animals. We have made some changes by adding animals to the Red list,which has caused more exposure of the animals that are more at risk at extinction. Many reason for this decline in animals is because of human activity. The more people come together the more change they can do for the environment. While other differ in opinion, which disregard animal moral status.(Kantian Ethics)

According to Webster dictionary, the word environment can be defined as “a : the complex of physical, chemical, and biotic factors (such as climate, soil, and living things) that act upon an organism or an ecological community and ultimately determine its form and survival b : the aggregate of social and cultural conditions that influence the life of an individual or community” (Merriam-Webster). Environmental risks are actual and or potential threat of adverse effects on living organisms and environment by effluents, emissions, wastes, resource depletion, etc., arising out of an organization's activities.
