The Earth Has Vast Oceans

Planet Earth is the third planet from the Sun and the fifth largest of the planets of the Solar System. Earth’s surface is 71 percent water and is the only astronomical planet currently known where life exists. Earth is our home planet. Scientist and astronomers have studied our planet for Centuries and they have discovered much about our planet. Scientist have gained so much more knowledge of our Solar System in the last half-century after the NASA launched the first spacecraft and travel beyond Earth’s atmosphere has opened up to those who wish to explore. In the following paragraphs, we will discuss Earth and the

The history of life on earth goes back to millions of years. Many species and creatures evolved and changed through time, leading up to what we know today as, modern man. One of the creatures most similar to modern man is the Neanderthals; they are sometimes referred to as “early modern humans.”

The evolutionary of human living has taken place over millions of years of geological time. It has evolved millions of generations, and billions of individuals. The human evolution is not understandable completely yet. Evolutionary change within a population can take place at different time and different rates, which yield different consequences. This process still taking place in the natural selection and human evolution. One species may be merged to the new species or developed to the next stage of the same species. Homo Habilis, Homo Erectus, Homo Heidelbergensis, and Neanderthals were the close ancestors of modern human, which developed from Australopithecus afarensis.

The earth’s oceans are overfished. Nearly 80 percent of commercial fisheries are overexploited and some experts believe that global fisheries will completely collapse by 2048 (Barkin page 1). While these are just facts that tell the worst-case scenario, they should be alarms that spark change in the way we fish. This paper, however, will specifically target overfishing in the Grand Banks in Newfoundland, Canada, and analyze its impact on Earth, its Environment and Humanity. Over fishing is simply when fishermen catch more fish than are being reproduced. Eventually the stock of fish in the environment will be completely depleted. That is exactly what happened off the shores of Newfoundland in 1992. With Cod fishing at an all time high, the Canadian government discovered that the Cod population was almost exhausted. New technology and poor decision-making led to the complete destruction of the cod population in the Grand Banks and this is a mistake that we should never repeat.

The earliest stage of human evolution came to be found in Africa. Human history began about 7 million years ago and came from a descendant of the gorilla line. These early humans known as Homo erectus dispersed to different continents and started colonizations. Since every human being came from the same background it supports diamond’s theory that different human intellectuals wasn’t the cause of different advancements. As the inhabitants of Africa started to create new tools Europe and Asia began to follow this trend. As of some 400,000 years ago, Cro-Magnons in Europe developed modern skeletons, superior weapons, and other advanced cultural traits, a sign human evolution.

timeline of modern humans, Homo sapiens, and how long they have been in existence. According to mainstream science, popular belief holds that the history of our species is confirmed to be confined to the past 12,000 years. This figure is a culmination based on what we know about evolution and what we have been able to gather through fossil analyzation and dating of artifacts as well as human remains. Although the subject of human antiquity, also referred to as human origins, does not prompt a great deal of debate there may actually be the need for some. A reexamination of the notion that humans have only existed a mere 12,000 years should be considered as there may be evidence to support a much greater antiquity of modern human life. Alternative researchers have offered up evidence of “forbidden archeology” that contradicts the mainstream beliefs of human origins, however these discoveries seem to have been swept under the scientific rug.

Before the Neolithic Revolution, which began around 8000 B.C.E., the first human species, Homo sapiens, appeared in Africa 2.5 million years ago. As they evolved, the humans developed new uses of tools to equip themselves properly to hunt and gather, which more so began around 750,000 B.C.E. While hunting and gathering was a successful way to survive as a society, it was very dependent on their surrounding environment, causing the people to have to constantly migrate as the game population fluctuated. Through tens of thousands of years , the people spread widely across the globe stretching from Africa, Mesopotamia (now known as the Middle East), Asia, Eastern Europe, and parts of Latin America. The ending point of this time period began as

Earth as we all know it's Associate in Nursing improbably complicated and fragile network of interconnected systems that have developed slowly over the last four.5 billion years more or less. From the ashes of the massive Bang, this planet emerged as a mass of energy and components. From that new born mass of energy and components evolved structured, dynamic systems of solids, liquids, and gasses. The evolution of this planet continued to unfold over billions of years in such a novel method that eventually conditions arose with the flexibility to foster life.

According to physical evidence, and theories, scholars have concluded upon a whole hypothesis. Based on their knowledge and belief, modern humans diverged from Homo sapiens between 200,000 and 150,000 years ago specifically in Africa, that between 125,000 and 60,000 years ago members of Homo sapiens left Africa, and that these

Earth-sized planets are every common, and early data suggest that such planets are also common in habitable zones. It seems reasonable to suppose that a significant fraction of all stars have at least one habitable planet, which means there should be many billions of habitable planets in our galaxy. The flife presents more difficulty, because we do not yet have any reliable way to estimate the fraction of habitable planets on which life actually arose. However the rapid appearance of life on Earth and the fact that laboratory experiments suggest possible ways in which life could have arisen both make it seem that life should be likely on habitable worlds. in that case, we might expect most or all habitable planets to also have life, making the fraction of flife close to

According to Anthropologists, human species dates back at least 3 million years. We lived as hunters and gatherers for most of our history. Following this way of life kept their total numbers small, perhaps less than 10 million. Later communities evolved through the introduction of agriculture which could support more people.

The earth is so far the known planet to sustain life. Starting as small dense group, humans have populated the earth to where they the most populated species on earth. When humans first populated the earth, they did not live long lives. Disease, animals, and natural disasters made life on earth a nightmare. As humans

What is life? This is a difficult question to answer, largely because life itself is not a simple concept. About four thousand five hundred million years ago the Earth collided with a planetoid the size of Mars. At this time, fragments orbiting the Earth formed the

The ocean is one of Earth's most valuable natural resources. It provides food in the form of fish and shellfish—about 200 billion pounds are caught each year. It's used for transportation—both travel and shipping. It provides a treasured source of recreation for humans. It is mined for minerals (salt, sand, gravel, and some manganese, copper, nickel, iron, and cobalt can be found in the deep sea) and drilled for crude oil.

Humans have existed on Earth for approximately 3.4 million years. The oldest known human ancestor is "Lucy," an Australopithecus. Over this extensive period of time, humans have evolved significantly. Homo Sapiens have grown from 3 to almost 6 feet (average), lost most of the body hair, became leaner and adapted to walking. Humans have come a long way, from Australopithecus to Homo sapiens, from living in trees to living in cities. Slowly, through hundreds of thousands of years, we mutated over and over again, natural selection ensuring that no destructive mutations continue. From the slow evolution, four distinctive species emerged and died out, each giving way to its ' descendant: Homo Habilis, Homo Erectus, Homo Sapiens Neanderthalesis, and Homo sapiens Sapiens.
