Earth s Impact On Earth - 1201 Words

Humans have changed the face of Earth from the moment they first arrived. We humans who rule the earth and live in the earth have changed in many ways; ever since we came we have had growth in population, impact has been greater. We cut down forests, emitting pollutants, spilling oil, burying toxic waste, dumping garbage in oceans. We have affected this earth in a very positive and a negative way ever since we arrived on this planet called earth. Let me take you on a journey of how humans have transformed over time. Before humans arrived on earth was a molten rock which took hundreds of years to cool down and then it rained for years which formed oceans and finally life started to form on earth. Earth began 4.6 billion years ago from the same cloud of gas (mostly hydrogen and helium) and interstellar dust that formed our sun. First organisms around 3.6 billion years ago were simple cells oxygen producing bacteria. Also many things happened during geological process such as crystallizing of molten rock and wearing a way of landmasses. Humans started arriving later and everything started to change. Humans arrived on earth 200,000 thousand years ago, time of climate change, modern humans (Homo sapiens) evolved in Africa. Like early humans, modern humans gathered and hunted food. They developed behaviors that helped them react to the challenges of survival. Around 40,000 years ago Humans become more modernized and they start moving out of Africa and towards Europe and Hunt andShow MoreRelatedEarth s Impact On Earth1834 Words   |  8 Pages Earth History Paper Earth has been around for billions of years, about 4.543 billion years to be more exact. Through the years, it is safe to say that Earth has changed significantly. The planet Earth formed billions of years ago from next to nothing, the Earth’s plates have moved to change the surface appearance and structure, life on Earth has evolved drastically, and Earth developed an essential atmosphere as well as oceans. As the Earth continues to change, humans continue to learn more aboutRead MoreThe Earth s Oceans And Its Impact On Earth1269 Words   |  6 Pages1). 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 comp letely depleted. That is exactly what happened off the shores of NewfoundlandRead MoreThe And Their Impact On Earth s Climate1435 Words   |  6 PagesSunspots and Their Impact on Earth s Climate The sun is an incredibly dynamic ball of mass and energy at the center of our solar system. The source of the sun s energy is nuclear fusion; where mass is converted into energy when protons (positively charged hydrogen atoms) smash together at incredible speeds at the center of the sun to form helium. Nuclear forces aren t the only thing acting on the sun, electromagnetic forces also play a vital role in the sun s dynamic behavior. Due to the unimaginablyRead MoreThe Impact Of Volcanic Eruptions On The Earth s Climate System Essay1391 Words   |  6 PagesWhen examining the influence and impacts of volcanic eruptions upon the earth’s climate system we have to consider occurrences both in the present and in the past. It has been noted by McGuire et al. that â€Å"Volcanic activity and environmental change have been linked during recent times and in the geological record.† (2002:88) With thousands of volcanic events having transpired since the Archean, there is an abun dance of evidence to support the theory that volcanoes have impacted our climate for overRead MoreThe Impact Of Space Travel On Our Earth s Climate Essay1430 Words   |  6 Pagesthe entire population, and it makes so much more sense to stop screwing up the planet we’re already on instead of trying to find a new one. In the past 200 years we’ve made a greater impact on our earth’s climate than we have in the preceding 200,000 years of our existence1, and it definitely hasn’t been a positive impact. Our climate cycles on its own over long periods of time, but this latest cycle has changed at a much more significant rate than any of the previous theorized cycles. We’ve had technologicalRead MoreThe World s Terrifying Impact On Earth Justifies New Anthropocene Epoch1752 Words   |  8 Pagesâ€Å"Humanity’s terrifying impact on Earth justifies new Anthropocene epoch† is the title of an article published in the Guardian newspaper in October 2014, the purpose of this essay is to assess if this statement was and is true. The geologic timescale comprises of Eons, Eras, Periods, Epochs and Ages, all of which fit into each other with Eon being the largest. Key geological events in the life of the planet are used to mark the transition from one of these chapters to another.

II. Thesis: I wish to share this information with you all today because it is up to us to end offshore drilling. If we all became more knowledgeable on the ramifications of offshore drilling, we could better know how to avoid it. I firstly want to address the significant environmental impacts of drilling, second the alternative we can employ instead of drilling, and lastly howRead MoreHow Choices I Have Made That Impact The Earth s Water Cycle874 Words   |  4 PagesThe Water Cycle This essay examines choices I have made that impact the earth’s water cycle. I have focused primarily on water conservation and acknowledged my greenhouse gas contributions. I have a new appreciation for the hydrologic cycle. I had not previously thought about the world’s water supply in terms of 1.39B cubic kilometers or that only one percent of this is available as fresh water for humanity to work with (not accounting for the polar icecaps, glaciers or ocean desalination efforts)Read MoreThe Moon Is The Only Natural Satellite Of Earth1436 Words   |  6 Pagessatellite of Earth. Its orbit is 384,400 km from Earth, the diameter is 3476 km and the mass is 7.35e22 kg. The moon is also Called Luna by the Romans, Selene and Artemis by the Greeks, and many other names in other mythologies. The Moon, of course, has been known since prehistoric times. It is the second brightest object in the sky after the Sun. As the Moon orbits around the Earth once per month, the angle between the Earth, the Moon and the Sun changes; we see this as the cycle of the Moon s phasesRead MoreThe Effects Of Global Warming On The World1267 Words   |  6 Pagesthreatening issue that scientists and the government have been cognizant about. Global warming is the term used to describe a gradual increase in the average temperature of the Earth s atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. The earth periodically warms up and cools down. The Earth is currently going through a warming trend that coincides with the industrial revolution. This threat has cause several negative influx in our world. For instance, higher
