Mass extinctions

our future. But what impact did humans have thousands of years ago when they were first colonizing North America? The question of what caused the extinction of megafauna during the Late Pleistocene period is one that archaeologists have struggled to answer for decades, but why should it matter? Discovering with certainty the cause of megafaunal extinction would

Global Systems 1. List examples of human activities that are suggested to be key triggers for the sixth mass extinction. • Fossil fuels • Mass hunting • Deforestation • Mass fishing 2. Do you agree or disagree with this suggestion? Justify your response. I was think that is true because this is what happens when you think you have a lot of something and than its gone and than you have none of that stuff left and people don’t think about after they are always think about now and

“The Holocaust” was a mass extinction of several minority groups by the Nazi regime who believed they were the superior race (Introduction, n.d. par 1). The races and groups of people that were targeted during The Holocaust were Jewish people, Roma (gypsies), Polish people, Russian people, disabled people, homosexuals, and many other races and groups of people (Introduction, n.d. par 2). Over nine million people died during the Holocaust, causing it to be known as a mass extinction (Introduction, n.d

The mass extinction of the dinosaurs In the modern world Volcanos and Asteroids many seem completely different but they both happen to have similar effects. Around sixty-five million years ago a mass extinction occurred wiping out many animals, including all the dinosaurs. There are many theories towards this mass extinction but the two theories with the most scientific background knowledge is the asteroid theory and the volcanic theory (National Geographic, 2017). These two theories both could

events in climate changes are the mass extinctions that they associated with. Currently we are undergoing the sixth great mass extinction event in our planet's history. While several of these events were due to volcano activity or asteroid strikes, others were due a change in Earth's climate. It is estimated that the Earth is losing species to extinction at 1,000 to 10,000 times the natural rate (The Extinction Crisis, n.d). The primary driver for this extinction event are humans. Several factors

like what they might have looked like, what they ate, and where they lived but the biggest mystery that still has not been explained is, what exactly caused this mass extinction of dinosaurs to be wiped off the face of the earth?Dinosaurs lived for 165 millions years until 66 million years ago when they went extinct. In this mass extinction 70 percent of species including dinosaurs, plants, and ocean animals were hit the hardest and caused them to die. In the ocean organisms like foraminifera that

The Permian mass extinction occurred 251Ma and is recognised as having the largest volcanic eruption as one of the main antagonists to the event, it is also responsible for ~96% of all species to be wiped out. The main theories for the Permian event are the Siberian traps and the possibility of an impact event but the latter is widely disregarded. Global disasters tend to be an unfortunate coincidence of events. The combination of the background conditions in the late Permian of increasingly

known for the start of mankind and we’re still living in the period now! I predict that the Quaternary Period will end with a mass extinction of a dominate life form on Earth-maybe even the extinction of some humans! One reason a mass extinction can be plausible is because a lot of the previous periods have also been caused by mass extinctions. A lot of these extinctions were triggered by some change in the weather or atmosphere. Earth’s climate today, is becoming increasingly warmer and carbon

Earth’s Sixth Massive Extinction? After many scientific studies about a sixth mass extinction on Earth, people have begun to doubt about our existence on Earth after this immeasurable extinction. Things like the possible beginning of a new epoch called Anthropocene, the high amount of lost species due to extinctions, climate change, deforestation and contamination could be the main reasons of this gigantic event which could lead to our disappearance on Earth. Species are disappearing at a rate

The Earth, housing over 8.5 million species and currently the only proven body in the universe to hold a biosphere, maintaining its population through constant stability cycles. When an undefined region maintains constant weather patterns annually, this is called climate. When these patterns dramatically change and new annual patterns are established the climate changes. Electricity production, the source of most modern technologies is mainly produced by the burning of fossil fuels, such as coal
