The Great Dying: The Cause Of Death

Superior Essays
Five times in the history of Earth, mass extinctions of unimaginable death scale almost wiped out most of the life on the planet. The last event occurred 65 million years ago when Earth was impacted by an asteroid killing the dinosaurs and other organisms (70 per cent of the species). The deadliest of these extinction events happened more than 252 million years ago. The event is known as the Permian-Triassic Extinction Event or the “Great Dying” that killed around 90 per cent of all species on Earth. This event was caused by a series of volcanic eruptions that released great amounts of Carbon Dioxide (CO2) and other greenhouse into the atmosphere triggering a rapid global warming and climate change. Nowadays, scientists predict that we are …show more content…
Species that lived on the planet during the Permian period were unable to generate CO2 to levels of mass extinction. The main suspects are located in the East Siberia basins in Russia, where series of massive volcano eruptions ravished more than 1 million square miles of land pouring huge amounts of CO2 and other greenhouse gases into the atmosphere. As temperatures increased during this event, the currents of the oceans decreased diminishing the flow of oxygen creating death zones. Changes happened so fast that most creatures could not adapt. How can we compare this event to our world …show more content…
Current advances in material technology, building design and renewable technology offer the promise of zero emission cities in the near future. By using new high technological materials and urban planning, humans can build clean, green and self-sustainable cities. Currently, there are several examples in Europe, Asia, the Middle East and America.
In the United Arab Emirates for example; a country connect with the production of fossil fuels, is using its wealth to build Masdar City, an extraordinary project that will run only with renewable energy. More than 95% of the materials use to build this city is recyclable. The city targets are to be the first one with zero carbon, zero waste and fossil fuels free. The ultimate goal of its design is to have the highest quality of life with the lowest environmental impact. Masdar is a City that shows what can be done and set an example for other

    Meghan Lewis Dinosaur Case Study September 25, 2017 Introduction Imagine if after 6 million years of existing on earth, the entire human race died out by the year 3320. Within a mere 1000 years’ all of humanity would be wiped from existence. This was the case with the dinosaurs and many other species living in the Mesozoic-Cenozoic period. 65 million years ago a meteorite roughly 10 km across hit the earth’s surface, and the impact would be a catalyst to the extinction of 75% of the species living on earth at the time, including the dinosaurs. The impact of the meteorite would have instantly killed any organisms within proximity.…

    The energy source we need to advance in, is clean energy. As Siena Kaplan, Brad Heavner, and Rob Sargent, state: “If we clean up the electric grid by reducing our use of polluting energy sources and increasing our use of clean energy sources such as wind and solar power, we can maximize the environmental benefits of plug-in vehicles” (The Advantages of Plug-in Cars). This would help slow the progress of global warming significantly. Pure electric cars are just as beneficial. The only problem with pure electric cars, is most people need a vehicle they can use without the anxiety of being restricted by range.…

    The extinction of dinosaurs is commonly attributed to a large bolide impacting the Earth and a massive series of volcanic eruptions at the end of the Cretaceous period (Brisman et al. 2001). Either of these proposed hypotheses could account for the short-term (rapid) cooling, cessation of photosynthesis, acid rain and extensive wildfires that ultimately led…

    It is the only active volcano in Europe’s mainland. The volcano is very dangerous because of the large population of people in the city below it. It is classified as a complex stratovolcano because it explodes and had pyroclastic flows, which means it consists of rock pieces. It had some major eruptions for example: the “Avellino eruption” that occurred in about 1780 B.C.. Lava, ash, and rocks plummeted 22 miles into the sky. The prehistoric catastrophe completely destroyed everything.…

    These fumes affected the surrounding areas greatly and even reached around the globe, causing acid rain. As a result of this radioactive pollution, three hundred and thirty six thousand people had to be relocated to a safer area (Top 10 Worst Engineering Disasters). A worker died from the explosion, and another worker died shortly after in the hospital. Within three months of the explosion, thirty operators and firemen that were working on the plant were also killed (Chernobyl Accident 1986). After those three months, many more people died because of radiation poisoning and cancers that were developed.…
