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

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
