Leipzig vs Earth

Informations

Leipzig (, also , , German: [ˈlaɪptsɪç] (listen); Upper Saxon: Leibz'sch) is the most populous city in the German state of Saxony. With a population of 600,000 inhabitants as of 2019 (1.1 million residents in the larger urban zone), it is Germany's eighth most populous city as well as the second most populous city in the area of former East Germany after (East) Berlin. Together with Halle (Saale), the largest city of the neighbouring state of Saxony-Anhalt, the city forms the polycentric conurbation of Leipzig-Halle. Between the two cities (in Schkeuditz) lies Leipzig/Halle Airport. Leipzig is located about 160 kilometres (99 mi) southwest of Berlin in the Leipzig Bay, which constitutes the southernmost part of the North German Plain, at the confluence of the White Elster River (progression: Saale→ Elbe→ North Sea) and two of its tributaries: the Pleiße and the Parthe. The name of the city as well as the names of many of its boroughs are of Slavic origin. Leipzig has been a trade city since at least the time of the Holy Roman Empire. The city sits at the intersection of the Via Regia and the Via Imperii, two important medieval trade routes. Leipzig was once one of the major European centres of learning and culture in fields such as music and publishing. After the Second World War and during the period of the German Democratic Republic (East Germany) Leipzig remained a major urban centre in East Germany, but its cultural and economic importance declined. Events in Leipzig in 1989 played a significant role in precipitating the fall of communism in Central and Eastern Europe, mainly through demonstrations starting from St. Nicholas Church. The immediate effects of the reunification of Germany included the collapse of the local economy, which had come to depend on highly polluting heavy industry, severe unemployment, and urban blight.

Starting around 2000, however, the decline was first arrested and then reversed and, since then, Leipzig has seen significant changes with the restoration of major historical buildings, the demolition of derelict properties of little historical value, and the development of new industries and a modern transport infrastructure.Leipzig today is an economic centre, is rated as the most livable city in Germany by the GfK marketing research institution, and has the second-best future prospects of all cities in Germany according to HWWI and Berenberg Bank. The city is one of two seats of the German National Library, as well as the seat of the German Federal Administrative Court. Leipzig Zoo is one of the most modern zoos in Europe and ranks first in Germany and second in Europe. Since the opening of the Leipzig City Tunnel in 2013, Leipzig forms the centrepiece of the S-Bahn Mitteldeutschland public transit system. Leipzig is currently listed as a "Sufficiency" level global city by the Globalization and World Cities Research Network, Germany's "Boomtown" and was the 2019 European City of the Year.Leipzig has long been a major centre for music, both classical as well as modern "dark alternative music" or darkwave genres. The Oper Leipzig is one of the most prominent opera houses in Germany. Leipzig is also home to the University of Music and Theatre "Felix Mendelssohn Bartholdy". The Leipzig Gewandhaus Orchestra, established in 1743, is one of the oldest symphony orchestras in the world. Johann Sebastian Bach is one among many major composers who lived and worked in Leipzig and, during a stay in the city, Friedrich Schiller wrote his poem "Ode to Joy".

Earth is the third planet from the Sun and the only astronomical object known to harbor life. About 29% of Earth's surface is land consisting of continents and islands. The remaining 71% is covered with water, mostly by oceans but also lakes, rivers and other fresh water, which together constitute the hydrosphere. Much of Earth's polar regions are covered in ice. Earth's outer layer is divided into several rigid tectonic plates that migrate across the surface over many millions of years. Earth's interior remains active with a solid iron inner core, a liquid outer core that generates Earth's magnetic field, and a convecting mantle that drives plate tectonics. According to radiometric dating estimation and other evidence, Earth formed over 4.5 billion years ago. Within the first billion years of Earth's history, life appeared in the oceans and began to affect Earth's atmosphere and surface, leading to the proliferation of anaerobic and, later, aerobic organisms. Some geological evidence indicates that life may have arisen as early as 4.1 billion years ago. Since then, the combination of Earth's distance from the Sun, physical properties and geological history have allowed life to evolve and thrive. In the history of life on Earth, biodiversity has gone through long periods of expansion, occasionally punctuated by mass extinctions.

Over 99% of all species that ever lived on Earth are extinct. Almost 8 billion humans live on Earth and depend on its biosphere and natural resources for their survival. Humans increasingly impact Earth's hydrology, atmospheric processes and other life. Earth's atmosphere consists mostly of nitrogen and oxygen. Tropical regions receive more energy from the Sun than polar regions, which is redistributed by atmospheric and ocean circulation. Greenhouse gases also play an important role in regulating the surface temperature. A region's climate is not only determined by latitude, but also by its proximity to moderating oceans and height among other factors. Extreme weather, such as tropical cyclones and heat waves, occurs in most areas and has a large impact on life. Earth's gravity interacts with other objects in space, especially the Sun and the Moon, which is Earth's only natural satellite. Earth orbits around the Sun in about 365.25 days. Earth's axis of rotation is tilted with respect to its orbital plane, producing seasons on Earth. The gravitational interaction between Earth and the Moon causes tides, stabilizes Earth's orientation on its axis, and gradually slows its rotation. Earth is the densest planet in the Solar System and the largest and most massive of the four rocky planets.
