Essay first draft
Evolving from ape-man society to the advanced civilization nowadays, people start to inhabit in artificial concrete jungle and live far away from the given natural environment. With social progression and economic benefits, peoples' crave for natural resources keeps escalating from time to time. People have a great tendency to consume resources yet ignore the long-term behavioral consequences that are destined to cycle back eventually. The significance of sustainability is mostly overlooked. The book 'Human Science and Human History 101' considers the planet and human as a whole system and tells the story in an informational scientific way. The book contains four main topics. Firstly introduce the formation history of the Earth and facts about different parts and components of the Earth to provide readers a solid concept and basis of the planet. Afterwards, it gradually explores the fact that human generation development and evolution are greatly determined by the changes on the Earth, for instance, the uncontrollable natural catastrophe-volcano eruption. Hence it evaluates the resulting impacts and relationships between human development and the Earth as a circulating ecosystem.
The first chapter starts with the exploration of the history and facts of atmosphere, oceans and rivers. An introduction of the atmosphere composition and certain scenarios of greenhouse effect and ozone depletion spark off the chapter. The sun gives life to the Earth. It provides a primary energy source to the Earth. Solar energy of the sun breeds and sustains the living things. Temperature on the Earth simply controls climates and determines changes on the living environment and consequently triggers alterations in human behaviors, which creates human history through centuries. This chapter specifically links the variation of solar radiation to the changes on surface of the Earth and history of mankind. The aforementioned changes in solar radiation are explained by long-term cycles. (Chapter 1, P.5) With obtaining the trapped gas of carbon dioxide in ice to determine the information about the changes in atmospheric temperature, in which a 100,000 years of slow cooling in glacial periods and 20,000 years of rapid warming in interglacial periods can be investigated. Climate changes create different periods and with the start and end of different periods generate distant consequences hence affect and shift living of human. From the long history of 1,5000 years ago, increasing temperature leaded to the melting of water and terminated the last Ice Age. With the end of last Ice Age, three main consequences - topographic effects of deglaciation, peopling effect of the Americas and the possibility of the occurrence of biblical flood in the Black Sea occur. (Chapter 1, P.15) These three effects further mold the surface of the Earth with the junctions of rivers, separation of the Earth continents and expansion of sea area. Firstly, 'topographic effects of deglaciation' discusses the physical evidence of glaciation on land and rapid sea level rise. The melting of ice uncovered the land and exposed much of the topography of North America and northern Europe. Secondly, 'peopling of the Americas' confers the idea of very different evolution patterns between South and North Americas using examples of primates, hominins and Homo sapiens. The circumstance was leaded by the isolation of North America by the opening of the Atlantic and Arctic Oceans. Thirdly, 'Flooding of the Black Sea' tells that the Black sea was once isolated, and by connecting the Black Sea with other world's ocean by melting ice, the...
