priests also promoted clashes with the mountain and desert folk. On the other hand‚ deforestation due to overgrazing and ploughing of fields caused the frequent floods in Mesopotamia to have a larger than normal effect. Woodlands at first used to absorb most of the rain water but due to deforestation‚ the soaking up of the water did not work (Wright‚ p 74). The Sumerians destroyed their own civilization due to deforestation which caused disastrous floods‚ too much faith in the priests and clashes with

Chapter 11 : Soil: The Foundation for Land Ecosystem Chapter 11 Brooke Settles Chapter 11 discusses three major practices that expose soil erosion and how they can be corrected . The three are Over- cultivation‚ Overgrazing and Deforestation. These are each all major problems in creating an unsustainable society. The good thing is that each of these causes of erosion can be corrected to create a more sustainable society. First there is Overcultivation which is the practice of repeatedly

Some theories even go to the extent to postulate a lack of affirmative action by Mayan kings which could have saved the civilization. Archaeologists have made several attempts to come

Pollution Human beings have always caused some environmental pollution. Since prehistoric times‚ people have created waste. Like garbage today‚ this waste was either burned‚ tossed into waterways‚ buried‚ or dumped aboveground. However‚ the waste of early peoples was mostly food scraps and other substances that broke down easily by natural decay processes. Prehistoric populations were also much smaller and were spread out over large areas. As a result‚ pollution was less concentrated and caused

CLIMATE CHANGE: HOW THE HOMO SAPIENS HAVE CONTRIBUTED By Ernest Ebo Jackson TERM PAPER Climate change refers to change in average weather patterns and can be caused by both natural processes and human activities. In the past‚ the earth’s climate has been affected by natural factors such as changes in solar output and the discharge of volcanic ash. In fact‚ the planet has been through many periods of cooling and warming. The last period of major cooling ended about 10‚000 years ago.
