Presentation on Anthrosphere

1. Presentation on Anthrosphere www.assignmentpoint.com

2. Anthrosphere • Interactions of Homo sapiens with all aspects of the environment • We are going to look at each sphere, the interactions, and the solutions as well as the problems created by the human race. www.assignmentpoint.com

3. Anthrosphere • Man and his direct ancestors (hominids) have graced the planet for only about three million years. For almost all of this period the human population totaled less than 5 to 10 million individuals. Homo sapiens have increased their numbers exponentially from 1650 to present rising to the current population of 5.5 billion. If this growth continued unabated, the human population would reach 8 billion in the year 2000, 14 billion in the year 2010, 60 billion in the year 2020, and infinity by the year 2023. www.assignmentpoint.com

4. Of course, unlimited growth in an environment of finite resources is impossible because growth will eventually deplete the available resources and the population will collapse. Indeed one of the kindest things that the human species could do for planet Earth is to control the rate of growth of the anthrosphere. www.assignmentpoint.com

5. The anthroposphere (sometimes also referred as technosphere) is that part of the environment that is made or modified by humans for use in human activities and human habitats. It is one of the Earth's spheres. • As human technology becomes more evolved, such as the greater ability of technology to cause deforestation, the impact of human activities on the environment potentially increases. www.assignmentpoint.com

6. On the Earth, the anthrosphere mainly refers to our events over the past 10,000 years, because it is in that period of time that our activities have had an increasingly large impact on our environment (especially over the past 100 years). www.assignmentpoint.com
