Activity 2.3-Bioshpere and Interconnections


     The biosphere consists of all living layers which consumes Earth and make plant and animal life possible. In other words, the biosphere is the part of Earth where life exists. The biosphere contains biotic and abiotic components and there are interactions between living organisms and physical environmental. The biosphere provides all the necessary requirements for a living condition on Earth. Parts of the lithosphere, hydrosphere, and atmosphere make up the biosphere. The lithosphere is the outermost layer of the Earth's crust; essentially land is part of the lithosphere. The hydrosphere is composed of all the areas that contain water, which can be found on, under, and over the surface of Earth.  Living organisms are required to adapt to the environment of the biosphere. The biosphere is home to biodiversity within ecosystems while providing a reliable source of food on Earth. Abiotic components are considered the sub-systems of biosphere systems. Abiotic components are considered as land and soil where as biotic components consists of the plant system, animal system and micro-organisms. Plants are the most important component because plants produce organic matters which are used by themselves and by animals including micro-organisms either directly or indirectly.  The study of plant component include the consideration of classification of plants, plant kingdoms and plant systems. On a functional basis the biotic and organic components of biosphere ecosystem are divided into two broad divisions. The main functions of the animal components include to use organic matter, to rearrange the organic matter and to decompose organic elements. In conclusion the biosphere consists of three major types of habitats include the aquatic habitat, terrestrial habitat and aerial habitat.

 During the last decade within the twentieth century environmental growth was significantly high. Society was able to gain higher knowledge of the environmental challenges and issues the United States faced. The Brundtland report provided a explicit voice around these issues through analysis of human life based on social networks and ecological systems. Many environmental historians who have studied the U.S. policy facing these economic challenges came to conclusion that there were three main time periods which new concepts and ideas evolved. These three time periods were (1) the American conservation movement, (2) the rise of environmental risk management as a basis for policy and (3) the integration of social and economic factors to create the sustainability of paradigm. During The American Conservation Movement most early colonists who arrived to the states noticed that much of the land had very limited resources and there was minimal effort to treat and minimize wastage.
